All solar cell efficiencies at a glance – updated
The research group led by Professor Martin Green has published Version 66 of the solar cell efficiency tables. There are 17 new results reported in the new version.
Longi launches residential heterojunction back-contact solar module with 25% efficiency
Longi has developed the Hi-MO S10, a residential heterojunction (HJT) back-contact solar module with 25% efficiency, combining 27.6%-efficient cells with up to 510 W output and 252.3 W/m² power density.
Solar technologies at crossroads
Experts set to speak at the NetZero Milan Expo-Summit 2025 on May 15 have told pv magazine that tunnel oxide passivated contact (TOPCon) will remain the dominant cell technology in the near term due to ongoing advancements, despite rising competition from back-contact and heterojunction technologies.
Longi expresses interest in solar manufacturing in Algeria
A delegation from Chinese module maker Longi met with officials from Algeria’s Ministry of Energy and Mining last week to discuss cooperation that would support Algeria’s domestic solar market, including a solar manufacturing facility.
Longi achieves 34.85% efficiency for two-terminal tandem perovskite solar cell
The result was confirmed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
Longi claims world’s highest efficiency for silicon solar cells
Longi said it has achieved a 27.81% efficiency rating for a hybrid interdigitated back contact, as confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
Longi unveils anti-dust back contact solar module with 24.8% efficiency
Longi has released a back-contact solar module with 24.8% efficiency, featuring a power output of up to 670 W and a temperature coefficient of -0.26% per degree Celsius.
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.
JinkoSolar sues Longi for TOPCon patent infringement
JinkoSolar has filed a patent infringement lawsuit against Longi over tunnel oxide passivated contact (TOPCon) solar cell technology, with the first hearing scheduled for Feb. 13, 2025.
