Vitor Rodrigues, Technical Director, EU & LATAM at GCL System Integration, will be speaking on the topic GCL’s Modules with Built-in Traceability and Carbon Data at the TaiyangNews Virtual Conference on PV System Technology Trends – SNEC & Intersolar Product Review.
The Conference will be held on 2 separate days – June 24 & June 26, from 09:30 to 13:00 – and will explore important technology highlights and trends from both SNEC and Intersolar Europe 2025. The key takeaway of this event will be insights from market and innovation leaders about the latest breakthroughs shaping the future of photovoltaics.

Solar PV leader LONGi has announced it has achieved 2 significant breakthroughs in tandem solar cell and BC module efficiency. The company’s proprietary large-area silicon–perovskite 2-terminal tandem solar cell reached a certified conversion efficiency of 33% on a 260.9 cm2 device, as verified by the US National Renewable Energy Laboratory (NREL). This sets a new global record for large-area tandem cells. Additionally, the company’s back-contact (BC) module, based on its proprietary BC cell technology, breached the 26% module efficiency threshold. Both achievements have been included in Dr. Martin Green’s 66th edition of the Solar Cell Efficiency Tables.
LONGi, along with multiple institutions, jointly launched the Initiative to Improve the Quality and Testing Standards of the Photovoltaic Industry’s Full Life Cycle at SNEC 2025 (see China Solar PV News Snippets).
Vertically integrated solar manufacturer JA Solar has announced that its n-type TOPCon DeepBlue module has reached a conversion efficiency of 25.5% with a front-side power output exceeding 700 W, as certified by TÜV. This is a new record for n-type TOPCon module efficiency. The module uses JA Solar’s Bycium+ 5.0 cell developed in-house, featuring low-boron doping on the front, local poly technology on the rear, and advanced printing techniques. The cell achieved an open-circuit voltage of 749.0 mV, which JA Solar claims to be the highest among commercial TOPCon cells to date.
JA Solar recently announced being named among the shortlisted candidates for the CNNC 2025-2026 Photovoltaic Module Equipment Level 1 Centralized Procurement Project (see China Solar PV News Snippets).
Integrated solar manufacturer Tongwei Group and China Huaneng are jointly developing what they call China’s first ‘solar-grazing complementarity’ pilot project on degraded grasslands in Damao Banner, Inner Mongolia. With a planned capacity of 50 MW, the project is scheduled to reach grid connection by the end of September 2025. Once operational, it is expected to generate about 85 million kWh of clean electricity annually, offsetting 90,000 tons of CO2 emissions each year.
The project integrates the ecological characteristics of the local grassland to address technical challenges such as high-frame design and enhanced wind load resistance. It aims to enable multi-functional land use by combining PV power generation with grassland restoration and livestock farming, offering a sustainable development model for degraded grasslands.
Renowned heterojunction (HJT) manufacturer Huasun Energy and TÜV Rheinland have jointly launched the first evaluation framework for vertically mounted solar PV modules. According to the duo, this framework addresses a key bottleneck in the application of vertical solar installations. The new solution aims to establish standardized methods for assessing power generation performance, reliability, and economic value throughout the vertical module lifecycle, from lab testing to real-world deployment. Huasun highlights that the absence of unified standards has hindered wider adoption, and this collaborative initiative will fill that gap with a holistic evaluation system.
Huasun Energy showcased its high-bifacial vertical PV modules at the recent Intersolar Europe 2025 (see Vertical PV And Pre-commercial Tandem Modules From Huasun). Christian Comes, Huasun's Director of Business Development, spoke to TaiyangNews about vertical PV's advantages in some detail at the event (see Huasun’s Christian Comes speaks to TaiyangNews at Intersolar Europe 2025).
GoodWe, JA Solar, and Tongwei are among 13 Chinese companies that have launched the Supply Chain ESG Stewardship Initiative (SCSI). This multi-industry alliance aims to build a science-based and inclusive ESG assessment framework for supply chains, streamlining audit procedures by mitigating discrepancies in ESG standards. The initiative also seeks to integrate ESG performance into financial product innovation, enabling companies to embed deeply into global value chains and contribute more effectively to global sustainability goals. Other participants include leading firms from the automotive and tech sectors, such as XPeng and NIO.
