"Thin Film Solar Cell world's highest power conversion efficiency 12.6%... absorber layer produced coating copper, zinc, and tin in random order... reacting... sulfur and selenium at high temperatures... large pores were not formed when zinc was coated first. This is a source technology that can suppress pore formation and is expected to further increase the power generation efficiency... induced change microstructure... by changing deposition order... metal thin film... suppress pore formation"
