Trinasolar Sets Fully Passivated Solar Module Efficiency world Record of 25.44%
Trina Solar, a leading name in photovoltaic (PV) technology, has achieved a remarkable milestone in solar energy efficiency. The company announced that its high-efficiency n-type solar total passivation (TOPAS) heterojunction (HJT) PV modules have achieved an aperture module efficiency of 25.44%, setting a world record for large-area HJT PV modules. This achievement was independently verified by the Fraunhofer ISE (CalLab) in Freiburg, Germany, solidifying its credibility.
Key Highlights of the Record-Breaking Module:
- Technological Foundations:
- Based on n-type TOPAS HJT solar cells, the module boasts exceptional performance advantages.
- Utilizes a large-area n-type phosphorus-doped Czochralski silicon (Cz-Si) wafer measuring 210×105 mm².
- Integrates advanced thin-film passivation, fully passivated contacts, and a progressive variable-frequency-RF p-type emitter.
- Design Innovations:
- Employs light-trapping technology to maximize photon absorption.
- Features ultra-high-density packaging for enhanced space utilization.
- Incorporates ultra-low-resistance interconnection to boost electrical performance.
- Historical Context:
- The module efficiency sets a record for crystalline silicon solar cells with front and back contact structures, reaffirming silicon’s dominance in PV technology.
- Builds on Trina Solar’s track record of efficiency breakthroughs:
- October 2024: 25.9% efficiency for n-type Cz-Si TOPCon solar cells.
- November 2024: 26.58% efficiency for the same technology.
- December 2024: 27.08% efficiency for n-type Cz-Si HJT solar cells.
