Heterojunction modules refer to a type of solar cell technology that combines different semiconductor materials to improve efficiency. These modules typically utilize a heterojunction of crystalline silicon and thin-film materials like amorphous silicon. The combination allows for better light absorption and reduced recombination losses, which can significantly enhance the overall performance of the solar cells.
Key Features of Heterojunction Modules:
High Efficiency: HJT modules often achieve higher efficiencies compared to traditional silicon solar cells due to the use of multiple layers.
Temperature Coefficient: They usually have a better temperature coefficient, meaning they perform better in higher temperatures.
Bifacial Capability: Many HJT modules are bifacial, allowing them to capture sunlight from both sides, increasing energy yield.
Thin and Lightweight: These modules can be thinner and lighter than traditional options, making them easier to install.
Durability: HJT modules often show improved resistance to degradation over time.
Applications:
Heterojunction modules are suitable for various applications, including residential, commercial, and utility-scale solar power systems. Their efficiency and durability make them a popular choice in areas with limited space or where maximizing energy production is crucial.
