Non-Vacuum Processing of CIGSe Solar Cells on Flexible Substrates Improved by Controllable Selenization on Ohmic-Contact Effect by JJ Ho* in Crimson Publishers: Peer Reviewed Material Science Journals
The blade coating and chemical bath deposition (CBD) techniques are employed as the non-vacuum process to form thin-film Cu (In, Ga) Se2 (CIGSe) on flexible (stainless-steel) substrates for the low-cost solar-cell industry. The best efficiency of 10.33% is obtained with the developed sample A2 after the selenization with optimisation of ohmic contact on CIGSe/Mo interface, which yields a gain of 26.75% absolute compared with that of a reference cell. In addition, the developed CIGSe thin-film with non-vacuum process are fast with simplicity and reliability and could be effectively applied to mass production in commercial applications.
