Solar Power Without Solar Cells Another 3D-solution of ZL Wang and his team from Georgia Institute of Technology The energy conversion efficiency of three-dimensional dye-sensitized solar cells (DSSCs) in a hybrid structure that integrates optical fibers and nanowire arrays is greater than that of a two-dimensional device. Internal axial illumination enhances the energy conversion efficiency of a rectangular fiber-based hybrid structure by a factor of up to six compared to light illumination normal to the fiber axis from outside the device.
