Perovskite manufacturer SolaEon Technology has announced that its independently developed single-junction perovskite PV module has achieved a record-breaking efficiency of 25.27% on a 0.72 m2 sample area in stabilized testing, with reverse-scan efficiency reaching 25.47%. The company claims this is the world’s first perovskite module to surpass the 25% threshold, and the 19th time that it has set a record for perovskite cell/module efficiency.
Earlier this year, SolaEon revealed that modules from its 200 MW pilot line successfully passed TÜV Rheinland’s full IEC 63163 testing and obtained RoHS compliance certification. In April, its perovskite solar cell module achieved a steady state efficiency of 19.2% based on 1,027.1 cm2 area (see SolaEon Technology Announces World Record For Perovskite Modules). In June, it reported achieving 21.88% photoelectric conversion efficiency on a 0.64 m2 illuminated area, corresponding to a power of up to 140 W (see China Solar PV News Snippets).
Ningxia Hui Autonomous Region has released its Implementation Plan for Deepening Market-Based Reform of Renewable Power Tariffs. To be implemented effective October 1, 2025, the plan mandates full market participation for wind and solar power, with prices determined through trading. Distributed projects are encouraged to aggregate for market entry. In the spot market, bid caps are set at RMB 0.8/kWh ($0.11/kWh) and floors at RMB 0.04/kWh ($0.006/kWh), subject to adjustment. A settlement mechanism will balance deviations between market averages and the benchmark mechanism tariff, with the difference shared across industrial and commercial users.
The plan differentiates projects before and after June 1, 2025. Existing projects will apply fixed benchmark coal-fired tariffs (RMB 0.2595/kWh, $0.036/kWh), while new projects will determine tariffs via competitive bidding, capped at RMB 0.2595/kWh ($0.036)/kWh and floored at RMB 0.18/kWh ($0.025/kWh). The mechanism applies for 12 years.
Earlier this week, Heilongjiang Province released market-based pricing mechanism for renewables (see China Solar PV News Snippets).
Leading vertically integrated solar manufacturer LONGi has signed a memorandum of understanding (MoU) with Heriot-Watt University to expand cooperation in renewable energy education, research, and talent development. LONGi recognized Heriot-Watt as its ‘Outstanding Shared Partner in Sustainable Energy Education’ at the ceremony.
Since 2023, the partnership has implemented a rooftop solar project at Heriot-Watt’s Dubai campus, co-developed solar curricula, and co-hosted a PV power plant graduation design competition. LONGi has also worked with the university to establish the Middle East’s first Hi-MO X6 experimental power station and PV laboratory, offering students practical training opportunities.
Construction has officially begun on the Tibet-Southeast to Greater Bay Area ±800 kV UHVDC project, described as the most powerful and advanced flexible DC transmission system globally. The 2,681 km line crosses Tibet, Yunnan, Guangxi, and Guangdong provinces, with a transmission capacity of 10 GW. Commissioning is planned for 2029.
The project involves a total investment of RMB 53.2 billion ($7.42 billion) and is jointly developed by State Grid and China Southern Power Grid. It will draw on integrated hydro, wind, and solar resources from Tibet’s Yuqu and Zayü river basins, consolidating over 20 GW of clean energy. The line will deliver power directly to Guangzhou and Shenzhen load centers. Once operational, it will supply more than 43 billion kWh of clean electricity annually, fully from renewable sources, displacing 12 million tons of standard coal and reducing CO2 emissions by 33 million tons per year.
