摘要

This study presents the impact of surface modification on bifacial solar cells through single-pulse drilling to enhance efficiency and optical characterisation. A single-pulse laser operates at a wavelength of 1.06 μm, and the microsecond length is a function of its energy and structure setup. The front surface is drilled with two laser energy settings, namely, 23.5 W and 39.6 W, to create a range of micro-holes with distinct depths, widths and crys-tallographic defects. The modification of the front laser surface has enhanced current density and effectiveness by capturing light in the crystallisation region and the inner region of the micro-holes. Cell topography shift reduces the recombination of electron/hole on the surface. The rear surface registers efficiency digression because of a crystallographic defect that increases optical losses that boost the recombination of hole/electron. The efficiency of the cell with low-power front surface laser drilling increases 1.38%, but that of the cell with low-power back surface laser drilling drops 2.12%. High-power laser drilling increases 1.46% for the front surface and decreases 1.36% for the back surface. Optical characterisation via infrared transmission shows that light increment at a wavelength of 1100 nm is transmitted through the laser drill's micro-holes. The different depths and widths of the micro-holes determine the light transmission rate that can travel to the back surface. The growth of holes improves the light-scattering and absorption regions, affecting cell efficiency.
