Gallium arsenide solar cell achieves 23.1% efficiency via electrochemical porosification
An international research group has utilized a new porosification technique to build gallium arsenide (GaAs) solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost thanks to the reuse of germanium.
Scientists achieve 29.9% efficiency for four-junction perovskite-CSI tandem solar cell
Achieved by scientists led by the National University of Singapore, the result is the highest efficiency ever recorded for a perovskite-CIS tandem solar cell at the research level to date. The researchers used methyldiammonium diiodide (MDADI) to reduce open-circuit voltage losses in the top perovskite cell.
