TÜV offers guidance on plug-in balcony solar panels
Balcony solar modules are becoming increasingly popular. TÜV, a technical inspection association in Germany, has come up with tips to safely install and operate them.
High hopes for heterojunction
In recent months, China’s Risen Energy has posted impressive module efficiencies, closing in on 24%, with its hyper-ion series. The company will ramp up to large-scale production of these heterojunction products in the first half of 2023, and pv magazine recently caught up with Risen Energy’s Chief Information Officer Terry Wu to discuss this, as well as the company’s work on energy storage projects.
3D/2D perovskite solar cell treated with substituted PEAI hits 23.08% efficiency
An international research team has fabricated a quasi-2D perovskite solar cell with a special kind of phenethylammonium iodide (PEAI) salt to enhance hole extraction. The result is a 23.08%-efficient device that is also able to retain 95% of its initial efficiency after 900 hours.
Biden to maintain US solar tariff pause with veto
US legislators are moving to restore tariffs for the shipment of solar components from four major Southeast Asian nations, but US President Joe Biden will veto the move and maintain the pause on tariffs.
Scientists compare PVsyst, Comsol software in assessments of bifacial PV
Spanish researchers compared two software programs that are used to analyze bifacial PV systems. They found that PVsyst outperformed Comsol in calculating solar production in nearly all cases.
Concentrating photovoltaics for agricultural applications
A research team has studied the potential of using concentrating photovoltaics in agriculture and found that it offers advantages in terms of energy yield and de-shading compared to conventional photovoltaics. However, the higher costs must be carefully considered.
Novel technique to recover 100% of silver from CIGS solar cells
Swedish researchers have developed a method to recycle valuable metals from flexible thin film copper-indium-gallium-diselenide (CIGS) solar cells under mild leaching conditions. They showed that 100% of silver and 85% of indium can be recovered after 24 hours of leaching at room temperature using two moles of nitric acid.
GCL System Integration unveils 585 W TOPCon solar panel with 22.6% efficiency
The Chinese manufacturer is offering six versions of its new TOPCon modules, with power outputs between 560 W and 585 W. The power conversion efficiency ranges from 21.7% to 22.6%.
Initial attempt to build thin-film solar cells from molybdenum disulfide
A team at Colorado State University has proposed making thin-film solar cells from naturally abundant molybdenum disulfide. It has conducted a series of experiments to show that extremely thin films of molybdenum disulfide have unprecedented charge carrier properties.
Polysilicon prices fall 1.33% to six-week low of $37.218/kg
