An Oxford researcher has found that transparent conducting electrodes can reduce perovskite–silicon tandem solar cell efficiency by over 2%, with losses linked to electrical resistance, optical ...
The four-terminal tandem device relies on FAPbI₃ nanoparticles and a spectral splitting design, combining a 24.4% wide-bandgap top cell and a 21.5% narrow-bandgap bottom cell to reach 30.2% efficiency ...
A Chinese research team improved kesterite solar cell efficiency using potassium fluoride treatment to optimise absorber ...
