First attempt to build lead-free perovskite-CIGS tandem solar cells
Indian researchers simulated a novel pairing of a CsGeI3 lead-free halide perovskite top cell with a copper-indium-gallium-selenide bottom cell. The resulting tandem device has the potential to achieve a power conversion efficiency of 26.06%
Data center firms could buy utilities and add renewables, says trade group exec
Data center firms could purchase electric utilities and add renewable generation in the United States, says Simon Mahan, executive director of the Southern Renewable Energy Association, which represents the wind, solar, storage and transmission sectors.
Photovoltaics for cocoa pod splitting
Scientists have designed a cocoa pod splitting device that runs on five monocrystalline PV panels. They have simulated its operation and have found it can achieve a splitting efficiency of 98.92%.
How to store PV power with hybridization of lithium-ion batteries, supercapacitors
Researchers in Denmark have developed a new sizing strategy to combine PV system operation with lithium-ion batteries and supercapacitors. The proposed approach is claimed to reduce annual battery cycle by 13%.
Record-warm July boosts solar in North, dampens South and East
In a new weekly update for pv magazine, Solcast, a DNV company, reports that persistent high‑pressure over Scandinavia delivered significantly elevated irradiance up to 30 % above normalin July, while central and eastern Europe faced reduced solar generation under increased cloud cover and rainfall.
Dutch heating specialist offers residential heat pump for flat roofs
WeHeat said its monoblock air-to-water heat pump features a seasonal coefficient of performance of 4.7 and propane as the refrigerant. The system is available in four versions with output ranging from 8 kW to 11 kW.
The impact of soldering flux on TOPCon solar cell degradation
UNSW researchers have investigated the impact of two types of soldering fluxes on TOPCon solar modules under damp heat conditions and have found that “no-clean” soldering fluxes can cause severe corrosion of front silver-aluminum contacts. The researchers have also found that denser metallisation structures and lower aluminium content improve corrosion resistance.
FTC Solar introduces solar tracker for high wind regions
The 1P single-axis tacker is engineered to withstand winds up to 150 mph.
US transformer supply may fall sharply in 2025, says Wood Mackenzie
Wood Mackenzie says US power transformer supply could fall 30% and distribution transformers 10% in 2025 due to surging demand and limited manufacturing capacity.
PVFarm enhances tracker, terrain tools for large-scale PV planning
The U.S. software company has improved its single-axis tracker and fixed tilt configurators for planning large-scale projects, adding customization features and additional support for terrain-conforming designs.
