Revolutionary Room-Temp Perovskite Solar Cells Boost Efficiency

• Revolutionary room-temperature-processed perovskite solar cells reach over 24% efficiency, thanks to innovative organic linker. Simplified production process with impressive results.

Researchers from UC Santa Barbara, Pusan National University, and Korea Electric Power Research Institute have developed room-temperature-processed perovskite solar cells with an efficiency of over 24%. By adding an organic linker, they were able to produce high-quality perovskite films without the need for high-temperature annealing. This innovation not only simplified the production process but also increased the material's efficiency from under 20% to 24.4%.

The team's method, which omits thermal annealing and post-treatment steps, achieved impressive efficiencies of 23.2% (24.4% with an anti-reflective coating). The new procedure is gentle and energy-efficient, making it more compatible with standard manufacturing processes. Additionally, the researchers were able to demonstrate the process by preparing a perovskite layer on fresh leaves, showcasing the potential for sustainable light energy utilization.
