Effect of Textured Tin Oxide and Zinc Oxide Substrates on the Current Generation in Amorphous Silicon Solar Cells

    Research output: Contribution to conferencePaper

    Abstract

    We evaluate material properties of a number of textured SnO2 and ZnO substrates and their effect on current generation in a-Si. Most of these TCOs have been used by others for a-Si device research of module fabrication. Bulk optoelectronic and structural properties are reported for seven TCO films with haze from 1 to 14%. Our results show that increasing haze above~5% has limited effectivenessfor increasing the generation at long wavelengths. In presently available textured ZnO, current generation is about 0.6 mA/cm2 greater than in textured SnO2. There may be greater advantages to using ZnO in multijunction devices since much thinner i-layers may be used to give the same Jsc with improved stability, shorter deposition time and less GeH4 usage.
