NOVELTY - The photovoltaic device has an array of photovoltaically active microstructures (102) each having a generally cylindrical outer periphery and a dome-shaped tip. Each of the microstructures absorbs at least 70 percent of light passing through an outer layer (110) thereof. The array of microstructures is arranged in a brush configuration. The microstructures absorb at least 99 percent of light passing through an inner surface of an outer layer thereof.    USE - Photovoltaic device used as e.g. solar/light concentrator. Can be used for charging of electronic devices such as cell phone, computer, personal digital assistant, for medium scale applications such as light weight roof-top energy for industrial and agricultural power generation, and for large applications, such as a lightweight energy source for transportation e.g. automobile, aircraft, barges.    ADVANTAGE - Enables selecting of a combination of theta rotation and initial presentation angle relative to a light source position to maximize power output. The brush configuration has flexible manufacturing options including membrane manufacturing technologies or photolithography electron-beam, low density layered mechanical scoring, microporous templated, electroplating, and electrical arcing. Allows a cell to be shaped and hardened to geometry that has maximum solar efficiency, maximum aerodynamic efficiency, maximum aesthetic appeal. Flexible units are achieved by daisy chain connection between small rigid units or from the use of a flexible substrate. Improves power generation in low light conditions, and possibly even power generation from infrared light during night time. Improves overall efficiency of the brush since one or more electrically conductive strips may extend across an array of photovoltaic devices, or portion thereof to assist in carrying electricity away from the array. Efficiency gains are more pronounced in larger arrays, and the strips are preferably very thin to block minimal light. High temperature degradation is mitigated because each component of PV cell can be sized to minimize thermal expansion and further optimized with flexible expansion joint conductive connections between PV arrays. The greater surface area of the solar brush reduces thermal heat generated under the PV solar cell more efficiently compared to the conventional planar unit. The PV brush is able to transfer energy more effectively than conventional PV cells at higher operating temperatures.
