The gallium gradient in Cu (In, Ga) Se2 (CIGS) layers, which forms during the two
industrially relevant deposition routes, the sequential and co‐evaporation processes, plays …

We investigate the performance of monolithic copper-indium-gallium-selenide
(CIGS)/perovskite tandem solar cells with two different CIGS bottom device absorbers: Cu …

Theoretical calculation suggests Cu-rich chalcopyrite absorbers contain less defects and
have potential to achieve better performance than Cu-poor absorbers. However, this has not …

The selenization of Cu–Zn–Sn–S nanocrystals is a promising route for the fabrication of low-
cost thin film solar cells. However, the reaction pathway of this process is not completely …

With a record efficiency of 23.64% achieved in the past year, Cu (In, Ga) Se 2 chalcopyrites
are the absorbers of choice for thin-film solar cells. In these devices, the p-type chalcopyrite …

Ga segregation at the backside of Cu (In, Ga) Se2 solar cell absorbers is a commonly
observed phenomenon for a large variety of sequential fabrication processes. Here, we …

In polycrystalline compound semiconductor thin films, structural defects such as grain
boundaries as well as lateral stress can form during film growth, which may deteriorate their …
