How to Make over 20% Efficient Perovskite Solar Cells

In a recent method paper published in Chemistry of Materials, HyPerCells members Christian M. Wolff, Martin Stolterfoht, Nga Phung and workgroup leaders Steve Albrecht, Dieter Neher and Antonio Abate
together with the renowned scientists Michael Saliba (Adolphe Merkle Institute) and Juan Pablo Correa-Baena (Massachusetts Institute of Technology) provide detailed descriptions and explanations on how to achieve highly efficient perovskite tandem solar cells on varios device architectures. The joint publication also underlines the excellent connection between the HyPerCells graduate school and other leading scientists and research institutes worldwide.

HyPerCells Fall Retreat 2017

The HyPerCells graduate school meets for the fall retreat 2017 in Akademie Schmöckwitz on October 11.-12. The retreat offers the possibility for members of the graduate school as well as guests to present their recent research results. This not only exchanges know-how and experiences but also promotes synergies between researchers from different fields of perovskite research.

21.4 % Record Efficiency Realised

Perovskite solar cells with record efficiencies of over 20 per cent have been realised by Christian Wolff and Martin Stolterfoht. Following their publication in the journal Energy & Environmental Science they were able to push the solar cell performance up to 21.4 % power conversion efficiency which is the highest value reported so far for "inverted" perovskite solar cells with undoped contact layers.
