A Full-Size Perovskite Solar Panel Reaches 22% Efficiency and Passes Reliability Tests

A 0.72-square-metre perovskite solar module achieved a certified 22% total-area efficiency and passed the IEC 61215 qualification sequence. The result tackles two persistent barriers to commercial perovskite panels, scale and durability, but accelerated tests and a three-month field comparison cannot yet prove decades of service.
