As state-of-the-art single-junction silicon technologies approach their practical performance ceiling in production settings, the industry is increasingly exploring next-generation architectures to achieve further efficiency gains. Among these, tandem solar cells – particularly silicon-perovskite tandems – have emerged as the most promising pathway.
However, significant challenges remain before tandem technologies can reach large-scale commercialization. Issues related to stability, manufacturability, materials integration, and long-term reliability remain active areas of research and engineering development.
At the TaiyangNews Next-Generation PV Technology 2026 Virtual Conference, Bin Fan, Founder and Chairman of GCL Optoelectronic, will speak on how GCL is taking a simplified route to next-generation PV technologies.
The virtual conference is scheduled for tomorrow, April 22, 2026, from 09:30 to 13:00. Participation in the event is free and can be done here.
TrinaTracker, the tracker system subsidiary of Trinasolar, announced that its FixOrigin solution has received Environmental Product Declaration (EPD) certification for ground-mounted PV racking systems, verified by Bureau Veritas. The company said this represents the first EPD certification for such systems in the industry. FixOrigin has also obtained UL 2703 certification, completing a full set of international certifications and carbon footprint verifications across TrinaTracker’s product portfolio. The latest among its certifications was the Product Carbon Footprint (PCF) Certification for its Vanguard 2P tracker and PCF Reduction Verification for Vanguard 1P (see China Solar PV News Snippets).
Back contact (BC) cell and module manufacturer AIKO plans to invest RMB 1.665 billion to upgrade 11 GW of PV cell capacity to All Back Contact (ABC) technology across its 2 manufacturing bases.
The company will invest RMB 721 million to upgrade 5 GW at its Yiwu, Zhejiang, facility from PERC to ABC, with commissioning expected in Q3 2026. It plans to use a further RMB 944 million to upgrade 6 GW at its Chuzhou, Anhui, facility from TOPCon to ABC, with commissioning expected in Q4 2026.
AIKO said the upgrades will deploy its BC technology to produce ABC cells with higher conversion efficiency and improved performance.
AIKO was recently shortlisted by China Huadian for its 6 GW Section 1 of 8 GW module tender (see China Solar PV News Snippets).
Integrated PV manufacturer JA Solar has released official guidance pricing for its distributed PV modules, ranging from RMB 0.85 to RMB 0.93/W for its DeepBlue 4.0 and DeepBlue 5.0 series.
Specialized modules are priced separately, with anti-dust modules at RMB 0.89-0.94/W, fire-resistant modules at RMB 0.91-0.935/W, hail-resistant/high-load modules at RMB 0.89-0.915/W, and anti-glare modules at RMB 0.89-0.91/W.
Jilin Province has released its 15th Five-Year Plan (2026-2030), targeting 70 GW of combined wind and solar capacity by 2030.
The plan emphasizes expanding new energy consumption, particularly in western regions, while developing distributed wind and PV projects in central and eastern areas. It also supports new energy bases linked to power transmission projects from Jilin to Beijing.
To support integration, the province will deploy large-scale and diversified energy storage systems to enhance utilization, reliability, and grid support.
