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.
An international research group has developed an inverted perovskite solar cell with an active area of 9.6 mm2 by using polymer dipoles for interfacial engineering. It retained 96% of its initial power conversion efficiency after continuous maximum power point (MPP) tracking for 1,000 hours.
Researchers say that lightweight, high-performance perovskite solar modules could soon become competitive with crystalline PV modules in the residential segment, as such products will likely have lower manufacturing and balance-of-system costs in the future.
Italian researchers have analyzed different ways to assess the levelized cost of energy (LCoE) of perovskite solar cells and modules. They said a common approach should soon be defined to increase the market maturity of the tech.
The potential of perovskite solar cells and modules is still held back by issues such as stability and efficiency losses when scaling up from cell to module. But Annalisa Bruno, a scientist at Singapore’s Nanyang Technological University, says most of these challenges could be overcome in the near future, with this technology extending from building-integrated PV to conventional solar projects.
The US National Renewable Energy Laboratory (NREL) has achieved remarkable efficiency and stability for a wide-bandgap all-perovskite tandem solar cell. The scientist developed the device with an inverted architecture and used gas quenching instead of an antisolvent in the manufacturing process.
Scientists in Sweden have proposed the use of gold polyiodide compounds in monolithic perovskite solar cells. They built a lead-free device that achieved an efficiency of 0.052%.
Scientists in Singapore have reviewed all thermal evaporation techniques for the production of perovskite solar cells and modules. Despite limitations, the new methods could lead to high production throughputs and more efficient products.
Meyer Burger is working with several research institutes in Switzerland and Germany to integrate perovskite tandem technology into its manufacturing processes.
University of New South Wales (UNSW) researchers in Australia have discovered a low-cost way to stabilize perovskite solar cells with a triple function additive. Perovskite cells have shown the best stability results with it so far.
