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.
Switzerland introduces winter electricity bonus for solar installations
Switzerland is implementing a new winter electricity bonus for solar installations larger than 100 kW that generate over 500 kWh/kW of electricity in the winter half-year from October 1 to March 31. The country’s Federal Council has also raised the target for electricity generated by photovoltaics to 18.7 TWh by 2030.
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.
IRENA seeks consultant for solar feasibility study in Ukraine
The International Renewable Energy Agency (IRENA) is seeking a consultancy to conduct a feasibility study for a utility-scale solar plant in Ukraine, with applications due Dec. 23.
Philippines commissions 6.5 MW solar project for social housing
The 6.55 MW project, hailed as the world’s first grid-connected, solar rooftop project within a social housing community, equipped almost 2,000 houses with solar panels.
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.
