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
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.
Mobile solar system for farms
India’s Vivasvan Solar has designed a foldable solar structure mounted on a trolley. The system has mechanisms to prevent damage to the panels during transit and is especially useful for agricultural farms.
Das Solar claims record open-circuit voltage of 730 mV for n-type solar cell
Das Solar has achieved a world-record open-circuit voltage of 730 mV for an M10 n-type tunnel oxide passivated contact (TOPCon) solar cell, with a power conversion efficiency of 26.24%, according to the Chinese Academy of Sciences Institute of Electrical Engineering.
