According to the data released by the China National Intellectual Property Administration recently, the number of patent applications for solar cells in the world is 126400, ranking first in the world, with strong innovation strength.
In recent years, the average annual growth rate of patent applications in China's photovoltaic industry has reached 23.1%, and the quality of patents has also been continuously improving. Among them, Chinese enterprises have led the world in the photovoltaic conversion rate of solar cells.
Wang Shijiang, Secretary General of the China Photovoltaic Industry Association: According to our statistics, since 2014, Chinese enterprises have created the world's highest photovoltaic conversion efficiency 56 times.
Several photovoltaic companies from China are continuously setting new highs in their respective technological routes. In December 2023, Longi Green Energy broke the world record for the efficiency of single crystal silicon solar cells with a battery conversion efficiency of 27.09%. Since 2012, the photovoltaic conversion efficiency of mass-produced solar cells has increased by more than 60%, but the cost has been reduced by half. In many places, the cost of generating one kilowatt hour of electricity is only ten cents.
Nowadays, some new energy vehicle companies have begun to develop technology that combines skylights with photovoltaic power generation to power the power system inside the vehicle; Transforming the glass curtain wall of the building into a solar powered system, as well as patented technologies such as photovoltaic sand control, photovoltaic sheep farming, and photovoltaic fish farming. These patents have greatly expanded the market space for photovoltaic power generation and provided Chinese wisdom for the development of the global photovoltaic industry.
