Novel bifacial flexible PV cell offers 27% efficiency
Scientists have simulated dozens of electron transport layer-free cell structures and have identified the optimal design with a Zr:In2O3 front transparent electrode, a CuSCN hole transport layer, and a NAN rear transparent electrode. They have also optimized its thickness and bandgap.
Unlocking untapped storage potential for Germany’s energy transition
Germany’s energy transition is making significant progress. In the first half of 2024, renewables made up 57% of the electricity mix, and this is straining the grid. Battery storage systems and optimized redispatch procedures could help integrate renewables and ease congestion, but challenges remain, says Benedikt Deuchert of Kyon Energy.
US deploys 12 GW of utility-scale solar in H1
The US Energy Information Administration (EIA( says 20.2 GW of electricity generation capacity was added in the United States during the first half of 2024. Solar energy led the way, with significant deployments in energy storage as well.
Australia needs 126 GW of solar, wind by 2030 to hit net zero by 2050, says BNEF
Australia can still reach its net-zero energy goal by 2050, according to BloombergNEF (BNEF), but there is no time to waste, with a need for significant investments in solar, wind, and energy storage to stay on track.
Porsche takes majority stake in Varta’s battery production unit
Sports car manufacturer Porsche has agreed to acquire a majority stake in Varta’s V4Drive Battery GmbH subsidiary, providing fresh cash to the embattled battery maker.
US module manufacturers seek ‘critical’ retroactive tariffs
Led by First Solar and Qcells, US solar module manufacturers have filed allegations with the US Department of Commerce, citing “critical circumstances” and suggesting increased module imports due to their previous lawsuit filings.
Getting lightweight, flexible, semi-transparent PV from lab to fab
German research group Helmholtz Association hopes to speed up the adoption of flexible printed solar PV technologies by transferring advances in the lab to industry through its growing Solar TAP initiative.
Researchers use artificial neural networks to optimize PV tilt angles
Scientists have tested several machine-learning algorithms to predict the optimal tilt angle (OTA) of solar projects in 37 Indian cities, leading to improvements of up to 90%.
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).
