PV cell and module manufacturer Runergy has announced that its independently developed TOPCon 3.0 large-area module achieved a conversion efficiency of 25.9% in testing and certification at the US National Laboratory of the Rockies (NLR). The company said the result sets a new efficiency record for crystalline-silicon modules, excluding HBC modules.
According to Runergy, the module was fabricated using processes on a pilot line with mass-production capability, while the mass-production version in a standard module format can reach 660-670 W. The module uses a multi-cut-cell circuit design and edge-passivation technology, together with high-transmittance encapsulation materials and low-resistance ribbons, to reduce electrical and optical losses.
Runergy introduced its next-generation TOPCon cell with a certified conversion efficiency of 26.9% at Intersolar Europe 2026 (see Runergy Introduces TOPCon Cell With 26.9% Conversion Efficiency).
Perovskite tandem-cell developer Becquerel has signed a strategic cooperation agreement with AI for Science solutions provider Ximu Technology to jointly develop high-efficiency, highly stable perovskite materials. The partners will combine AI for Science (AI4S) with perovskite PV technology and explore broader applications of AI for Materials in additional fields.
Under the agreement, Ximu Technology will apply AI models, physics-based modeling and data-computing capabilities, combined with Becquerel’s expertise in perovskite-crystalline silicon tandem cells, to accelerate material screening and device-performance optimization. Planned cooperation areas include intelligent recommendations for new perovskite materials and high-throughput experimentation.
PV and aerospace optoelectronic testing equipment provider Delicacy Laser has launched an AAA-rated AM0 steady-state solar simulator, primarily designed for I-V testing of space-grade gallium arsenide (GaAs) solar cells and irradiation-aging tests of space optoelectronic materials. The simulator achieves 100% spectral coverage (SPC 100%) across the 300-1,800 nm range, while its spectral match, irradiance non-uniformity, and temporal instability all meet Class A requirements.
Its light source has an effective service life of more than 20,000 hours, about 20 times the roughly 1,000-hour life of conventional xenon-lamp systems. The company said the design addresses the short service life of high-precision steady-state light sources and gaps in the wavelength coverage of LED-based systems, while reducing maintenance and calibration frequency over the equipment’s lifecycle.
Delicacy Laser recently delivered its self-developed transient IV testing system for triple-junction GaAs concentrator cells to a domestic commercial aerospace R&D company (see China Solar PV News Snippets).
China Energy Engineering Corporation (Energy China, or CEEC) has announced the winning bidders for its 2026 centralized procurement of PV mounting structures. The procurement is estimated to cover 1 million tons of fixed-tilt structures and 4 GW of trackers across 7 lots.
A total of 45 companies were selected as winning bidders, including Jiangsu Guoqiang Xingsheng, TBEA, and Trinasolar. Although the announcement disclosed the total bid amounts submitted by individual winners, it did not specify the procurement volume for each lot.
China Energy recently announced the results of its 2026 centralized procurement of 30 GWh of LFP ESS and battery cells (see China Solar PV News Snippets).
Silicon materials manufacturer Hoshine Silicon reported revenue of RMB 10.16 billion for the first half of 2026, up 3.94% year on year. The company recorded a net profit of RMB 324.5 million, but an adjusted net loss of RMB 30.2 million, although the loss narrowed from a year earlier. Last month, Hoshine forecast its H1 2026 net profit to range between RMB 320 million and RMB 380 million, and its adjusted net loss between RMB 28 million and RMB 33 million (see China Solar PV News Snippets).
Hoshine attributed the improvement mainly to a higher utilization rate at its industrial silicon operations, which drove significant growth in production and sales volumes. An improved supply-demand balance and higher product prices in the silicone industry also supported its year-on-year earnings recovery.
During the reporting period, Hoshine Silicon’s two polysilicon subsidiaries generated combined revenue of RMB 329.19 million and reported a combined net loss of RMB 1.063 billion.
As of June 30, 2026, Hoshine Silicon had annual production capacity of 1.22 million tons of industrial silicon, 1.73 million tons of silicone monomers, and 50,000 tons of polysilicon.
