Fortune highlights 28.00% THBC efficiency and 41 records
Trina Solar returned to Fortune’s 2026 Technology 50 list after Fortune released the ranking on June 25.
Fortune highlighted Trina Solar as the first photovoltaic and energy storage company on the STAR Market to cover four business segments: PV products, energy storage, integrated systems and digital energy services.
The company has set 41 world records in technological innovation across solar and storage.
Trina Solar’s next-generation THBC, or TOPCon-compatible Hybrid Back-contact Cell, reached 28.00% peak efficiency.
That result broke the 28.0% efficiency barrier for the first time on a 210R large-area cell.
Meanwhile, Trina Solar is advancing large-scale commercialization of TOPCon 3.0 technology.
The company pairs TOPCon 3.0 with THBC in a Dual-Engine Model designed to support more than 85% of global bifacial utility-scale photovoltaic applications.
For monofacial applications, THBC is moving into rapid industrialization because its higher front-side power output can deliver more value to customers.
In energy storage, Trina Solar has built full-stack self-development and manufacturing capabilities for battery cells, battery cabinets and complete energy storage systems.
The company also achieved conversion efficiency above 35% for small-area perovskite and crystalline silicon tandem cells.
Its large-area 210mm perovskite and crystalline silicon tandem solar cell reached 32.6% efficiency.
At module level, Trina Solar’s tandem photovoltaic module output has surpassed 907W.
The company also secured the first commercial order for high-efficiency perovskite and crystalline silicon tandem PV modules from a premium distributed energy customer worldwide.
Following that order, China’s tandem PV technology entered the global high-end residential market for the first time.
Qinghai zero-carbon computing project
Trina Solar is also advancing Electricity-Computing Synergy through integrated solar and storage systems and grid-forming energy storage technology.
The strategy links green electricity generation with AI-powered green computing.
Its business model covers direct renewable energy supply, multi-level energy storage, power-computing synergy, computing infrastructure and computing operations.
As part of that push, Trina Solar launched an AIDC Integrated Solution.
The company also deployed the world’s first high-altitude, zero-carbon computing-power demonstration project in Qinghai, China, with partners.
In Romania, Trina Solar developed an energy storage project that created a benchmark case.
