Deep learning tech detects snow coverage on PV systems, calculates energy loss
Conceived by researchers in Canada, the novel method combines image processing and deep learning techniques to locate the areas of the solar panels covered with snow. It reportedly performed better than three other popular image processing-based segmentation methods.
Reliance to commercialize perovskite, back-contact HJT-IBC solar by 2026
Reliance Industries says its new energy business is developing heterojunction (HJT) bifacial solar panels with 26% efficiency, alongside plans to commercialize perovskite and HJT with interdigitated back-contact (IBC) technology within the next two years.
Fraunhofer CSP developing new patent infringement investigation methods for PV technologies
The German research institute is working on developing advanced, high-resolution material and thin film characterization methods that may become a set of simplified and rapid measurement procedures for routine use in intellectual property investigations.
Price range for US-delivered modules widens
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.
Solar module installations could hit 592 GW in 2024
BloombergNEF says the global solar industry will install 592 GW of modules this year, up 33% on 2023. The consultancy has also lowered its estimate for 2024 polysilicon production, as manufacturers are temporarily scaling back output.
Japanese researchers test 15%-efficient perovskite solar module for agrivoltaics
Japan’s Sekisui Chemical launched an agrivoltaics project in partnership with Terra, a unit of Japan-based Citizen Energy Chiba, to test the peformance of its perovskite solar cell technology and the effect of the PV system on plants.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 28.8% efficiency
Conceived by Chinese scientists, the cell was built with new surface reconstruction strategy based on the use of 1,4-butanediamine (BDA) and ethylenediammonium diiodide (EDAI2) as surface modifiers. The device was able to retain 79.7% of its initial efficiency after 550 h.
PV-driven drip irrigation system with compressed air storage
The proposed system uses compressed air to store energy, as well as for the prevention of clogging in the irrigation tubes. Two experimental systems were built and tested in China and clogging was reduced by up to 93%.
Chinese PV Industry Brief: Longi, TCL Zhonghuan raise silicon wafer prices
Longi has raised silicon wafer prices to CNY 1.15 ($0.16) for N-G10L wafers and CNY 1.30 for N-G12R wafers, while TCL Zhonghuan has increased its prices to CNY 1.15 for G10N wafers, CNY 1.30 for G12RN wafers, and CNY 1.50 for G12N wafers.
New coating prevents plant growth on underwater solar cells
The US Navy has funded Danish research on preventing biofouling while maintaining visible light transmission on underwater solar cells. The top solution uses ultra-low concentrations of nano-sized, seawater-soluble pigments. Power generation stayed close to 100% after 13 weeks underwater.
