Overview
- Researchers at IIT Guwahati applied ultrathin (10–15 nm) donor–acceptor organic layers at the perovskite interface to reduce defects and control charge behaviour.
- Solar cells built on the engineered hybrid formamidinium perovskite reached a laboratory power conversion efficiency of 25.73 percent.
- Engineered devices kept about 90 percent of initial performance after ambient storage and about 75 percent under continuous thermal and light stress, indicating improved short‑term stability.
- The same FA‑based perovskite was used as a 220 nm active layer in memristors that show low‑power, multistate resistive switching and endurance characteristics suited to neuromorphic computing.
- The team has filed patents and is talking with industry partners to scale manufacturing, while independent verification and long‑term field durability remain outstanding questions.
