How does the solar cell work?
In passivated silicon heterojunction solar cells, the reduction of surface recombination allows the Auger effect to come to the fore. In other words, high surface passivation achieved quality results in a significant increase in fill factor and energy conversion efficiency.
Surface passivation is a crucial process in the fabrication of silicon heterojunction solar cells. It involves applying thin layers of special materials to the surface of the solar cell to reduce energy losses caused by recombination of charge carriers at the interface between silicon and other materials. By reducing surface recombination, passivation improves the efficiency of the solar cell, allowing it to more efficiently capture and convert sunlight into electricity.
With high-quality surface passivation, the Auger effect becomes more prominent. The Auger effect is a phenomenon in which the recombination of charge carriers in the presence of impurities or defects in the structure of the material generates additional heat, resulting in energy losses. However, when surface passivation is effective and surface recombination is minimized, the Auger effect becomes more significant, boosting solar cell performance.
Advanced solar energy solution
The increase in the fill factor, which measures the solar cell's ability to effectively collect charge carriers generated by sunlight, and the improvement in energy conversion efficiency are direct results of this process. This means that passivated silicon heterojunction solar cells can achieve higher energy efficiency and improved performance compared to conventional solar cells.
Therefore, by optimizing surface passivation and harnessing the Auger effect, silicon heterojunction solar cells can offer an advanced solution for solar power generation, further boosting the efficiency and viability of renewable energy.
