An optical fiber includes an optical fiber core for high-power laser transmission, an optical cladding disposed radially around the optical fiber core, and at least one harvesting cell disposed axially along the optical fiber core, the harvesting cell including an anode surrounding the optical cladding, a photovoltaic layer having a polymer-based photovoltaic material disposed radially around and electrically connected to the anode, and a cathode disposed radially around the photovoltaic layer and electrically connected to the photovoltaic layer.

Disclosed is a photovoltaic device that includes a solar cell on a light transmissive substrate in the form of an array of equal diameter optical fibers laid adjacent to each other in the transversal direction of the fibers. With such an arrangement, light harvesting at high angles is improved by 30%.

We disclose herein a hetero-structure comprising: a curved material; at least one layer of a first material rolled around the curved material; at least one intermediate layer rolled on the at least one layer of the first material; and at least one layer of a second material rolled around the at least one intermediate layer.

A fabric comprising a plurality of photovoltaic filaments includes a conductive bus structure woven into the selvage edge of the fabric, providing a robust and flexible electrical connection from the positive and negative electrode leads of the photovoltaic filaments. The bus structure may be formed in segments which can include any combination of series and parallel configurations to accommodate loads requiring specified voltage and current.

A textile includes a flexible substrate and a photovoltaic tape adjacent to the flexible substrate. The textile may have at least one of the following properties: a power to weight ratio of at least 10 Watts per pound, a total weight to surface area of not greater than 500 grams/square-meters, and an interconnect located at an end of the photovoltaic tape. In an embodiment, the photovoltaic tape is rollable on a length of the photovoltaic tape. In an embodiment, the flexible substrate is foldable along a length contiguous to an outside edge of the photovoltaic tape.
