More than 100 companies in China are now mass producing thin, lightweight perovskite solar cells, reflecting strong momentum in next generation photovoltaic technology. According to a report by Nikkei, the growing ecosystem includes major players such as CATL and BYD, alongside a wide range of emerging solar technology firms. The increasing participation of both established manufacturers and startups highlights accelerating investment in alternatives to traditional silicon based solar panels, particularly as efficiency gains in conventional cells begin to plateau.
Production capacity is expanding rapidly across multiple companies. Last year, UtmoLight launched what is intended to be a 1GW factory capable of producing around 1.8 million cells annually, achieving a conversion efficiency of 17.44 percent. Meanwhile, Hangzhou Microquanta Semiconductor Technology has already been in production for four years, operating with a 100MW annual capacity. In another significant development, Kunshan GCL Optoelectronic Materials raised $726 million last year to build a facility with a 1GW capacity, with plans to expand output to 2GW in the future. These investments underline the scale at which companies are preparing to commercialize perovskite technology.
Several other firms are also pushing forward with ambitious manufacturing initiatives. Renshine Solar is producing perovskite modules and is widely considered among the top ten producers in the segment. Hiking PV began construction of a 7GW perovskite tandem cell facility in 2023, targeting completion by late 2025. Mellow Energy is building a 100MW plant while aiming to scale to gigawatt level capacity over time. At the same time, MicroQuanta has commissioned an 8.2MW plant using its 90W perovskite panels, marking another step toward broader deployment. These projects collectively demonstrate how quickly production lines are moving from pilot stages to industrial scale manufacturing.
The shift toward perovskite technology is partly driven by the limitations of silicon solar cells, whose power conversion efficiency is approaching theoretical boundaries. Perovskite solar cells, by contrast, allow numerous combinations of materials, creating significant opportunities for further performance improvements and cost reductions. Their lightweight and flexible nature also opens possibilities for new applications beyond traditional rooftop installations, including integration into building materials and portable energy solutions. As more companies invest in scaling production and improving efficiency, China’s growing base of manufacturers is positioning perovskite solar cells as a key area of competition in the global renewable energy landscape.
