A treatment of CuInS2 (CIS) based on rapid thermal processing (RTP) selenization is developed, aiming at tuning the absorber's band gap grading using the [Se]/([S] + [Se]) composition. X-ray photoelectron spectroscopy and X-ray fluorescence analysis

The surface properties of CuInS2 (CIS) thin-film solar cell absorbers are investigated by a combination of electron and soft X-ray spectroscopies. Spatially separated regions of varying colors are observed and identified to be dominated by either CuS

In this letter, we report externally confirmed total area efficiencies reaching up to 12.9% for CdS/Cu(In,Ga)S2 based solar cells. These are the highest externally confirmed efficiencies for such cells. The absorbers were prepared from sputtered meta

Reactive sputtering is an option to further reduce costs associated with the deposition of the transparent front contact for chalcopyrite-based solar modules. Our approach here is to develop a proof of concept for a ZnO window, where the i-ZnO and th

Rapid thermal sulfurization of metallic precursors has proven to be a successful method for the preparation of Cu(In,Ga)S 2 based solar cells. However, during the sulfurization, several problems can be encountered. Due to the difference in reaction r
