Chinese researchers have demonstrated a single-step submicron structured surface texturing process that improved the absolute efficiency of a TOPCon solar cell by 1% through broadband anti-reflection and lower electrical resistance. The cell-level performance was validated in laboratory and outdoor tests.

French researchers have developed a high-resolution computational framework to model microclimate effects of large floating solar PV systems, enabling accurate predictions of heat transfer, ambient temperatures, and water evaporation based on panel configuration and wind conditions. The model can inform thermal performance, environmental impacts, and optimize designs for utility-scale floating PV, as well as ground-mounted and agrivoltaic installations.

The UK-based perovskite solar PV specialist has announced a new metrology research project with Swansea University and a new development agreement with Renolit, a German plastic films, sheets and polymer solutions company.

Researchers in South Korea improved the performance of tin monosulfide (SnS) solar cells with a potassium fluoride-assisted post-treatment and a vapor transport deposition process. The treated solar cells had a power conversion efficiency of 4.10% and reduced recombination sites, compared to 3.42% for untreated devices.

Researchers at Hebrew University of Jerusalem have demonstrated 9.2% efficient printable semi-transparent, flexible halide perovskite solar cells with tunable color and transparency.

Researchers in Spain developed a new model incorporating dynamic shading conditions in Madrid to evaluate the yield and test control algorithms for vehicle-integrated PV (VIPV) systems.

A Chinese-Swedish research team has boosted the performance of tin-lead perovskite solar cells by modifying additives and post-treatment processes. The device also demonstrated improved stability, retaining 60% of its initial efficiency after 550 hours at 85 °C under maximum power point conditions.

Researchers from KAUST, TU Delft, and LMU Munich have improved the performance of monolithic perovskite-silicon tandem solar cells by modifying the physical structure at the front of the bottom heterojunction solar cell.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85  C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.
