本研究探讨了不同的方法，以提高产生的电流密度在Cu（In，Ga）Se 2（CIGSe）为基础的太阳能电池下降到0.1 μm的潜力。先进的光子管理，包括吸收增强和反射减少的吸收体，进行了研究。在这方面的贡献，使用的三种主要方法是：-CIGSe厚度的减少，通过化学蚀刻结合厚度减少和平滑效果的吸收体。- 通过前接触工程和通过从Mo层“剥离”CIGSe层来替换后接触以及沉积新的反射后接触的光学管理。- 等离子体激元结构在CIGSe太阳能电池中的应用，使得能够在亚波长尺度下进行光限制。
This study addresses the potential of different approaches to improve the generated current density in ultrathin Cu(In,Ga)Se2 (CIGSe) based solar cells down to 0.1 μm. Advanced photon management, involving both absorption enhancement and reflection reduction in the absorber, is studied. In this contribution, the three main approaches used are: - The reduction of the CIGSe thickness by chemical etching which combines thickness reduction and smoothing effect on the absorber. - Optical management by front contact engineering and by the replacement of the back contact by the "lift-off" of CIGSe layer from the Mo layer and the deposition of a new reflective back contact. - Application of plasmonic structures to CIGSe solar cells enabling light confinement at the subwavelength scale.
