Request QuoteFAQs about Bc component is better than perc component
What is PERC technology?
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%.
What are PERC cells?
PERC (Passivated Emitter and Rear Cell) cells are a high-efficiency type of P-type cell. 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.
Are BC cells better than Topcon?
BC cells have clear advantages. Since there are no front-side grid lines, BC cells naturally achieve higher front-side efficiency. Considering better front-side passivation, they can improve efficiency by 0.3%-0.5% over TOPCon. BC's aesthetic appearance also makes it especially popular in distributed applications, such as residential rooftops.
Is Topcon better than PERC?
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.
