Dutch consortium seeks to reduce costs of hole transport layers for perovskite solar cells
Two Dutch manufacturers have teamed with TNO’s perovskite solar cell experts to integrate spatial atomic layer deposition equipment to produce ultra-thin, high-quality nickel-oxide hole transport layers in a roll-to-roll process. The team targeting production integration in mid-2027, with full-scale production by 2030.
Replacing silver in PV manufacturing with new graphene electrode technology
Swiss-British university spinoff, GraphEnergyTech, is developing graphene electrode technology to replace silver and other metals traditionally used in solar cell manufacturing.
Gas quenching with helium, argon for more stable perovskite solar cells
Kuwait University researchers investigated the relationship between the molecular weight of the quenching gas and the morphology of perovskite films used in solar cells, finding that argon and helium extended device lifetimes compared to using the more conventional nitrogen.
Chinese scientists build 20.3%-efficient mini inverted perovskite solar modules via slot die coating
A team led by University of Electronic Science and Technology of China (UESTC) has found that pyrrodiazole as an additive in formamidinium iodide (FAI)-based inverted perovskite solar enables larger area devices made with industry-compatible slot die coating. Modules made using the technology achieved 20.3% certified power conversion efficiency and retained 94% of initial efficiency after 1,000 h in standard testing.
Power Roll developing 12.8%-efficient back-contact perovskite solar devices
Researchers from the U.K.’s University of Sheffield and Power Roll, a perovskite solar PV technology company, have achieved 12.8% power conversion efficiency in indium-free devices based on novel back-contact process. A slot-die coating process was demonstrated, compatible with roll-to-roll manufacturing.
