? What is TopCon Technology
Tunnel Oxide Passivated Contact (TOPCon) represents a significant advancement in solar cell technology. It's a high-efficiency solar cell architecture that combines the benefits of conventional cells with passivated contacts to achieve superior performance.
TopCon cells feature a thin tunnel oxide layer and a polysilicon layer on the rear side of the cell, creating a sophisticated passivated contact structure that minimizes recombination losses and maximizes efficiency.
Key Features: Bifacial design, lower temperature coefficients, higher efficiency, and excellent reliability compared to traditional PERC cells.
Why Choose TopCon Technology?
Higher Efficiency
TopCon cells achieve conversion efficiencies of 23-24%, significantly outperforming conventional technologies by reducing electrical losses.
Extended Lifespan
TopCon technology reduces degradation rates, offering better long-term performance and a slower efficiency decline over the module's lifetime.
Better Temperature Performance
Lower temperature coefficients mean TopCon panels maintain better performance in hot conditions, ideal for real-world applications.
Cost Effectiveness
While initially more expensive, TopCon's higher energy yield and longevity deliver superior ROI and lower levelized cost of electricity (LCOE).
Bifacial Capability
TopCon's design enables efficient bifacial modules that capture light from both sides, increasing energy yield by up to 30% in optimal conditions.
Versatile Applications
Ideal for both residential and utility-scale installations, TopCon modules excel in space-constrained applications where maximizing energy per area is critical.
How TopCon Technology Works
-
1
Tunnel Oxide Layer
An ultra-thin tunnel oxide layer (typically ~1.5nm thick) is deposited on the rear surface of the cell. This layer allows electrons to "tunnel" through while minimizing recombination losses.
-
2
Polysilicon Layer Deposition
A doped polycrystalline silicon layer is deposited on top of the tunnel oxide, creating a sophisticated electron-selective or hole-selective contact structure.
-
3
Metallization
Advanced metallization techniques are applied to create electrical contacts that efficiently collect the generated current with minimal resistive losses.
-
4
Advanced Cell Integration
The completed TopCon cells are integrated into modules using state-of-the-art interconnection technologies that maximize reliability and performance.
