Abstract
The ZnS/CuInGaSe 2 heterojunction solar cell fabricated on Mo coated glass is studied. The crystallinity of the CIGS absorber layer is prepared by coevaporated method and the ZnS buffer layer with a band gap of 3.21 eV. The MoS 2 phase was also found in the CuInGaSe 2 /Mo system form HRTEM. The light soaking effect of photoactive film for 10 min results in an increase in F.F. from 55.8 to 64%, but series resistivity from 7.4 to 3.8 £[. The efficiency of the devices improved from 8.12 to 9.50%. ? 2013 Yu-Jen Hsiao et al.
