AI Technical Summary
When existing perovskite solar cells are scaled up to large sizes, the series resistance of the transparent conductive electrode becomes too high, leading to a decrease in cell efficiency. Existing solutions cannot balance light transmittance and conductivity, and there are conflicts in the fabrication process and manufacturing sequence.
A highly conductive transparent conductive electrode is formed by etching patterned grooves on the surface of a transparent substrate and embedding metal grid lines, combined with a metal bonding layer and a metal oxide layer. The conductivity is improved by combining the metal grid lines with the metal bonding layer, and the degree of incident light scattering is adjusted by designing the geometric pattern of the metal grid lines and the thickness of the bonding layer.
It significantly improves the conductivity of the transparent electrode, reduces photocurrent loss, expands the application range of perovskite solar cells, improves the performance of cells from small to large sizes, and is compatible with low-temperature processes, making it suitable for perovskite solar cells of various sizes.
