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.
German developer commissions nation’s largest solar carport
Germany has brought a 17 MW photovoltaic carport online in Riedstadt, Hesse, spanning 76,000 square meters. It is expected to generate about 17 GWh per year, according to project developer Nawasol.
European solar manufacturing ‘considerably behind’ NZIA targets, says EU observatory
A report from the Clean Energy Technology Observatory finds that while the EU is a technology leader in PV inverters, trackers and mounting structures, its manufacturing capacity in solar ingots, wafers, cells and modules falls far behind targets set by the Net Zero Industry Act.
Nexwafe secures cash injection from EU scale up funding
German solar wafer manufacturer Nexwafe is one of eight companies receiving investment in the latest round of the European Commission’s Strategic Technologies for Europe Platform (STEP) Scale Up call, an initiative addressing a market gap in deep tech funding in Europe.
ChasingLight Technology launches indoor organic PV modules
The China-based organic photovoltaics manufacturer has launched a line of indoor PV modules suitable for integration into digital office products and electronic devices.
Photonic curing could accelerate transition to copper-metallized solar cells
Researchers in the United States have developed a photonic curing technique using laser sintering to rapidly heat and cure copper pastes on temperature-sensitive solar cell substrates without causing thermal stress. The process purportedly produces dense, low-porosity copper layers with strong adhesion to indium tin oxide, achieving low bulk and contact resistivity.
