### Abstract

Polycrystalline cadmium telluride (CdTe) is the leading material for realization of low cost and high efficiency solar cell for terrestrial use. In this work, the CdTe conventional structure [1] was investigated and achieved the maximum conversion efficiency of 13.2% with CdTe baseline structure of SnO _{2}/CdS/CdTe. To explore the possibility of ultra thin and high efficiency CdS/CdTe solar cell, the CdTe absorber layer and CdS window layer were decreased and found that 1 μm thin CdTe layer showed reasonable range of efficiency. Moreover, it was found that there were scopes to increase cell efficiency by reducing the cadmium sulfide (CdS) window layer thickness. The CdS window layer was reduced to 60 nm with insertion of zinc oxide (ZnO) or zinc stannate (Zn_{2}SnO_{4}) as a buffer layer to prevent forward leakage current. All the simulation have been done using Analysis of Microelectronic and Photonic Structures (AMPS 1D) simulator. The maximum conversion efficiency of 18.3% (Voc = 1.00 V, Jsc = 26.15 mA/cm^{2}, FF = 0.769) was achieved with 1 μm-CdTe absorber layer, 60 nm-CdS window layer and 100 nm of ZnO or Zn_{2}SnO_{4} buffer layer. Moreover, it was found that the cell normalized efficiency linearly decreased with the increasing operating temperature at the gradient of -0.4%/° C, which indicated better stability of the CdS/CdTe solar cells.
