Novel cadmium telluride solar cell design with potential efficiency of 31.82%
Scientists in Bangladesh designed a cadmium telluride solar cell with upper/top and back contact materials made of aluminum (Al) and nickel (Ni). The device reportedly showed a quantum efficiency of around 100 % at visible wavelengths.
Fraunhofer ISE presents silicon carbide string inverter for medium-voltage applications
Fraunhofer ISE researchers claim the new silicon carbide inverter is technically able to handle voltage levels of up to 1,500 V at 250 kVA in utility scale solar power plants.
Hong Kong researchers develop inverted perovskite solar cell with 25.6% efficiency
The research team said the cell also achieved remarkable thermal stability, as it was able to retain 90% of its original efficiency for over 1,000 h. The device uses a self-assembled monolayer to stabilize the interface between the perovskite absorber and the hole transport layer.
Europe may go back to ‘normal’ inventory levels by June 2024
pv magazine recently spoke with Bartosz Majewski, CEO of Menlo Electric, a Poland-based solar distributor operating in Europe, about high inventory levels of solar panels in Europe.
Large-area perovskite-silicon tandem PV cell hits record efficiency of 25.1%
US scientists have achieved a breakthrough in PV cell tech by creating a 24 cm2 perovskite-silicon tandem solar cell. It positions a lithium fluoride interlayer between a hole transport layer and the perovskite absorber to reduce shunting losses.
