WINHITECH
Zhejiang Winhitech New Energy Co., Ltd. (WINHITECH) is at the forefront of heterojunction (HJT) solar technology, emphasizing high-efficiency photovoltaic solutions.
Their commitment to innovation and quality positions them as a significant player in the renewable energy sector.
Advantages of HJT
High Conversion Efficiency: HJT cells achieve conversion efficiencies up to 26%, surpassing traditional solar technologies.
Superior Bifacial Performance: With bifaciality rates exceeding 90%, HJT modules can capture sunlight from both sides, increasing energy yield.
Low Temperature Coefficient: A temperature coefficient of -0.24%/°C ensures consistent performance even in high-temperature environments.
Enhanced Durability: HJT modules exhibit minimal degradation, with less than 1% in the first year and an annual rate of ≤0.3% thereafter, ensuring long-term reliability.
Aesthetic Appeal: The uniform appearance of HJT modules makes them suitable for applications where visual integration is essential.
Cell Manufacturing Process
WINHITECH’s HJT cell production involves several key steps:
Surface Preparation: Cleaning and texturing the silicon wafer to enhance light absorption.
Amorphous Silicon Deposition: Applying intrinsic and doped amorphous silicon layers to form the heterojunction.
Transparent Conductive Oxide (TCO) Application: Adding TCO layers to facilitate efficient charge collection.
Metallization: Implementing fine-line metallization techniques to minimize shading and resistive losses.
Encapsulation: Sealing the cells within protective materials to ensure durability and longevity.
WINHITECH's Comprehensive Strength
Production Capacity: WINHITECH has established a robust manufacturing base in Zhoushan, Zhejiang Province, with an initial capacity of 3 GW for HJT cells and 5 GW for modules. Plans are underway to expand this to 30 GW for cells and 15 GW for modules.
Global Collaborations: The company has partnered with leading Japanese manufacturers to supply high-efficiency HJT products, marking a significant step in its international expansion.
Industry Recognition: WINHITECH’s advancements in HJT technology have earned it a place among the “Top 100 Photovoltaic Companies,” reflecting its commitment to innovation and quality.
Research and Development: Continuous investment in R&D enables WINHITECH to refine its technologies, such as the development of 0BB (zero busbar) HJT cells, which reduce material usage and enhance performance.
