Risen claims 30.99% efficiency for perovskite-silicon tandem solar cell
The result was confirmed by China’s National Solar Photovoltaic Product Quality Supervision and Inspection Center. The tandem device is relying on a bottom cell based on a heterojunction design.
Tongwei drops plan to acquire Runergy
Chinese PV company Tongwei originally intended to invest CNY 5 billion ($1.8 billion) to buy a 51% stake in Runergy.
Study shows reducing number of solar modules per string reduces hotspots risk
Scientists in Indonesia have investigated early operational defects in a 24.9 MW solar PV system in Sumatra and have identified hotspot formation as the dominant defect. They also detected 282 cases of glass cracking, 350 cases of junction box failures and shading effects linked to module defects.
Boral trials recycled solar panels as sand alternative in concrete mix
Construction materials company Boral is trialling the use of crushed glass sourced from end-of-life and damaged solar panels as a partial replacement for natural sand in concrete production.
Tesla eyes Australia as Shanghai Megapack factory begins production
Tesla’s first battery energy storage manufacturing plant outside of the United States has started operating as global competition from Chinese firms and pricing pressures mount.
Back contact solar module manufacturing capacity may reach 1 TW by 2030, says tech expert
Radovan Kopecek, an expert on back-contacted (BC) solar cell and module technologies, spoke with pv magazine about BC manufacturing costs, efficiency and technical challenges. He believes that global BC solar module manufacturing capacity could reach 1 TW by 2030, potentially making BC products the industry’s mainstream technology. Kopecek added that 2028 will be a crucial year for its development, as most of the critical patents associated with this module tech will expire.
