Japanese scientists have developed solar panels made from perovskite metals that offer 40% efficiency in converting sunlight into electricity. In comparison, traditional crystalline silicon solar panels have an efficiency of 15% to 30%. The Japanese company Sekisui will soon begin commercial production of these perovskite solar panels.
These panels are cheaper to produce than silicon ones, easier to manufacture, and generate more electricity even in low sunlight or rainy conditions. Their flexibility allows them to be installed on walls, car roofs, and virtually any surface.
The Japanese government aims to generate 20,000 megawatts of electricity over the next five years by installing these panels on government buildings, rooftops, open fields, and vehicles.
China is expected to become a global leader in perovskite solar panel production due to its abundant resources of tin and lead. Chinese companies are also producing solar panels with 39% efficiency by combining silicon and perovskite materials, potentially revolutionizing solar energy.
