Back-Contact Design
Both positive and negative electrodes are placed on the back of the cell, eliminating front-side shading and increasing light absorption for improved energy generation.

High Conversion Efficiency
Advanced passivation technology and optimized current pathways enhance power conversion efficiency compared to traditional solar cells.

  • Enhanced Aesthetics
    The absence of front-side grid lines not only improves efficiency but also creates a cleaner and more visually appealing design, making it ideal for architectural integration.

Versatile Applications
Suitable for residential rooftops, commercial solar systems, and large-scale solar farms, offering a high-efficiency and stable renewable energy solution.

About HPBC
HPBC Solar Cells:  Back-Contact Design

Recently, HPBC solar cells have captured industry attention thanks to their innovative back-contact design. HPBC—short for Hybrid Passivated Back Contact technology—repositions both the positive and negative electrodes to the rear of the cell, eliminating front-side shading and maximizing light absorption. This breakthrough design enables standard HPBC cells to achieve conversion efficiencies exceeding 25%, with PRO versions using hydrogen passivation reaching even higher levels.

In addition to superior performance, the improved aesthetic of HPBC cells makes them ideal for various applications, from distributed rooftop systems to large-scale commercial installations. Industry experts anticipate that as the technology matures and production scales up, HPBC solar cells will become a mainstream choice for next-generation high-efficiency photovoltaic systems, driving a greener global energy transition.
