PV module fault detection tech based on deep learning of electroluminescence
The novel technique is based on the VarifocalNet deep-learning object detection framework, which was reportedly tweaked to achieve quicker and more accurate results. Compared to other such methods, the new approach was found to be the most accurate and third quickest.
Indian state approves 450 MW solar project along expressway
The Indian state of Uttar Pradesh has approved a 450 MW solar project along a major expressway, following the completion of a detailed project report by the Global Energy Alliance for People and Planet (GEAPP).
Monolithic perovskite-organic tandem solar cell achieves 24.27% efficiency
Researchers at City University of Hong Kong have developed a monolithic perovskite-organic tandem solar cell with a wide-bandgap subcell that reportedly provides “remarkable” stability. The tandem device achieved one of the highest efficiencies ever reported for this type of solar cell technology.
PV systems can now support grid as fossil fuels decline, says IEA-PVPS
A new report by the International Energy Agency’s Photovoltaics Power Systems Programme (IEA-PVPS) says that existing PV systems have the technical capabilities to provide various frequency-related grid services.
China’s largest electrochemical storage facility achieves grid connection
Huadian (Haixi) New Energy Co. has connected the 270 MW/1,080 MWh Togdjog Shared Energy Storage Station to the grid in China’s Qinghai province, marking the start of operations for China’s largest single electrochemical storage facility.
BII, Norfund to invest in IndiGrid’s green transmission projects
British International Investment (BII) and the Norwegian Climate Investment Fund (Norfund) say they will invest in three IndiGrid inter-state transmission system projects that are currently under construction in India.
Scientists classify weather types based on extreme photovoltaic output events
Scientists used a year’s worth of data from East China to analyze what weather conditions affect abnormal, high, and low PV output days. They also constructed a simple extreme output prediction model and examined the atmospheric circulation anomalies corresponding to extreme output events.
Ternary organic solar cell based on dimerized small molecule achieves 18.12% efficiency
A team from the Southern University of Science and Technology in China has designed a small molecule donor to act as a third component in ternary organic cells. It helped to achieve a power conversion efficiency of 18.26% when fabricated with a PM6:BTP-eC9 organic solar cell.
