China’s 1MW perovskite solar farm beats silicon system in industrial-scale test

A China-led research team has achieved a significant milestone in the development of perovskite solar panels, demonstrating their potential to become a cost-effective and efficient alternative to traditional silicon solar technology. The team, led by Nanjing University and comprising researchers from Canada, has developed a highly stable coating for perovskite – a thin, lightweight material that can be printed onto large surfaces. This coating effectively addresses the defects that lead to inefficient electricity generation.

The researchers' perovskite panel, measuring roughly the size of a dining table, reached an impressive 22% efficiency and produced 158.4 watts of power. Crucially, the panel demonstrated its resilience under real-world conditions, withstanding heat, humidity, and temperature extremes. In a three-month field test alongside a 3.5MW silicon system at the same solar farm, the perovskite system consistently generated more electricity, outperforming silicon by 3.42%, 3.79%, and 5.81% in March, April, and May respectively. This performance advantage grew stronger as sunlight became more intense.

The scientists' work represents a "robust, industry-ready" approach to manufacturing large perovskite solar modules and sets a new benchmark for industrial-scale production. Their findings establish that processability, durability, and efficiency can now be engineered simultaneously. The study, published in the journal Nature, marks a significant step towards making perovskite solar panels commercially viable and potentially competitive with silicon panels in the global solar industry.
