Solar cell and module maker DAS Solar has announced that its self-developed TOPCon-Back Contact (TBC) module (referred to as DBC by the company) has achieved an output of 664.9 W and a full-area conversion efficiency of 24.61%. The module underwent third-party testing by the China Photovoltaic Testing Center (CPVT). This follows the company’s earlier milestone in September, when its DBC cell reached a certified efficiency of 27.77% (see China Solar PV News Snippets).
DAS Solar states that the TBC module, which the company refers to as the Diamond series, leverages its DBC technology in conjunction with TOPCon 5.0 tunnel-layer technology and a fully passivated selective-contact process, enabling a full-area efficiency of 24.61% on a standard format measuring 2,382 × 1,134 mm. The company expects that further optical and electrical optimization at the module level, combined with high-density encapsulation, could lift module power output above 680 W.
Shaanxi Lighte Optoelectronics Material Co., Ltd. (LTOM), a manufacturer of OLED organic materials, has announced its plans to enter the perovskite solar cell research and development (R&D) and manufacturing field. The company intends to raise up to RMB 766 million through the issuance of convertible bonds.
Of this amount, RMB 500 million will be invested in constructing new production workshops in Weinan, Shaanxi Province, supporting the development and manufacturing of OLED intermediates, OLED pre-sublimation materials, pharmaceutical intermediates, and perovskite materials.
An additional RMB 32 million will fund the establishment of a perovskite material R&D and device-validation innovation platform. Leveraging existing buildings, the platform will simulate real-world operating conditions, quantify degradation behavior, and identify root causes of instability in perovskite solar cells, providing key data for material modification and process optimization.
China’s National Energy Administration (NEA) has released the 2024 Monitoring and Evaluation Results on Renewable Energy Power Development. This report summarizes the performance against the provincial renewable energy consumption targets set in August 2024 by the NEA and the National Development and Reform Commission (NDRC).
For 2024, the NEA set renewable-energy consumption responsibility weights ranging from 21.8% to 70% across regions. The national average completion rate reached 35.2%, up 3.2 percentage points year-over-year (YoY). A total of 26 provinces (including autonomous regions and municipalities) met their targets, 3 failed, while 2 provinces were not part of the evaluation system.
China added 288 GW (AC) of new solar PV installations in 2024, a record high, followed by a decline in solar utilization. The national solar power utilization rate stood at 96.8% for 2024, down 1.1 percentage points YoY. Fujian, Zhejiang, Shanghai, and Chongqing achieved 100% utilization, while regions with comparatively low utilization included Tibet (68.6%), Qinghai (90.3%), Gansu (91.3%), Xinjiang (92.2%), Western Inner Mongolia (93.7%), and Shaanxi (94.5%).
Recently, China's New Energy Consumption Monitoring and Early Warning Center reported a 1.4 percentage point decline in China’s September solar power utilization rate (see China Solar PV News Snippets).
Chinese new energy developer CGN New Energy has issued a framework tender for its 2026 solar inverter procurement plan. The estimated procurement volume totals 8.5 GW, including 8 GW of string inverters rated 300 kW and above, and 50 MW of string inverters rated 150 kW and below.
The procurement will cover all PV projects implemented by the company between January 1 and December 31, 2026. The company has set a deadline of December 5, 2025, for bid submissions.
In August, the China General Nuclear Power Group subsidiary announced raising RMB 11.8 billion in equity funding to develop wind, solar, and energy storage projects in Inner Mongolia (see China Solar PV News Snippets).
