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.
Physics-based model to predict soiling losses in bifacial solar modules
Scientists in India have developed a novel way to predict soiling accumulation on bifacial modules. Their approach considers dust deposition, rebound, and resuspension phenomena.
With China PV modules reaching record low prices, is there a chance for local PV manufacturing elsewhere?
From the International Solar Energy Society’s perspective, and the vision of a world with 100% renewable energy for everyone used wisely and efficiently, PV module production should not become an oligopoly and should not be concentrated in one corner of the world.
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.
Falling module prices to drive record ‘16 GW’ solar addition this fiscal
Softening of PV module prices will improve investment returns for 45 GW of solar projects in the pipeline that have been awarded since FY 2021. This, in turn, will spur project development, with around 16 GW capacity estimated to be installed this fiscal.
