摘要：

The aim of this work was to design solar cells with dual junction amorphous silicon/amorphous silicon germanium (a-Si:H/a-Si1-xGex:H) absorber structure. However, thin film solar cells still suffer lower conversion efficiency and need to be improved using innovative technologies. In the present work, p-a-Si:H, i-a-Si:H, i-a-Si(1-x)Gex:H and n-a-Si:H layer with the same band gaps of 1.8 eV, the thickness equal to 5 nm, 340 nm, 5 nm and 5 nm respectively, and acceptor and donor concentrations are constant and equal to 3x10(19) cm(-3) and 1x10(19) cm(-3), respectively, are optimized for obtaining efficient a-Si:H p-i-i-n solar cell by computer aided one-dimensional Analysis of Microelectronic and Photonic Structures (AMPS-1D) simulation program. To improve the performance of a-Si(1-x)Gex:H we investigate: i) the band gap effect of a-Si(1-x)Gex:H, ii) the thickness effect of a-Si(1-x)Gex:H on the conversion efficiency of solar cell. Simulation results show that considerable efficiency enhancement can be obtained.
