AI Technical Summary
In existing solar cells, uneven electrode morphology leads to low photoelectric conversion efficiency and high cost, making it difficult to balance cell efficiency and cost.
The collector electrode is designed to ensure good uniformity of the metal crystal depth extending in the doped silicon layer. By controlling the depth difference of the metal crystal to within 5% and optimizing the width and height distribution of the electrode, good ohmic contact and uniform resistance distribution are ensured.
It improves the photoelectric conversion efficiency of solar cells, reduces contact resistance and bulk resistance, reduces the amount of electrode paste used, lowers production costs, and improves the stability and reliability of the cells.
