摘要 ：
Due to the rapid development of the solar thermal utilization industry, the research on the factors affecting the life of components is not thorough, especially because of the need of market development. The non-standard parts provided by the supplier are not clear in the quality measurement index of the whole machine product life cycle, the fine management of the supplier, the continuous improvement of the product quality and other parts of the evaluation index are refined, and the cost, quality and service are established. The balanced scorecard dynamic management system based on process control for industrial suppliers of solar thermal utilization is of great theoretical value and practical significance. © 2021, Solar Energy Periodical Office Co., Ltd.

摘要 ：
The effect of plasma excitation frequency on the performance of intrinsic hydrogenated amorphous silicon (a-Si:H) films and heterojunction solar cells by radio-frequency (RF, 13.56 MHZ) and very-high-frequency (VHF, 40 MHZ) plasma-enhanced chemical vapor deposition (PECVD) have been investigated. The thickness and microstructure of intrinsic a-Si:H films were measured by spectroscopic ellipsometry and Fourier transform infrared spectroscopy (FTIR). The a-Si:H/c-Si interface passivation quality were determined by minority carrier lifetime and transmission electron microscopy (TEM). The current-voltage (I-V) performance of the HJT solar cells were also evaluated. The results reveal that a-Si:H films developed by RF-PECVD with a large area of parallel-plate reactors (> 1 m(2)) exhibit better thickness uniformity, lower microstructure factor, and higher minority carrier lifetimes. Hence HJT solar cells have achieved efficiency of 24.9%, compared with cell efficiency of 24.6% with intrinsic a-Si:H films developed by VHF-PECVD.

摘要 ：
The difficultness of Ga inclusion in conventional CuInGa plating can be solved by metal-oxide/hydroxide deposition. However, the selenization process with the oxide precursor is very difficult, because of the strong electronegativity of oxygen. In this work, we proposed a strategy of Cu(InGa)Se-2 thin films manufacture with selenization employing mixed precursor. The precursor consists of CuIn alloy and CuGa oxide/hydroxide, and deposited by electrodeposition as the sources of Cu, In and Ga. Then, the selenization process is performed in the mixed atmosphere of selenium vapor, hydrogen and argon. Meanwhile, we investigated the structural, optical and electrical properties of the prepared Cu(InGa)Se-2 thin films, and it implied both the deposition potential and the subsequent selenization time impact the structure and morphology of the thin films. The co-deposition of CuGa oxide/hydroxide improved the Ga deposition ratio, and it exhibited dendrite growth with large deposition potential. The subsequent selenization results in the transformation from the precursor to CuInSe2 and Cu(InGa)Se-2, as well as, the long selenization time lead to the oxygen concentration decreasing and high Ga concentration in CuInSe2 films. In the end, with a potential of -0.5 V versus Ag/AgCl electrode, the film had a photo-generated current density of 0.05 mA/cm(2), and the CIGS solar cell achieved a conversion efficiency of 1.85%.

摘要 ：
Due to the small work function and large resistance of intrinsic graphene, graphene-silicon Schottky junction solar cells have low VOC and JSC. For those problems, AFORS-HET is used to simulate the graphene-silicon Schottky junction solar cells. The simulation results show that the VOC can be improved with the increase of the band gap, acceptor concentration and work function of graphene. With the increase of the donor concentration of crystal silicon, the VOC is reduced from 494.1 mV to 386.6 mV. Finally, optimum efficiency of 11.92% has been achieved after simulating the thickness of crystal silicon and graphene layer, which is the maximum value of this kind of structure reported at present. © 2020, Solar Energy Periodical Office Co., Ltd.

摘要 ：
Environmental conditions and mass flow rates both influence the performance of hybrid photovoltaic thermal modules. In this work, the performance of a photovoltaic thermal module was investigated under two controlled laboratory environmental conditions: closed and ventilated air circulation. Comparing two different environmental conditions, we have examined the effect on operating temperature by the mass flow rate of coolant, varied over the range 0.05 kg/s to 0.10 kg/s. Experimental results, under indoor laboratory conditions, indicate there is a measurable effect from mass flow rate on the overall electrical efficiency in comparison to output at ambient temperature. Interestingly, the output power and electrical energy of the photovoltaic thermal module were observed to increase by 6.06% and 3.67%, respectively, under the conditions of ventilated air circulation. In addition, the maximum electrical and thermal efficiencies of the photovoltaic thermal module were estimated as 13.67% and 53.08%, respectively. Results obtained in this study provide a useful reference for applications of PVT modules requiring combined heat and power, such as commercial buildings and building integrated design.

