As of mid-2025, commercial N-type TOPCon cells reach about 23–24% efficiency, with best mass-produced TOPCon modules at 23.8% and JinkoSolar reporting 26.4% cell efficiency in tests. Heterojunction (HJT) solar cells regularly reach 25%+ efficiency in production, with Longi reporting a 27.3% lab cell efficiency. Perovskite–silicon tandem cells have surpassed 33% efficiency in labs (Longi 33.9%,…

Thermoradiative energy generation, nicknamed night-time solar, produces electricity by emitting infrared radiation to the cold night sky when the device is warmer than its surroundings. Unlike conventional solar cells that absorb sunlight, thermoradiative devices emit photons to space, effectively running as a solar cell in reverse and using the Earth–space temperature difference at night. In…
