Midsummer develops 24.9% efficient 4T tandem perovskite-CIGS solar cell
Midsummer and researchers from the University of California, Los Angeles (UCLA), say that their new tandem PV cell is suitable for the company’s Duo production equipment, which makes 56 mm x 156 mm CIGS cells on a flexible stainless steel substrate.
Semi-transparent organic photovoltaics for greenhouse applications
Scientists from the University of California, Los Angeles (UCLA), have used an antioxidant known as L-glutathione as an interlayer in an organic PV cell to prevent other materials from oxidizing. The cell has an efficiency of 13.5% and an average visible transmittance of 21.5%. The researchers said it is suitable for applications in solar greenhouses.
TOPCon shingle solar cell achieves 22.0% efficiency via thermal laser separation
Scientists from Germany’s Fraunhofer ISE and US panel maker Solaria have applied thermal laser separation and post-metallization passivated edge technology to tunnel oxide passivated contact (TOPCon) cell production. They have developed shingle PV devices that are more efficient than cells built with conventional laser scribing and mechanical cleaving methods.
Honda reusing vehicle fuel cells to build 500 kW stationary fuel cell system
Honda has revealed that it is testing a pilot stationary fuel cell stationary power system in California.
SEG Solar releases 580 W TOPCon solar modules with 22.45% efficiency
California-based SEG Solar says its new panels have a temperature coefficient of -0.30% per degree Celsius. They come with a 30-year power output guarantee for 87.4% of the initial yield.
Trina Solar unveils TOPCon solar panel series for rooftop PV
Trina Solar says its new TOPCon solar panel combines a double-glass design with n-type technology. Its efficiency ranges from 20.8% to 22.3% and the power output is between 415 W and 445 W.
Inverted perovskite solar cell achieves 23.9% efficiency, high durability
A U.S.-Canadian group of scientists used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.
U.S. scientists improve photoresponsivity in solar perovskite by 250%
Researchers led by the University of Rochester claim to have increased the photoresponsivity of a lead-halide perovskite for solar cell applications by 250%. They created a perovskite film with a plasmonic substrate made of hyperbolic metamaterial and characterized it with transition dipole orientation.
Sodium aluminum battery for renewables storage
U.S. researchers have designed a molten salt battery that uses an aluminum cathode that charges quickly and reportedly enables longer-duration discharge.
Solar may cover the world’s electricity demand with 0.3% of its land area
An international research group claims that raw materials and land availability do not present a real barrier for a global energy system with solar at its center. They said that forecasts for PV growth should not have their axis on utility-scale power plants and instead consider vertical PV, agrivoltaics, and floating PV as the source of future big market volumes.
