- Swiss EPFL and the US NWU researchers reach 25.3% efficiency in perovskite cells.
- 3-mercaptopropionic acid improves contact between perovskite and substrate.
- This innovation prevents clumping of molecules by breaking carbazole clusters.
- These cells maintain 95% performance after extreme temperature and humidity.
