Longi Solar panels, the largest solar panel manufacturer in the world, achieved a new record for energy conversion efficiency in solar cells with heterojunction technology (HJT). The new efficiency, which is 25.82%, has been confirmed by the German Institute for Solar Energy Research (ISFH).
This happens while about 5 months ago, Longi Solar panels Company achieved a record efficiency of 25.09% for the double-sided n-type monocrystalline solar cell based on TOPCon technology. These consecutive successes indicate the impressive speed in the development of the photovoltaic solar energy industry in the world.
Longi Solar panels is one of the largest manufacturers of photovoltaic solar panels in the world, which invests more than 5% of its annual income in research and development. It is worth mentioning that Longi Solar panels was introduced as the world's best-selling solar panel by selling 24.5 gigawatts of solar panels in 2020. This Chinese solar panel production company plans to increase its photovoltaic panel production capacity to 65 GW by the end of 2021.
