Pilot lines are running. Prototypes are being tested. But can tandem modules actually scale?
Chris Case, CTO at Oxford PV, will bring a commercialization lens to silicon-perovskite tandems in his presentation at the TaiyangNews Next-Generation PV Technology 2026 Virtual Conference.
Tandem solar cells, particularly silicon-perovskite tandems, have emerged as the most promising pathway forward. By combining complementary absorber materials, tandem structures allow a broader portion of the solar spectrum to be utilized, breaking the barriers of single-junction devices. Pilot lines are running, and early prototypes are being tested, but stability, manufacturability, and long-term reliability remain the critical challenges to scale.
With key voices from across the PV ecosystem, the event explores how the industry can address these challenges.
Scheduled for April 22, 2026, from 09:30 to 13:00, participation in the event is free and can be done here.
The State Grid Energy Research Institute has released its China Electricity Supply and Demand Analysis Report 2026, forecasting that wind and solar will account for 49.1% of China’s total installed power capacity by 2026, up 1.8 percentage points from 2025.
Total installed capacity is projected to reach 4.28 billion kW, with thermal power at 38.4%, hydropower at 10.8%, and nuclear at 1.7%. Electricity consumption is expected to reach 10.9 trillion kWh, up 5.5% year on year.
By 2030, total installed capacity is forecast to reach 5.4 billion kW, with new energy capacity exceeding 2.8 billion kW.
Battery and energy storage solution provider Shuangdeng Group plans to invest in a 12 GWh semi-solid battery project for artificial intelligence data center (AIDC) applications under an agreement with the Jiangsu Xuyi Economic Development Zone.
The project will produce semi-solid cells and integrated systems for AIDC use and forms part of the company’s ‘backup power + energy storage’ solution for computing infrastructure. The company stated that it expects this investment to strengthen its market position in the AIDC energy storage sector and support its long-term business expansion goals.
The Sichuan Provincial Government has issued its 15th Five-Year Plan (2026-2030), targeting more than 50 GW of new renewable energy capacity additions during the period.
The plan prioritizes the development of hydro-wind-solar integrated bases in the upper Jinsha River, Yalong River, and Daduhe River basins, alongside expansion in resource-rich regions. It also includes deploying new energy storage stations, supported by coal and gas generation, to maintain grid stability.
Earlier this year, Aba County in Sichuan Province completed the project filing procedures for a total of 1.85 GW of solar PV capacity (see China Solar PV News Snippets).
Zhejiang Province has released the results of its first 2026 mechanism tariff bidding for new energy projects, with a clearing price of RMB 0.3816/kWh.
A total of 31,024 PV projects were selected, representing 4.29 GWh of mechanism-generated electricity. The clearing price declined from RMB 0.3929/kWh in 2025.
Zhejiang was one of the provinces to record an over 97% PV utilization rate in Jan-Feb 2026 (see China Solar PV News Snippets).
PV inverter and energy storage manufacturer Deye reported 2025 revenue of RMB 12.22 billion, up 9.08% year-on-year (YoY), while adjusted net profit rose 8.2% to RMB 3.04 billion.
Energy storage inverter sales increased 42.72% to 771,500 units, and battery pack sales rose 67.16% to 777,000 units, while PV inverter shipments grew 3.76% to 862,200 units.
The company expects Q1 2026 adjusted net profit of RMB 1.04 billion to RMB 1.14 billion, representing a YoY growth of 69.78%-86.11%, and is preparing for an H-share listing in Hong Kong alongside investment in a new production base in Malaysia.
