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.The US Department of Energy's National Renewable Energy Laboratory (NREL) has developed a tandem solar cell based on two layers of perovskite. NREL claims the cell has better thermal stability and efficiency than other tandem devices based on perovskites. The researchers used ...
