quantum dot solar cell

Researchers in Iran have identified new ways to design perovskite quantum dot solar cells via a series of simulations. They investigated, in particular, how the perovskite absorbers can be gauged in order to enhance their electro-optical properties.

Scientists in Korea have investigated performance degradation in quantum dot solar cells – an important consideration for a technology that has seen rapid efficiency increases in recent months. The group found surface oxidation of quantum dot material represents a significant threat to longer-term performance and the researchers suggest that an additional layer in the cell could solve the problem.

South Korean scientists have produced an organic, hybrid-series tandem PV device that combines quantum dots and organic bulk heterojunction photoactive materials. They claim that the cell has the highest efficiency among all reported colloidal quantum dot cells, including single-junction devices and tandem devices.

Scientists at Australia’s University of Queensland have set a new world efficiency record for a quantum dot solar cell. The group fabricated a 0.1cm² device from a perovskite material and measured power conversion efficiency at 16.6%. The record has been verified by the United States National Renewable Energy Laboratory.
