Difference between MONO PERC and TOPCON Solar Cells
Two unique technologies—MONO PERC (Passivated Emitter Rear Cell) and TOPCON (Tunnel Oxide Passivated Contact)—are used to make solar cells. Here’s an instant comparison between the two.
Mono PERC:
- Structure: Passivated emitter on the front, passivated rear contacts.
- Efficiency: High, typically 20% to 24%.
- Cost: Relatively cost-effective due to established manufacturing.
- Light Absorption: May have limited light absorption.
- Temperature Sensitivity: Less sensitive to high temperatures.
- Reliability: Well-established track record.
TOPCON:
- Structure: Tunnel oxide passivated contacts on both front and rear sides.
- Efficiency: Very high, often exceeding 24%.
- Cost: Generally, more expensive due to advanced technology.
- Light Absorption: Enhanced light absorption, especially in low-light conditions.
- Temperature Sensitivity: Designed to be less temperature-sensitive.
- Reliability: Promising but may lack extensive long-term data.
In conclusion, TOPCON excels in efficiency and light absorption whereas Mono PERC is affordable and dependable. The decision is based on the requirements of the project, Budget, and the desired performance traits.
