Key Highlights
•
A new molecular additive called TFMP can speed up the doping process in a key material (spiro-OMeTAD) used in perovskite solar cells, leading to better conductivity and stability. This results in solar cells that are more efficient, with a record 25.92% power conversion, and maintain over 91% of their performance after 1000 hours of operation, addressing a major hurdle for commercializing this promising solar technology.

Researchers have developed a new type of battery cathode (the positive side) that is free of expensive cobalt and uses a special surface engineering technique to create a highly stable structure. This innovation provides both high-quality surface chemistry and remarkable cycling stability, which is crucial for making cheaper, longer-lasting batteries for electric vehicles and energy storage.
