An amorphous semiconductor composition includes 1 to 70 atomic percent iron, 15 to 65 atomic percent dysprosium, 15 to 35 atomic percent terbium, balance X, wherein X is at least one of an oxidizing element and a reducing element. The composition has an essentially amorphous microstructure, an optical transmittance of at least 50% in at least the visible spectrum and semiconductor electrical properties.

A hollow photovoltaic fiber. The hollow photovoltaic fiber includes semiconductor formed on the inner surface of a hollow tube or on a flexible substrate subsequently formed into a hollow tube. The hollow photovoltaic fiber is suitable a variety of semiconductor devices, including solar cells. Light entering the hollow photovoltaic fiber deposits energy in the semiconductor as it travel through the tube. The hollow photovoltaic fiber exhibits improved energy conversion efficiency over planar thin film solar cells due to the large semiconductor surface area and longer light travel path provided by the tube. Embodiments of the hollow photovoltaic fiber are lightweight and flexible allowing the creation of non-planar solar cells and the applications for solar cells to extend into such areas as the manufacture of photovoltaic textiles or photovoltaic non-woven fabrics.
