PERCPassivated Emitter Rear Cell:

   - Cost-effectiveness: The PERC technology boasts mature manufacturing processes, akin to traditional solar cell production, resulting in lower manufacturing costs. This positions PERC as a cost-effective choice, particularly for large-scale solar projects.

   - Stability in Performance: Widely applied in commercial settings, PERC technology demonstrates stable performance, making it suitable for projects requiring long-term reliability.

   - Widespread Application: With its cost-effectiveness and stable performance, PERC technology has found extensive applications in both commercial and industrial sectors, making it especially suitable for large-scale solar ventures.


TOPConTunnel Oxide Passivated Contact:

   - High Conversion Efficiency: TOPCon cells consistently achieve high conversion efficiencies, making them ideal for projects with stringent requirements for energy output.

   - Low-Temperature Manufacturing: The manufacturing process involves lower temperatures, contributing to energy savings and environmental friendliness, making it suitable for environmentally conscious projects.

   - High-Temperature Stability: TOPCon cells exhibit stability in high-temperature environments, making them advantageous in regions with hot climates.

   - Extended Lifespan: TOPCon cells generally boast an extended lifespan, often surpassing 25 years.


HJTHetero junction Technology:

   - High Conversion Efficiency and Low Light Degradation: HJT technology typically achieves high conversion efficiency, excelling particularly in low-light conditions.

   - Adaptability to Temperature Changes: HJT cells remain stable in high-temperature environments, making them suitable for regions with challenging climates.

   - Suitability for Space-Limited Projects: Due to their high conversion efficiency and relatively small size, HJT cells are well-suited for space-limited projects such as rooftop installations.

  - Extended Lifespan: HJT cells commonly have an extended lifespan, often exceeding 30 years, ensuring sustained high conversion efficiency.
