TNO, Solarge unveil lightweight perovskite solar module prototype
TNO and Solarge have developed a lightweight perovskite solar module prototype measuring 32 cm x 34 cm by combining roll-to-roll processing and low-weight panel materials. The Netherlands-based partners aim to scale the technology for broader commercial applications.
Improving solar cell performance with melanin, porous silicon powder
Researchers in Mexico have enhanced optoelectronic and solar cell performance by combining melanin with porous silicon powder. The compound improved photocurrent generation by boosting the luminescence of the silicon material.
China polysilicon prices fall 11.76% since early April peak
In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports thatglobal polysilicon negotiations remain challenging, as buyers and sellers continue to struggle to reach agreements on pricing amid a persistent supply-demand imbalance. Furthermore, it reveals that China’s polysilicon futures market could imply a further 13% drop for Nov 2025 delivery contracts.
Taiwan’s United Renewable Energy to lay off more than 100 employees
Taiwan’s United Renewable Energy (URE) says it plans to lay off more than 100 employees as it retires passivated emitter and rear contact (PERC) solar cell production lines in Taiwan to focus on its tunnel oxide passivated contact (TOPCon) module series.
Ascent Solar unveils production scale 15.7% CIGS modules for space
US-based Ascent Solar Technologies says its latest 30cm2 Titan solar module has a power density of 1,960 W/kg and is designed for space applications.
RENA Technologies warns of patent infringement in US, Indian markets
RENA Technologies GmbH says it plans to take legal action against unauthorized use of its water cap patent in the United States and India, amid evidence of infringement by unspecified Chinese suppliers manufacturing equipment for solar cell production.
Solarium Green Energy to restart solar module production with new 1 GW plant
Solarium Green Energy will resume solar module manufacturing with a new 1 GW fully automated facility in India, scheduled to begin commercial operation in the fourth quarter of fiscal 2025-26.
China’s SNEC 2025 show highlights PV industry resilience, storage growth
Chinese solar manufacturers showed resilience at the 2025 SNEC PV Power Expo in Shanghai despite a deepening supply glut, as strong demand for energy storage and emerging technologies offset a steep drop in new PV module launches. Tunnel oxide passivated contact (TOPCon) stayed dominant, while back-contact, perovskite, and lithium iron phosphate (LFP) storage solutions gained traction.
Longi unveils 700 W back-contact PV panel with world record silicon solar cell
Chinese solar manufacturer Longi unveiled a new PV module with 25.9% efficiency at the 2025 SNEC trade show this week in Shanghai, produced using both low- and high-temperature passivation techniques.
Perovskite solar cell based on chalcogen-molecules achieves 25.37% efficiency
An international research team has used Lewis molecules to improve efficiency and stability of a perovskite solar cell built with a fully encapsulated trapping tactic aimed to reduce perovskite surface defects. The cell achieved a certified power conversion efficiency of 25.18% and a champion efficiency of 25.37%.
