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.
