An international group of scientists has fabricated an inverted perovskite solar cell that claims both high power conversion efficiency and a promising high degree of stability. A champion cell achieved a power conversion efficiency of 25.3%, with an encapsulated version retaining 95% of the initial efficiency after extensive heat and humidity testing. 

Daqo says it has postponed its polysilicon expansion plans in China’s Inner Mongolia region, while JinkoSolar says it delivered 55.7 GW of PV products in the first three quarters of this year.

Belgium’s Innoptus Solar Team was the first car to cross the finish line this week in the 3,000 km Bridgestone World Solar Challenge. The team beat its 2019 winning time by 48 minutes.

China deployed 128.94 GW of new solar power in the first nine months of 2023, with 15.78 GW added in September, bringing its cumulative capacity to 525 GW, according to the National Energy Administration (NEA).

On the journey from Darwin to Adelaide, the Innoptus Solar Team, a non-profit project of students from the University of Leuven, is in a leading position amongst dozens of competitors from around the world in the Bridgestone World Solar Challenge. It tapped European research labs for PV equipment and know-how.

Sunrev says it plans to build a vertically integrated cell and module facility in Xining, in China’s Qinghai province.

US-based Creighton University has equipped a new student residence with solar heat collectors generating an annual peak capacity of 69.9 kW thermal energy. The VirtuHOT HD system, conceived for rooftop applications, includes an absorber plate, a borosilicate glass tube, and an integrated mounting system.

To perform a wide range of tests on new types of PV modules under realistic conditions, EKO Instruments has introduced PV Blocks, an expandable all-in-one type of system  with capacity for up to 32 modules. It is targeted at research labs, module manufacturers, and testing organizations. 

Sweden-based Epishine has launched a developer kit based on its 6-cell 50 mm x 50 mm organic PV module for prototyping and testing its use in battery-free indoor sensing and monitoring devices.

TCL Zhonghuan has raised funds to build a polysilicon and cell factory, while Haitai Solar has changed the location of its 10 GW TOPCon factory from Yancheng, Jiangsu province, to Chuzhou, Anhui province.
