Large-area graphene-perovskite solar modules with better temperature coefficient
An Italian-Greek research group has developed a large-area perovskite solar panel with graphene-doped electron transporting layers. With increasing temperatures, the module exhibits a smaller drop in open-circuit voltage than commercially available crystalline silicon panels.
Tandem tin-lead perovskite solar cell with 25.5% efficiency
The US National Renewable Energy Laboratory has made a tandem perovskite solar cell that can retain 80% of its original efficiency after 1,500 hours of continuous operation, or more than 62 days. To improve its stability, they used a hole-transporting material made of phenethylammonium iodide and guanidinium thiocyanate.
