State-owned power generation company China Huadian Corporation has begun work on a 3.3GW solar site in Sichuan province. The project is one of nine renewable energy plants listed in China’s latest national five-year plan.

The cell may be potentially used as a top subcell in tandem crystalline silicon-based devices. It was built with CdSe thin film with a direct bandgap of 1.72 eV.

Wood Mackenzie has predicted solar equipment cost increases will ease back after last year saw the average cost of solar electricity rise for the first time in the Asia-Pacific region.

Developed by scientists in China, the cell achieved an open-circuit voltage of 1.192V, and a fill factor of 80.67%. Its perovskite capping layer was treated with a special ionic liquid that had a positive influence on both the device’s efficiency and stability.

Sungrow is a market leader in the manufacture of PV inverters. The Chinese giant is also increasingly focused on the supply of energy storage systems and how these can be best coupled with inverters for improved performance. pv magazine caught up with Jack Gu, Senior Vice President of Sungrow to understand how the manufacturer has dealt with the recent solar supply chain challenges and what the company’s focus is on going forward.

Solar manufacturer JinkoSolar announced on Wednesday that its 8 GW TOPCon cell factory in the Anhui Province has started manufacturing activities. Polysilicon supplier and solar cell maker Tongwei announced on Thursday it expects to achieve a net profit of up to RMB 8.5 billion ($1.33 billion) with a YoY increase of around 136%.

Built by the Chint Group, the project is currently the largest in China combining PV power generation and fish farming. It is located in Wenzhou, a city with a subtropical maritime monsoon climate in China’s Zhejiang province.

Finland-headquartered Sumitomo SHI FW has entered a collaboration with China’s Shanghai Power Equipment Research Institute to evaluate the feasibility of long-duration energy storage using liquefied air energy storage technology.

Chinese scientists have developed a hybrid cooling technique to reduce module temperatures by up to 12.86 C and increase power yields by 7.25%. Their system features a PV module and a separate RC module, integrated with a flat plate heat pipe in between.

The energy company will buy panels from JinkoSolar, Risen Energy, Canadian Solar, JA Solar, GCL Integration and Longi. Elsewhere, Xinyi Solar and Golden Solar have both announced new transactions to strengthen their business.
