Cadmium-doped perovskite solar cell achieves 22.7% efficiency
A Chinese-Canadian research group has utilized for the first time a cadmium iodide doping technique to stabilize the blade coating process in the manufacturing of solar cells based on formamidinium lead iodide (FAPbI3) perovskite. The academics built a cell showing a considerable increase in efficiency compared to an identical device without cadmium doping.
Air-processed perovskite solar cell with 18.3% efficiency
The methylammonium-free perovskite solar cell was fabricated through a deposition technique that is claimed to reduce by around 30% the use of solvents during the perovskite deposition. The estimated overall cost of the proposed synthetic process is around €0.025 per cell.
