In　this　work,　we　describe　some　aspects　of　the　Hanergy　silicon　heterojunction　(SHJ)　solar　cell　design　and　its　manufacturing-friendly　process.　Experimental　results　are　reported　mainly　with　regard　to　texturing,　silicon-based　thin　film　deposition,　and　transparent　conductive　oxide　(TCO)　coating　optimization.　A　conversion　efficiency　of　22.83%　with　V-OC　=　737.6　mV,　J(SC)　=　37.97　mA/cm(2)　and　FF　=　80.94%　on　a　full-size　M2　wafer　has　been　certified　by　Fraunhofer　ISE　CalLab.　Also　demonstrated　is　a　mean　efficiency　of　22.15%　during　a　45-day　pseudo-pilot　run.　Two　PV　stations　built　with　our　bifacial　60-cell　standard　SHJ　modules　harvested　12.1　and　18.3%　more　solar　energy　in　Chengdu　than　a　single-sided　n-type　monocrystalline　silicon　reference　PV　station,　mainly　owing　to　improvements　of　the　rear　side.　(C)　2018　The　Japan　Society　of　Applied　Physics
