自20世纪70年代以来，基于黄铜矿CuInSe2（CISe）的薄膜光伏太阳能电池一直备受关注。基于CISE的薄膜生长和器件制造工艺技术已经投入实际应用，并且今天可以获得商业产品。然而，在基于CISE的薄膜和器件的基础材料科学的物理和化学方面以及界面和体缺陷物理学中存在许多知之甚少的领域，有待于进一步发展。本文综述了近年来在铜硒基材料和器件的物理和化学研究方面存在的问题。铜缺乏相和碱金属的影响之间的相关性，在轻质和柔性太阳能微型模块中的应用，单晶外延Cu（In，Ga）Se2薄膜和器件，Cu（In，Ga）Se2和Ag（In，Ga）Se2材料之间的差异，宽禁带CuGaSe2薄膜和器件，具有高光伏效率的全干法处理的基于CISe的太阳能电池，以及开路电压损失分析和界面能带结构的基础研究是本文讨论的主要领域。
Chalcopyrite CuInSe2 (CISe)-based thin-film photovoltaic solar cells have been attracting attention since the 1970s. The technologies of CISe-based thin-film growth and device fabrication processes have already been put into practical applications and today commercial products are available. Nevertheless, there are numerous poorly understood areas in the physical and chemical aspects of the underlying materials science and interfacial and bulk defect physics in CISe-based thin-films and devices for further developments. In this paper, current issues in physical and chemical studies of CISe-based materials and devices are reviewed. Correlations between Cu-deficient phases and the effects of alkali-metals, applications to lightweight and flexible solar minimodules, single-crystalline epitaxial Cu(In,Ga)Se2 films and devices, differences between Cu(In,Ga)Se2 and Ag(In,Ga)Se2 materials, wide-gap CuGaSe2 films and devices, all-dry processed CISe-based solar cells with high photovoltaic efficiencies, and also fundamental studies on open circuit voltage loss analysis and the energy band structure at the interface are among the main areas of discussion in this review.
