Thin-film solar cells based on Cu(In,Ga)Se2 (CIGS) absorbers have achieved conversion efficiencies close to 23%. Such a high performance could be reached by incorporating heavy alkali elements into the CIGS absorber using an alkali fluoride post-depo

The presence of Ge during the synthesis of thin film kesterite Cu2ZnSnSe4 (CZTSe) solar cell absorbers boosts their power conversion efficiency, especially due to an improved open circuit voltage. The mechanism underlying this beneficial effect of Ge

Highly performing kesterite-based Cu2ZnSn(S,Se)(4)(CZTSSe) thin-film solar cells are typically produced under Cu-poor and Zn-rich synthesis conditions. However, these processing routes also facilitate the formation of secondary phases as well as devi

Thin film solar cells based on Cu-poor Cu(In,Ga)Se2 absorbers grown by a three-stage co-evaporation process have been shown to strongly benefit from a Cu-rich intermediate growth stage and the presence of alkali elements such as Na, K, and Rb, pushin

Solar cells based on Cu(In,Ga)Se absorbers are the most efficient ones among all thin film photovoltaics. The current world record efficiency was attained by applying a rubidium fluoride (RbF) post deposition treatment (PDT) to the absorber. However,

The Cu-poor phases Cu(In,Ga)(3)Se(5 )and Cu(In,Ga)(5)Se-8 play an important role both for understanding the Cu-(In,Ga)-Se material system and for growing high-efficiency Cu(In,Ga)Se-2 thin film solar cells. Using extended X-ray absorption fine struct

The efficiency of kesterite-based solar cells is limited by various non-ideal recombination paths, amongst others by a high density of defect states and by the presence of binary or ternary secondary phases within the absorber layer. Pronounced compo
