The optical characteristics of a pyramid-textured surface and hence their impact on the solar cell performance strongly depend on different parameters like pyramid density, height, and homogeneity. 14 To decrease pyramid height, different approaches are possible, such as decreasing etching time, increasing KOH concentration, or adding an increased …

Pulsed laser ablation is increasingly being applied to locally open the rear dielectric layer of advanced silicon wafer solar cell structures, such as aluminum local back surface field solar cells. We report that the laser ablation process on the rear surface of the solar cell at a relatively low laser fluence can cause undesirable spallation at the front surface which …

Abstract The efficiency of solar cells strongly depends on their thickness. Therefore, it is important to study the dependence of the photoelectric parameters of solar cells on the thickness.

Texturing is used to reduce the reflection of light from the front surface and to improve light trapping in a solar cell. The first objective of texturing is to minimise the front-surface reflectance so that more photons remain, which can be absorbed by the solar cell resulting in a larger short-circuit current density, J sc .
Surface texturing is performed on a Si substrate to reduce the reflectance at the front side and lengthen the light passage in the solar cell such that light can be absorbed and converted to charge carriers, thereby enabling a thin wafer.
Textured Thin-film Solar Cell Simulation Texturing is often used to improve light trapping in thin film solar cells. ... (TMM) ignores the effects of surface texturing. Finite difference time methods could also be used but …
