Paper: Complex Interplay between Absorber Composition and Alkali Doping in High-Efficiency Kesterite Solar Cells

Title: Complex Interplay between Absorber Composition and Alkali Doping in High-Efficiency Kesterite Solar Cells Authors: Stefan G. Haass,* Christian Andres, Renato Figi, Claudia Schreiner, Melanie Bürki, Yaroslav E. Romanyuk, and Ayodhya N. Tiwari Link (Open Acess): Adv. Energy Mater. 2018, 8, 1701760 Abstract: Sodium treatment of kesterite layers is a widely used and efficient method to boost solar cell efficiency. However, first experiments employing other alkali elements cause confusion as reported results contradict each other. In this comprehensive investigation, the effects of absorber…

Review of the STARCELL project publications

This project is developed in the European Union due to photovoltaics is one of the main technologies necessary to achieve the targets of EU Energy Roadmap 2050.  For me, it is interesting to know the state of the art of this material as a prospect for a postdoctoral stay in 2019-2020. This topic is highly related to solar cell development and innovation. One key feature is the development of thin film photovoltaics using flexible substrates Webpage Snapshot (April 22nd, 2019)…
