Amorphous Solar Cells

Overview

Study of surface inhomogeneities and characteristics of amorphous silicon solar cells using laser scanning techniques. This research examines the correlation between surface morphology, optical properties, and photovoltaic performance.

Laser-based scanning methods enable non-contact, high-resolution mapping of surface features critical to cell efficiency.

  • Laser Scanning Study of Surface Inhomogeneities in Amorphous Silicon Solar Cells

    Abstract

    A laser scanning technique has been developed and applied to map surface inhomogeneities in amorphous silicon (a-Si:H) solar cells. The method provides high-resolution spatial mapping of optical and electrical properties, revealing correlations between surface morphology and photovoltaic performance.

    Key Results

    Spatial variations in light absorption and photoluminescence intensity were correlated with local variations in fill factor and conversion efficiency. The technique enables identification of degraded regions and optimization of deposition parameters.
