Challenges in the industrial production of CZTS monograin solar cells

摘要

(CZTS) is non-toxic and comprises of abundant elements, which makes it to be very interesting for the application in solar cells. Recent progress on the understanding of the materials and devices resulted in increasing efficiencies and it is expected that these will increase further. For a commercial success of CZTS solar cells an industrial low-cost production is required. The CZTS monograin solar cell technology allows developing a solar cell production process independently from material and device research. Challenges and latest results on the roll-to-roll production of monograin CZTS solar cells are discussed and presented.
