Efficiency enhancement of CIGS compound solar cell fabricated using homomorphic thin Cr2O3 diffusion barrier formed on stainless steel substrate
Autor: Haeng-Keun Ahn, Cheul-Ro Lee, Jin Soo Kim, Kwang-Un Jeong, Seung-Kyu Lee, Jae-Kwan Sim
Publikováno v: Applied Surface Science. 389:645-650
It is known that the efficiency of flexible Cu(In,Ga)Se2 (CIGS) solar cells fabricated on stainless-steel (STS) substrates deteriorates due to iron (Fe) and Cr impurities diffusing into the CIGS absorber layer. To overcome this problem, a nanoscale h
