JA Solar files patent infringement lawsuit against Astronergy
JA Solar has filed two patent lawsuits against Astronergy in the Unified Patent Court (UPC). The proceedings are related to the tunneling silicon oxide (SiO2) layers, the doped polysilicon layer, and the electrodes used in tunnel oxide passivated contact (TOPCon) solar products.
Solar cell based on ferroelectric 2D/3D/2D perovskite junction achieves 24% efficiency
The experimental device achieved an open-circuit voltage of 1.21 V, which is the highest value reported to date for highly efficient perovskite photovoltaics. The cell is based on a photo-ferroelectric 2D/3D/2D perovskite junction integrating a 2D ferroelectric perovskite single crystals in the perovskite bulk.
Runergy urges US authorities to revoke two of Trina Solar’s TOPCon patents
Runergy is pushing the US Patent and Trademark Office (USPTO) to cancel Trina Solar’s tunnel oxide passivated contact (TOPCon) patents, US9,722,104 and US10,230,009.
Rayzon Solar to expand PV module capacity to 12 GW by September 2025
Rayzon Solar currently has 4 GW of PV module manufacturing capacity and plans to add 3 GW by December, followed by another 5 GW by September 2025. This will increase its cumulative module capacity to 12 GW per year. The company also plans to build a 1.2 GW cell line by the end of 2025.
Large-scale PV has positive environmental effect on desert areas
Researchers from China found that big solar power plants have a positive positive impact on the ecological environment of desert areas. Their testing was conducted at a 1 GW solar park located in China’s northeastern Qinghai province.
Agrivoltaic community solar under development in New York state
BlueWave has started working on three agrivoltaic community solar projects in Johnstown, New York, totaling 16 MW.
MCPV moves forward with 4 GW solar cell factory in the Netherlands
MCPV, a Netherlands based cell manufacturer, has secured €4.2 million ($4.6 million) of Dutch government support for a 4 GW solar cell plant to be built in the town of Veendam. It has also obtained electricity supply commitments for initial production lines and future expansion.
Quartz crucible quality key to reducing impurities in silicon ingot manufacturing
Researchers from Norway and Germany investigated the influence of impurities in fused quartz crucibles used in silicon PV ingot production. The results suggest that the key factors influencing crucible uniformity are sand quality, sand particle size, and aspects of the manufacturing process.
Agrivoltaics for hedgerow olive orchards
Researchers in Spain have created a new model to accurately estimate oil production and energy generation in agrivoltaic facilities built in hedgerow olive orchards. The proposed approach also allows the generation of mathematical equations estimating the influence of the system design variable.
