The researchers created solar panels that work better and last longer by solving a hidden problem in an innovative type of solar cell, reported Xplore Technology.
This exciting development comes from an international team led by the University of Surrey in the UK, who have cracked the code for making more efficient solar cells using a material called perovskite. These improved cells can convert an impressive 23% of sunlight into usable electricity while having a lifespan 66% longer than previous versions, according to a study published in the journal. Energy and environmental sciences.
The research team focused on understanding and solving a previously unknown problem causing these promising solar cells to degrade over time. Their solution? Added a special ingredient that stops unwanted chemical reactions, helping cells maintain peak performance much longer.

Perovskite solar cells represent the next evolution in solar technology. While traditional silicon panels help millions of homeowners reduce their energy billsthese new perovskite panels could work even better while costs less.
“This advancement is a major step toward high-efficiency, sustainable solar panels that will give more people access to clean, affordable energy while reducing dependence on fossil fuels and global carbon emissions,” Hashini said Perera, the study’s lead author, told Tech Xplore. .
The implications for homeowners are enormous. More efficient and longer-lasting solar panels mean greater savings on electricity bills over time.

Professor Ravi Silva, who heads the university’s Institute of Advanced Technology, put it best: “This research brings us closer to panels that not only generate more energy over their lifetime, but that also last longer. Greater efficiency and fewer replacements mean more green power with less energy. waste.”
The team doesn’t stop there. They are working to further refine these materials and processes, to achieve even higher performance. The University of Surrey is building a 12.5 MW solar farm to test these panels in real-world conditions.
