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 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 ：
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 ：
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 ：
The operating temperature influences both the electrical efficiency and thermal efficiency of a photovoltaic thermal (PVT) module. In this paper, a simplified thermal transfer model is used to search for the optimal structure of a high efficiency PVT module. For an aluminum collector with a given thickness, the optimal ratio between size and spacing and cross sectional geometry of the flow channels has been found with numerical simulations using computational fluid dynamics (CFD). The temperature distribution of the PVT module constructed with an aluminum collector is found to be more uniform than the conventional sheet-tube PVT module, due to using an improved thermal transfer mode based on the surface contact. To evaluate the impact of cross sectional geometry, the operating temperatures, electrical and thermal efficiencies of two PVT modules designed with rectangle and arch geometries are examined under outdoor conditions. Measured experimental intercept values of instantaneous thermal efficiencies are close to simulation results, demonstrating the utility of the approach as a reference for a new generation of PVT modules in future.

摘要 ：
The quasi one-dimensional layered KP15 shows in-plane anisotropic electrical/optical properties and high carrier mobility. In this work, for the first time, its electrical/optical properties are studied by fabricating phototransistors based on mechanical exfoliated KP15 nanowires. The device shows high specific detectivity (>10(10) Jones throughout the visible band with peak value > 10(12) Jones) and fast response time (similar to 10 ms, shorter than most photodetectors based on 2D Mo or W sulfides). The excellent device performance suggests KP15 as a new candidate material for photonic and optoelectronic devices. (C) 2020 Elsevier B.V. All rights reserved.

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 ：
Crystalline silicon heterojunction with intrinsic thin-layer photovoltaic (HIT-PV) module produces more output power, compared with the c-Si photovoltaic module. However, it presents a risk of overheating in hot weather. In this paper, we used a new cooling design of the heterojunction with intrinsic thin-layer photovoltaic thermal (HIT-PVT) module to lower the temperature using laminated encapsulation of an aluminum collector in outdoor climates. The measured electrical, thermal and total efficiencies of a HIT-PVT system can catch up to 17.47%, 34.71% and 52.18%, respectively. Moreover, comparing with HIT-PV module, the output power of the HIT-PVT module was enhanced by 5.58% with coolant circulation, and the converted electrical energy can be increased by 9.81% with the designed HIT-PVT module. In addition, the primary energy savings of the new HIT-PVT and HIT-PV systems were 79.77% and 43.71%, respectively.
