Polycrystalline Thin-Film Technologies: Status and Prospects

    Research output: Contribution to journalArticle


    The recent progress towards high-efficiency thin-film polycrystalline solar cells is examined in this paper together with a brief history of their development. We focus on the three materials of contemporary interest for such devices: polycrystalline Si, CuInSe2 and its alloys, and CdTe. Although there has often been an implicit assumption that thin-film devices required a compromise of lowerefficiency than their single, or bulk polycrystalline competitors, we now see for the first time that polycrystalline thin-film solar cells can rival these devices. In dispelling this myth, we examine the elements that have contributed to the progress in each area.
