Perovskite manufacturer Huarou PV reported a conversion efficiency of 27.98% for its self-developed single-junction perovskite solar cell, certified by the National PV Industry Measurement and Testing Center (NPVM). The test device has an area of 0.051 m² and was measured under standard illumination conditions.
According to shareholder Ouhai Sci-tech Group, the result represents the first time a perovskite solar cell has exceeded the laboratory efficiency of all single-junction crystalline silicon cells. For comparison, the previous record of 27.9% was achieved by LONGi in 2025 using its HTBC structure and verified by Germany’s Institute for Solar Energy Research Hamelin (ISFH), later included in the Solar Cell Efficiency Tables (Version 67).
On the tandem front, Maxwell recently reported that its perovskite-HJT tandem cell achieved a certified conversion efficiency of 32.5% (see China Solar PV News Snippets).
The Shanxi Provincial Development and Reform Commission has revised its time-of-use (TOU) electricity pricing policy for commercial and industrial (C&I) users, effective May 1, 2026. The updated mechanism introduces 4 seasonal tariff schedules and aims to improve renewable energy absorption through price signals.
The policy reclassifies certain daytime hours, when solar output is typically highest, from flat to valley or flat periods, encouraging higher electricity consumption during periods of surplus PV generation. It also introduces a ‘deep valley’ price period from 13:00 to 15:00 during the Spring Festival, Labor Day, and National Day holidays, set at 20% below the standard valley rate.
In addition, the regulation widens the tariff spread to encourage load flexibility and storage deployment. Peak prices can rise by up to 60%, valley prices may drop by 55%, and critical peak periods can reach an additional 20% above the peak tariff.
Quartz crucible manufacturer OJing Technology announced an adjustment to its procurement agreement with Sibelco North America for high-purity quartz sand. The contract, originally signed in 2024, had a planned purchase value of $350 million.
Due to ongoing cyclical adjustments in the PV industry and lower utilization rates across the supply chain, both parties agreed to revise the contract value downwards to $270 million. The agreement’s performance period has also been extended by 1 year.
Earlier this year, OJing announced its decision to halt production at its wholly-owned subsidiary Tianjin Ouchuan and partially suspend production lines at Yixing Ouqing (see China Solar PV News Snippets).
China released a summary of the draft 15th Five-Year Plan for National Economic and Social Development (2026-2030), outlining a strategy centered on intelligent, green, and integrated development. The plan highlights the role of advanced manufacturing in building a modern industrial system.
It calls for accelerated construction of new energy infrastructure and the ‘moderately advanced’ deployment of emerging infrastructure types. The strategy also emphasizes strengthening supply chain autonomy while advancing carbon peaking and neutrality goals through energy structure optimization and implementation of a dual-control system for both total carbon emissions and emission intensity.
China Huadian has released the bid evaluation results for its 8 GW centralized PV module procurement, divided into 2 sections.
Section 1 covers 6 GW of n-type high-efficiency modules with a minimum conversion efficiency requirement of 23.8%. Huadian has shortlisted 10 companies, including GCL SI, AIKO, and TCL Solar, as winning or backup candidates, with bid prices ranging from RMB 0.82/W to RMB 0.925/W and averaging RMB 0.8953/W.
Section 2 covers 2 GW of n-type standard modules with a minimum efficiency of 22.8%. Similar to Section 1, 10 companies, including GCL SI, JinkoSolar, and DAS Solar, were shortlisted, with prices ranging from RMB 0.77/W to RMB 0.893/W and averaging RMB 0.8527/W.
Recently, Huadian shortlisted AIKO and LONGi for its 800 MW PV module tender for projects in Gansu Province (see China Solar PV News Snippets).
