Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from the elements (rain, hail, etc.).
Solar cells are also usually connected in series in modules, creating an additive voltage.
CSG produced both Mono and Multi photovoltaic solar cell. We make 125mm Mono, 156mm Mono and 156mm Multi solar cell. Our 125mm Mono and 156mm Multi had TUV IEC 21615 and IEC 21730 certification, and we are in the process of applying TUV IEC certificate for 156mm Mono solar cell.
Our R&D team, continue striving to improve the efficiency of the solar cell. Our solar cell production of 125mm Mono has shown a mean efficiency of 17%. And we managed to produce as high as 17.8% efficiency. As for 156mm Multi has a mean efficiency of 15.8% and has peaked 16.5%.
