Abstract
The present invention relates to a laminate including an alkali metal-doped layer. The laminate is processable at high temperatures of at least 550° C. and has excellent durability and barrier properties. Due to these advantages, the laminate can be used to fabricate a thin film solar cell with high flexibility and improved energy conversion efficiency. The present invention also relates to a thin film solar cell including the laminate.
