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.
Flexible indoor perovskite solar cell achieves 32.5% efficiency
Italian scientists have developed a flexible indoor perovskite solar cell with 32.5% efficiency. Their design uses a PET substrate combined with a tetrabutylammonium bromide layer over the perovskite absorber. This additional layer effectively reduces defect density and enhances the stability of the underlying 3D perovskite structure.
Tandem perovskite-silicon solar cells retained 80% of efficiency after 1 year
Saudi Arabia researchers claim to have improved the outdoor stability of a tandem perovskite-silicon solar cell by using proper encapsulation. By the end of the first year of operation, the cell’s fill factor remained above 70%.
UNIST, EPFL claim 25.6% efficiency world record for perovskite solar cell
Scientists have set a new efficiency record for a single-junction perovskite solar cell at 25.6%. The cell additionally showed operational stability for 450 hours, and intense electroluminescence with external quantum efficiencies of more than 10%.
