Imec presents inverted perovskite solar cell with 24.3% efficiency
The researchers of the Belgian research institute used a dual-layer treatment for the perovskite absorber, which they said improved the cell efficiency and stability. The device achieved an open-circuit voltage of 1.17 V, short-circuit density of 24.5 mA/cm2, and a fill factor of 84.6%.
Australian team claims 99% recovery rate with solar recycling process
Engineers at the University of New South Wales (UNSW) have developed a new, more effective method to recycle end-of-life solar panels. The technique allows them to quickly and efficiently separate 99% of PV cell component materials.
Novel approach to build bismuth trisulfide thin-film solar cells
Researchers in Estonia applied for the first time the close-spaced sublimation (CSS) deposition technique to manufacture solar cells based on bismuth trisulfide (Sb2S3). The resulting devices showed limited power conversion efficiency so far, but the scientists claim the new process paves the way for the development of future earth-abundant inorganic PV materials.
Fraunhofer ISE unveils 15.8%-efficient organic solar cell
Germany’s Fraunhofer ISE has achieved a world record efficiency for organic cells at the lab level. It now aims to bring the PV technology to market maturity.
Chinese PV Industry Brief: JinkoSolar’s H1 panel shipments hit 30 GW
JinkoSolar says that its solar panel shipments reached 30 GW in the first of this year.
High voltage mini solar panel converts laser light into electricity
US scientists developed a monocrystalline solar panel relying on “minicells” based on polysilicon on silicon oxide passivating contacts. The module works with laser light and can reportedly achieve a photoconversion efficiency of over 40% and an open-circuit voltage of 7 V.
NREL develops perovskite solar cells with 93% bifaciality
The National Renewable Energy Laboratory (NREL) has made highly bifacial perovskite cells with a front-side efficiency of 23%.
France recycled 3,800 tons of solar modules in 2022
French eco-organization Soren, which collects and recycles end-of-life solar panels, has published its 2022 annual report. Last year, more than 10 million solar panels were put on the market in France, up 25% from 2021.
2D/3D perovksite solar cell with record-breaking efficiency of 25.32%
A Chinese-Swiss research group has fabricated a 2D-3D perovskite solar cell with a world-record power conversion efficiency. The cell uses a 2D perovskite layer at the interface between the perovskite and the hole transport layer, which the researchers said can improve charge-carrier transport/extraction while suppressing ion migration.
European solar manufacturers secure EU financial support
Norsun and Midsummer have both secured financing to support their capacity expansion plans. Norway’s Norsun plans to raise its polysilicon capacity to 3 GW and Midsummer wants to build a 200 MW module facility in Sweden.