摘要 ：
Copper indium gallium selenium (CIGS) based solar cells were thin film solar cells with high conversion efficiency. The conversion efficiency of CIGS solar cells prepared in the laboratory reached 22.9%, which was close to the highest conversion efficiency of crystal silicon solar cells. At the same time, CIGS cells also had the advantages of high absorption coefficient, low manufacturing cost, and wide application. However, in large-scale commercial production, CIGS solar cells were still far from silicon-based solar cells in terms of efficiency and stability. Further improving the efficiency of CIGS solar cells, expanding the scale of cells industrialization and optimizing their performance were the only way for the future development of CIGS solar cells. The main achievements of the current development of CIGS solar cells were mainly due to people's understanding of CIGS materials and device principles. In this paper, the potential and advantages of CIGS solar cells as a hot spot and recent research progresses on CIGS solar cells were reviewed, including the improvement of buffer layer, absorption layer and window layer, as well as the treatment methods between the layers. The development of these technologies improved the conversion efficiency of CIGS solar cells and promoted its industrialization. At the same time, the related problems in the future development of cells and the solutions were discussed. © Editorial Office of Chinese Journal of Rare Metals. All right reserved.

摘要 ：
The solar selective absorber coating (SSAC) are at the core of the efficient solar-thermal system. In this paper, for the first time, the Chromium-iron oxidation mixture cermet was successfully prepared on the surface of ultra-pure ferritic stainless steel by chemical coloring as SSAC. The coating surface has an optical trap structure, and the chromium-iron oxidation mixture cermet is used as an absorption layer to realize solar-thermal conversion. The solar absorptance (AM1.5) of the coating reached 93.66, and the thermal emittance was less than 13. After thermal shock tests at 25/300 degrees C done 32 times (accumulated 812.8 h), the Performance Criterion (PC) of the coating was 0.01375 < 0.05, showing outstanding thermal stability.

摘要 ：
High hydrogen content (C-H) intrinsic amorphous silicon (a-Si:H) buffer layers were deposited on both sides of crystalline silicon wafers using plasma-enhanced chemical vapor deposition technique, which significantly improved surface passivation as well as conversion efficiency of the silicon heterojunction solar cells. Properties of the buffer layer and impact on the device performance were investigated. High resolution transmission electron microscope characterization shows that no obvious epitaxial growth occurred at the interface as long as a-Si:H buffer layer was introduced between c-Si and bulk intrinsic layer. Further study indicates that minority carrier lifetime of the device is related to hydrogen content of the buffer layer, reaching highest value up to 2050 ms at C-H of 33%. These findings evidently confirmed that suppression of epitaxial growth and thus improved passivation were realized by using high-hydrogen-content a-Si:H buffer layer, based on which a high efficiency solar cell was prepared with large area.

摘要 ：
It is well known the efficiency of photovoltaic (PV) modules decreases with an increase in operating temperature. In this paper, we have investigated this phenomenon through classification of the flat plate photovoltaic/thermal (PV/T) collector into four configurations (air-type, water-type, nanofuid-type and bi-fluid-type), according to the media used for operation. Benefits of using the different operation media were assessed and an optimum for high overall efficiency of the PV/T collector was achieved. Considering different variation trends in electrical and thermal efficiency of the PV/T collector, the effects of operation media, structural designs and climatic conditions on performances of flat plate PV/T collectors were discussed in consideration of relevant literature reports. Results demonstrated that the overall efficiency of a water-type PV/T collector was greater than an air-type PV/T collector, benefitting from the higher specific heat capacity of water yet with a complex structure. The nanofluid-type PV/T collector presented a higher overall efficiency than the others, due to the high thermal conductivity of dispersing nanoparticles in a base fluid and the colloidal stability of the nanofluid. Furthermore, the glass cover (with or without), absorber structure and relative location between the absorber and the fluid influenced the overall performance of the PV/T collector. In addition, the primary climatic conditions to influence performance were solar radiation and environmental temperature, with a dependence on the geographical installation region. Future studies were considered through progression of advanced PV/T technologies, when the PV/T collector could be integrated with residential and public buildings.

摘要 ：
In this study, we investigate the effect of residual H2O pressure (P-H2O) on the structural, electrical, and optical properties of indium tin oxide (ITO) film and the current-voltage (I-V) performance of silicon heterojunction (SHJ) solar cells. The ITO films and SHJ solar cell were prepared under different P-H2O (3.75 x 10(-7) Pa, 6 x 10(-7) Pa, 10.25 x 10(-7) Pa) by varying the pumping time before starting the fabrication process. The experimental results revealed the crystallinity of ITO films was suppressed with the increase in P-H2O. Further, the sheet resistance of ITO films was reduced from 103 O/sq to 60 O/sq due to the enhanced carrier mobility, and the transmittance in near-infrared (NIR) region exhibited a slight increase, but the conversion efficiency of SHJ solar cells dropped dramatically from 23.3% to 22.79% due to the degradation of fill factor (FF). The analysis on n-a-Si:H/ITO and ITO/Ag contact properties indicated that such FF degradation could be attributed to the increased specific contact resistance for the two contacts, when P-H2O was high. Finally, SHJ solar cell with conversion efficiency of 23.53% was achieved by restraining the residual H2O vapor during ITO deposition along with the optimization of transmittance in NIR region by adjusting the amount of O-2 flow.
