Hong Kong researchers develop inverted perovskite solar cell with 25.6% efficiency

The research team said the cell also achieved remarkable thermal stability, as it was able to retain 90% of its original efficiency for over 1,000 h. The device uses a self-assembled monolayer to stabilize the interface between the perovskite absorber and the hole transport layer.Researchers at the City University of Hong Kong (CityU) have developed an inverted perovskite solar cell based on a self-assembled monolayer (SAM) that can reportedly enhance the cell's thermal stability. Inverted perovskite cells have a device structure known as "p-i-n", in which hole-selective contact p is at the bottom ...
