Leading PV solution provider Trinasolar has reported a conversion efficiency of 28.00% for its TOPCon-compatible hybrid back-contact (THBC) solar cell, verified by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
The company claims this achievement to be a first for a 210R large-format crystalline silicon cell. The THBC architecture combines TOPCon passivating contacts, HJT-level surface passivation, and a back-contact electrode design.
The company said the technology is compatible with mainstream TOPCon production lines and supports thin wafers in the 110-130 µm range. Trinasolar is advancing industrialization through its pilot line and expects module output based on standard formats to exceed 700 W. The first THBC-based products are expected to be launched soon.
Earlier this month, the Jinneng Qizi Bay tidal flat PV project in Qingdao, Shandong Province, with modules supplied by Trinasolar, conducted trial operations (see China Solar PV News Snippets).
Major Chinese energy developer China Huaneng has commissioned a hydropower-PV hybrid project in Yunnan province, featuring a fully domestically developed control system.
The project has a total installed capacity of 5.43 GW, including 4.2 GW of hydropower and more than 1.23 GW of solar PV. It integrates output from 16 PV sites with the company’s Xiaowan hydropower plant through coordinated dispatch, using hydropower flexibility to stabilize PV fluctuations.
The company said all core control systems and key PV station equipment, including monitoring, protection, and compensation systems, were 100% domestically produced.
Recently, China Huaneng announced the results of its construction and installation tender covering 2.18 GW of PV projects in Pu’er City, Yunnan Province (see China Solar PV News Snippets).
PV module and cell manufacturer EGING PV has signed a pre-restructuring investment agreement with Ningbo Ruilian and SolarSpace.
The investors will subscribe to at least 455 million new shares for a total of RMB 819 million, including RMB 719 million from Ningbo Ruilian and RMB 100 million from SolarSpace. Following completion, Ningbo Ruilian is expected to become the controlling shareholder.
Ningbo Ruilian is a subsidiary of DCL Investments, which focuses on distressed asset investment and management.
In February, EGING PV announced that its creditors had applied for corporate restructuring due to the company's failure to pay maturing debts and apparent lack of solvency (see China Solar PV News Snippets).
Sungrow New Energy has signed a strategic cooperation agreement with solid-state battery manufacturer Gemstone to advance sulfide-based all-solid-state battery applications. Sungrow New Energy is a subsidiary of leading PV inverter and energy storage system supplier Sungrow.
The partnership will focus on developing energy storage systems for utility-scale PV, residential, commercial & industrial applications, and EV charging infrastructure, integrating solid-state battery technology into broader energy solutions.
In a press conference to discuss the recently released data, China’s National Energy Administration (NEA) reported total new solar installations of 41.19 GW in Q1 2026, down 31% year on year. This is, however, slightly below the 41.39 GW figure it released last week (see China Adds 41.39 GW Solar PV In Q1 2026 As Growth Slows).
Distributed solar installations declined 40.6% to 21.57 GW, while centralized installations fell 16.2% to 19.62 GW. Despite the slowdown, cumulative solar capacity reached 1.241 TW by the end of March, up 31.2% year on year.
Renewable energy accounted for 70% of total new capacity additions in the quarter, reaching 58.93 GW. Solar power generation rose 18.5% to 275.9 TWh, with a utilization rate of 90.6%.
