In this contribution, amorphous silicon thin-film solar cells on textile glass fiber fabrics

for smart textiles are prepared and the photovoltaic performance is characterized.

These solar cells on fabrics delivered open circuit voltages up to 883 mV. This shows

that shunt-free contacting of the solar cells was successful, even in case of non-planar

fabrics. The short-circuit current densities up to 3.7 mA/cm² are limited by transmission

losses in a 10 nm thin titanium layer, which was used as a semi-transparent contact.

The low conductivity of this layer limits the fill factor to 43.1%. Pseudo fill factors,

neglecting the series resistance, up to 70.2% were measured. Efficiencies up to 1.4%

and pseudo efficiencies up to 2.1% were realized on textile fabrics. A transparent

conductive oxide could further improve the efficiency to above 5%.
