Main Advantages: Higher ROI: In our rooftop tests, TOPCon generated ~4.7% more energy annually than PERC, even after accounting for a ~3% higher CAPEX. Better temperature performance: With a temperature coefficient around -0.3%/°C (vs. PERC’s -0.37%/°C), TOPCon is more resilient in hot climates.
Their production process is more streamlined compared to other types of cells, resulting in excellent cost control. They mainly employ BSF (Back Surface Field) and PERC technology routes. The mass production conversion efficiency of PERC cells has reached 23.5%, close to the theoretical limit of 24.5%.
PERC (Passivated Emitter and Rear Cell) technology builds on traditional crystalline silicon solar cells by adding a rear passivation layer. This layer reflects unabsorbed light back into the wafer and reduces electron recombination, thereby increasing efficiency. Key Features: Efficiency: Mass-production cells typically achieve 20–22%.
From these tests, I noticed a pattern: TOPCon performs more consistently under high-temperature and low-light conditions, while BC excels in aesthetics and power density, though at a higher CAPEX. How Do These Technologies Actually Work? PERC (Passivated Emitter and Rear Cell): This technology adds a rear passivation layer to reduce recombination.
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
