Insulation and diffusion barrier characteristics of spin-on-glass layer on a stainless steel substrate

Ming-Jer Jeng, Wei-Jer Lai, Bai-Zong Chang, and Sung-Cheng Hu The efficiency of CIGS (Copper Indium Gallium diSelenide) solar cells fabricated on stainless steel foil is lower than that on soda-lime glass substrates due to the lack of sodium incorporation and metal impurity diffusion. A dielectric barrier is necessary to prevent metal impurity diffusion for st ... [J. Renewable Sustainable Energy 4, 011603 (2012)] published Wed Feb 8, 2012.
