Saudi Arabia\u2019s King Abdullah University of Science and Technology (KAUST) has developed an innovative method that significantly improves the efficiency and stability of solar cells, reported the Saudi Press Agency on Tuesday.<\/p>\n\n\n\n
The breakthrough was made through KAUST\u2019s international team of scientists in collaboration with the Fraunhofer Institute for Solar Energy Systems (ISE) and the University of Freiburg.<\/p>\n\n\n\n
The achievement is based on treating the surface of perovskite in perovskite\u2013silicon tandem solar cells with a single molecule and is expected to help countries adopting solar energy save billions of dollars.<\/p>\n\n\n\n
Using the technique, the tested solar cells achieved a conversion efficiency of 33.1% and a record open-circuit voltage of 2.01 volts, both key indicators of solar cell performance.<\/p>\n\n\n\n
The treated devices also maintained their enhanced output during operation on the Saudi coast at temperatures above 40\u00b0C for more than 1,500 hours.<\/p>\n\n\n\n
This efficiency underscores the industry\u2019s strong investment in perovskite\u2013silicon tandem solar cells compared with conventional silicon cells, whose physical efficiency limit does not exceed 30%.<\/p>\n\n\n\n
Combining a perovskite cell with a silicon cell in a tandem design enables the optimal utilization of the solar spectrum, allowing for greater energy capture from sunlight.<\/p>\n","protected":false},"excerpt":{"rendered":"
