Open-access online tool helps homeowners replace gas boilers with PV-driven heat pumps
Italian research agency Enea has created a web tool that assesses the feasibility of replacing residential gas boilers with heat pumps by providing an estimate of the potential energy and economic savings. The app also provides information on the technical specifications of the photovoltaic system necessary to meet the heat pump’s electricity demand.
Austria deploys 1 GW of PV in January-September period
Austria added 1,036 MW of new solar capacity between January and September 2025, down from 1,419 MW over the same period in 2024, as political uncertainty, delayed legislation, and weakening residential demand strain the solar sector.
N-type wafer prices extend four-week slide amid weak demand, rising inventory concerns
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Huasun unveils 770 W, 2,000 V heterojunction solar module
The Chinese manufacturer said the higher-voltage design of the new module reduces cable, combiner, pile-foundation, and land-use requirements, delivering balance-of-system savings of up to CNY 0.15 ($0.012)/W in western China. The module offers a power output of 730 W to 770 W and a conversion efficiency of up to 24.8%.
Highly transparent perovskite solar cell achieves 18.22% efficiency
A research team in India has investigated the use of highly conductive transparent electrodes based on amorphous indium zinc made with a room temperature process in perovskite solar cells. The devices could be used in tandem and building-integrated PV applications.
Sungrow unveils new modular C&I battery with long-duration storage capability
The new 12.5 kWh pack-based design supports flexible configuration up to 250 kWh per system. An optional long-duration combiner box supports 2–4 clusters, expandable to 1,000 kWh and 8 hours of storage.
JinkoSolar achieves world record efficiency of 27.79% for TOPCon solar cell
The Chinese manufacturer says Germany’s Institute for Solar Energy Research Hamelin (ISFH) has independently verified the result.
New research sheds light on passivation-related defects in heterojunction solar cells
Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how hydrogenated amorphous silicon passivation help mitigate these defects and improve cell performance.
Spanish researchers developing rear-side concentrated PV modules for agrivoltaics
Researchers at University of Jaén in Spain have demonstrated a semi-transparent crystalline silicon solar photovoltaic module with rear-side optical concentrators for agrivoltaics applications.
Plenitude tests perovskite-silicon tandem solar modules in utility-scale installation pilot
The Italian renewable energy company said it will validate Swift Solar’s 28% efficiency perovskite-silicon tandem technology in a utility-scale project.
