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.
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.
Solar PV flooring for residential, commercial use
Turkey-based Ankara Solar Energy launched its own brand of walkable PV flooring for residential and commercial projects. Its 30 W and 120 W square panels with anti-slip glass front covers are sold with a supportive pedestal system, and are now available for the European and U.S. markets.
U.S. solar car race success for two Canadian teams
Solar car teams from Canada outperformed in two categories of the latest Electrek American Solar Challenge. The student team from Polytechnique Montréal won first in the multiple occupant vehicle category, and the students from École de technologie supérieure won second place in the single occupant vehicle category.
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.
Chinese PV Industry Brief: Solargiga forecasts net loss for H1
Solargiga says it expects a net loss between CNY 95 million ($13.3 million) and CNY 115 million for the first half of 2024.
Tokuyama plans polysilicon factory in Vietnam
Japan’s Tokuyama says it will build a new polysilicon manufacturing facility in an industrial park in Ba Ria-Vung Tau province, Vietnam.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 28.8% efficiency
An international research team has developed an all-perovskite tandem PV device that reportedly shows reduced recombination losses in the cell’s bottom device and remarkable stability. To improve the perovskite solar cell’s surface, the scientists created partially non-conductive and non-functional areas that protect the perovskite area underneath from becoming defective.
Global solar module prices fall amid weak demand
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
