Cover Story: Three-dimensional flexible solar fabrics based on hydrogenated amorphous silicon (a-Si:H) thin film solar cells were prepared and characterized. A glass fiber fabric with a polytetrafluoroethylene (PTFE) coating proved to be a suitable textile substrate. Interwoven metal wires enabled an integrated electrical interconnection. The best solar cells showed an efficiency of 3.9%, with an open-circuit voltage of 876 mV and a short-circuit current density of 11.4 mA/cm2. The high series resistance limited the fill factor to 39%. The potential of the textile solar cells was demonstrated by the pseudo fill factor of 79% achieved when neglecting the series resistance, resulting in a pseudo efficiency of 7.6%. When four textile solar cells were connected in a series, an open-circuit voltage of about 3 V was achieved. View this paper
