In 2023, 370 GW of photovoltaic capacity will be installed, annual polysilicon supply will see surplus

By the end of 2022, the global polysilicon production capacity was 1.21 million mt, and the polysilicon output was around 900,000 mt. Based on the silicon consumption of 2.5g/w per watt and a 1.2 photovoltaic capacity ratio, the polysilicon output can service photovoltaic installed capacity of around 300 GW. There is already a slight surplus in polysilicon supply, and the oversupply is expected to intensify in the fourth quarter of 2022.

In 2023, the global polysilicon production capacity will reach 2.51 million mt, and the output is expected to be 1.53 million mt. Based on the silicon consumption per watt of 2.4g/w (technical progress) and a 1.2 photovoltaic capacity ratio, the polysilicon output can service photovoltaic installed capacity of 530 GW. The global installed capacity of photovoltaic is expected to be 370 GW in 2023, leading to severe oversupply of polysilicon.

[SMM PV Express] Over 28%! Perovskite-Organic Tandem Solar Cell Efficiency Breaks Record.

A research team from the Institute of Chemistry, Chinese Academy of Sciences (hereinafter referred to as ICCAS) has boosted the power conversion efficiency of perovskite-organic tandem solar cells to 28.04%, once again setting a new world record for such devices. The related research was published in *Nature* on July 13. The corresponding author of the paper, Li Yongfang, an academician of the Chinese Academy of Sciences and a researcher at ICCAS, stated that perovskite-organic tandem solar cells combine the advantages of light weight, flexibility, and high specific power. They can be widely applied in ground-based scenarios such as buildings, transportation, and wearable electronic devices, and can also play a positive role in space fields including satellites, space stations, and deep-space exploration, serving as a vital energy guarantee for humanity’s march into space. "This kind of cell is thin, lightweight, and portable; it can easily be placed in a backpack and carried around. During outdoor trips, you simply unfold it to charge electronic devices like mobile phones," Li Yongfang told *China Science Daily*.
