Polycrystalline thin film solar cells

Abstract

Present status, manufacturing perspectives, and critical issues of polycrystalline thin film solar cells are reviewed. The paper is focused on CdTe and CuInSe2 based heterostructure solar cells for which significant progress has been achieved in recent years. Material aspects and basic film characteristics that are important for good cell performance are discussed. Preparation methods of CdTe and CuInSe2 films are presented.
