稀土富铜锌锡硫化物(CZTSSe)是开发低成本、可持续发展的薄膜太阳能电池的重要材料。介绍了利用CZTS纳米晶的硒化制备CZTSSe太阳电池的方法。通过调整CZTS纳米晶的组成和开发一种坚固的薄膜包覆方法，在AM 1.5照明和光浸泡下获得了高达7.2%的总面积效率。
Earth abundant copper-zinc-tin-chalcogenide (CZTSSe) is an important class of material for the development of low cost and sustainable thin film solar cells. The fabrication of CZTSSe solar cells by selenization of CZTS nanocrystals is presented. By tuning the composition of the CZTS nanocrystals and developing a robust film coating method, a total area efficiency as high as 7.2% under AM 1.5 illumination and light soaking has been achieved.
