Amorphous silicon thin-film solar cells on glass fiber textiles

•Amorphous silicon solar cells on textile glass fiber fabrics are demonstrated.•Open circuit voltages of 883mV show shunt-free contacting on non-planar fabrics.•Short-circuit current densities of 3.7mA/cm2 are limited by transmission losses.•Fill factors of 43.1% and pseudo fill factors of 70.2% show high series resistance.•Efficiencies of 1.4% and pseudo efficiencies of 2.1% realized on textile fabrics.
