Summary
The development of high-efficiency, low-cost, and environmentally friendly next-generation photovoltaic technologies is critical to reach carbon neutrality goals. Thin film solar cells have attracted tremendous attention in view of their lightweight characteristic and the compatibility with flexible and curved substrates, showing broad prospects for wearable devices, building-integrated photovoltaics (BIPVs), space applications, etc. In the past decades, the rise of emerging chalcogenide semiconductors and film processing technologies has opened up new frontiers for the development of high-efficiency next-generation thin film photovoltaics.
The aim of this Special Issue is to present the current state of the art in emerging chalcogenide absorbers as well as advanced film processing for thin-film photovoltaics. We hope to bring together recent advances in the development of novel chalcogenide materials, the characterization and optimization of their structure-property-performance relationships, strategies for device optimization and integration, advanced characterisation techniques, etc. We invite authors to contribute original research articles and review articles.
This Special Issue includes but are not limited to the following topics:
· Development of novel chalcogenide absorbers
· Advanced characterization of chalcogenide materials and devices
· Device physics of chalcogenide-based solar cells
· Device simulation and computations of chalcogenide-based solar cells
· Sb2S3, Sb2Se3, CZTS, CIGS, CdTe, Se and other chalcogenide absorbers
· Chalcogenide semiconductors for indoor photovoltaics
