On August 16, the 19th China Renewable Energy Conference was held in Xi'an. Li Zhenguo, founder and president of LONGi Green Energy, delivered a keynote speech, in-depth discussion on how new energy can create a new situation for national energy security. During the conference, the Photovoltaic Professional Committee of the China Renewable Energy Society (CPVS) released the "2024 China Highest Efficiency of Solar Cells". LONGi has a total of 6 cell efficiencies selected, and the "Ultra-High Efficiency and Low-cost Back-contact Crystalline Silicon Heterojunction Solar Cell" and "Ultra-High Efficiency Silicon-based Tandem Cell" projects were selected as "2023 Major Scientific and Technological Progress in the Photovoltaic Field".

"The amount of solar energy reaching the earth's surface each year, if converted into coal, is approximately equal to 130 trillion tons of standard coal and 300 trillion kilowatt-hours of electricity, which is greater than the sum of all other energy sources." Li Zhenguo pointed out that as the resource attributes of energy gradually shift toward manufacturing attributes, the energy security issues plaguing the world are expected to be fundamentally resolved.

According to statistics from the International Renewable Energy Agency, the global average photovoltaic electricity cost per kilowatt-hour dropped from $0.445/kWh to $0.049/kWh from 2010 to 2022. It is not difficult to see that in the past decade, the photovoltaic electricity cost has been declining significantly, and photovoltaics have brought more possibilities for energy transformation.

Li Zhenguo said that compared with the uneven distribution of fossil energy, photovoltaic power generation has a purer manufacturing attribute, which can not only ensure national energy security, but also reduce costs through economies of scale. Today, the lowest price of photovoltaic power generation has dropped to around 0.1 yuan per kWh, and the continuous improvement of the learning curve has made photovoltaic power more and more competitive. By 2050, the cost of photovoltaic power generation will be 76% lower than coal, 15% lower than onshore wind power, 73% lower than natural gas, and 71% lower than nuclear power.
