GCL Optoelectronics Wins 1.2 MW Huaneng Tandem Solar Contract With 25% Efficiency Requirement
1 articles · Updated · Precedence Research · Jul 6
Summary
GCL Optoelectronics signed a 1.2 MW commercial tender from China’s Huaneng Power for perovskite-silicon tandem photovoltaic modules, marking a public utility-scale order for the emerging technology.
The contract requires IEC-certified modules with conversion efficiency above 25%, a 25-year performance guarantee and delivery before the end of 2026.
Huaneng’s order is described as the first publicly announced commercial perovskite tandem module project among China’s five largest state-owned power companies, signaling movement beyond lab and pilot stages.
China is a pivotal market for that shift: Asia-Pacific held 48% of the perovskite photovoltaics market in 2025, while China produces more than 80% of global solar modules.
The broader perovskite photovoltaics market was valued at $1.08 billion in 2025 and is forecast to reach $17.08 billion by 2035 as tandem designs push higher output at lower cost.
Beyond clean energy, could perovskite technology dismantle the current global monopoly on solar manufacturing?
Can perovskite prove its 25-year durability in time to challenge the dominance of ever-cheaper silicon panels?
As solar cells become flexible and transparent, are we ready for devices and buildings that power themselves?
GCL Optoelectronics Wins China’s First 1.2 MW Commercial Perovskite Tandem Solar Module Contract: A Milestone for Large-Scale Deployment and Durability Testing
Overview
In July 2026, GCL Optoelectronics secured a landmark contract to supply 1.2 MW of commercial perovskite/silicon tandem solar modules to the Huaneng Clean Energy Research Institute. This deal marks the first publicly tendered commercial procurement of perovskite technology among China’s major state-owned power groups, representing a pivotal commercialization milestone. It signals a major step forward for integrating advanced perovskite technology into large-scale energy projects. Huaneng’s previous investment in a 5 MW perovskite demonstration plant at Qinghai’s Gonghe park highlights its strategic interest and sets the stage for broader adoption of this innovative solar solution.
