Advantages and Disadvantages of PERC Cells
Let's take a look at the advantages and disadvantages of PERC cells.
Advantages:
PERC cells are currently the most mainstream technology on the market, offering high industrialization efficiency and low production costs. By introducing a silicon oxide thin film on the rear of the cell, it enhances light absorption and electron collection efficiency at the back of the cell.
Disadvantages:
The theoretical efficiency limit of PERC cells is relatively low (24.5%), and there is a light-induced degradation issue, which is especially prominent in polycrystalline PERC cells.
Technological Maturity:
PERC technology is highly mature, but with the upgrade and iteration from p-type to n-type technology, PERC technology is facing a reduction in market share.
Cost-Effectiveness:
PERC cells have a cost advantage, as their cost is similar to that of conventional cells. However, since there is limited room for efficiency improvement, they may face asset depreciation and obsolescence risks in the future.
Market Demand:
Once the dominant technology in the market, PERC cells are now gradually being replaced by new n-type cell technologies, such as TOPCon, due to technological advancements.
