摘要：
A multijunction solar cell with the structure ZnSe/ZnTe/CdTe has been fabricated on tin oxide coated glass substrate by vacuum evaporation method. The multijunction ZnSe/ZnTe/CdTe solar cell showed remarkably higher conversion efficiency over the single layer ZnSe/CdTe solar cell. The conversion efficiency of the multijunction ZnSe/ZnTe/CdTe solar cell was found to depend on the thickness of the CdTe layer. Optical band gaps of each of the layers in the multijunction solar cell were calculated from the UV-Vis absorption spectra. The photovoltaic parameters of the cells were measured and the cell showed its best performance with the following set of photovoltaic parameters: I(sc) = 1.52 mA, V(oc) = 765 mV, conversion efficiency approximate to 10% and fill factor = 65.05%.
