Abstract: In order to increase Voc and improve the spectral response of CdS/CdTe solar cells,thus increasing their efficiency,we bring forward a new tandem structure.The top cell consists of thinner CdS/CdTe layers,and the bottom cell structure of thicker CdS/CdTe layers.The total structure is Glass/SnO2/CdS/CdTe/CdS/CdTe/ZnTe:Cu/Ni.The structural properties of the tandem solar cells have been investigated,revealing its different layers and showing that it has Voc of 852mV,Jsc of 13mA/cm2,and FF of 55.2%.The spectral response of the cell is improved,and it is demonstrated to have an efficiency of 8.16% for 0.071cm2 cells.Compared to the ordinary monolayer CdS/CdTe solar cells,the CdS/CdTe tandem solar cells have important value for investigating how to improve CdS/CdTe solar cells’ photovoltaic performance.
Key words: top cell, bottom cell, CdS/CdTe tandem solar cell
