IBC Technology Concept and Advantages

IBC (Interdigitated Back Contact) cells are the most representative type of back-contact solar cells. These cells move both the positive and negative electrode contacts to the back of the solar cell, making them compatible with various cell technologies such as HJT (Heterojunction), TOPCon (Tunnel Oxide Passivated Contact), and others. The front of the cell is free of grid lines, allowing it to absorb sunlight across the entire surface without shading. This makes IBC cells ideal for applications in solar panels, photovoltaic systems, solar cell modules, and other areas, with broad prospects for future development.

Advantages: IBC cells are the fourth generation of photovoltaic cell technology, following BSF (Back Surface Field), PERC (Passivated Emitter and Rear Cell), and HIT (Heterojunction with Intrinsic Thin-layer) cells. They offer high conversion efficiency, high energy density, and long service life, among other benefits.
