Solvent study solves solar cell durability puzzle

CNRS, a consortium partner in collaboration with Rice University, has contributed to solving a long-standing challenge in the field of halide perovskites: Fine-tuning of solvent and band alignment has enabled the fabrication of thick 3D/2D perovskite bilayers with 24.5% photovoltaic efficiency and exceptional stability.
This is a key advance in enabling the translation of new perovskite material compositions into stable and efficient large-scale devices.

This study was performed in collaboration with Rice University (Houston, USA), Northwestern University (Evanston, USA), Purdue University (West Lafayette, USA), Washington University (Seattle, USA), Guangzhou University (Guangzhou, China), Argonne National Laboratory (Argonne, USA.
This project has received funding from PeroCUBE European Project.
