HISOCEL: Improvement of front contacts morphology for enhancement of efficiency in thin film silicon solar cells

Abstract (English)

In photovoltaic market, thin film silicon modules have one of the lowest production costs. Their efficiency of about 10% is still too low for being able to capture a larger market share. The aim of project is to improve the front contacts of tandem microcrystalline & amorphous silicon solar cells to reach an efficiency of 13% by producing denser and nearly defect free silicon layers. This can be achieved by optimization of the contacts morphology, deposition parameters and thin film silicon layers density by mutual study of microstructure of deposited layers.
