EFFCIS
Efficient photovoltaic absorbers

EFFCIS is a BMWi (German Federal Ministry for Economic Affairs and Energy) funded project. The aim of the EFFCIS project is to improve the efficiencies of Cu(In,Ga)(S,Se)2 thin-film solar cells and modules via the improvement of the solar cell’s layers and alternative buffer layers.

To achieve higher efficiencies, it is of crucial importance to understand and improve the interfaces within the solar cell. Possible ways to improve performance that are investigated in the EFFCIS project, is the use of more transparent buffer layers than CdS (e.g., Zn(O,S) and InxSy) as well as the variation of the Ga/(Ga+In) and the S/(S+Se) ratio in the absorber layer. These changes in turn influence the interfaces within the cell, and it is important gain a detailed knowledge of the resulting changes in chemical and electronic structure.

Project period: 2020-2023
