Fabrication considerations in fiber-based organic photovoltaics

Fiber-Based photovoltaic cells are solar collectors that utilize internal reflectors to confine light into an organic absorber, thereby significantly enhancing absorption cross-sections of the device. The performance of the device is particularly sensitive to internal resistivity of the "optical can." Using ITO of differing thicknesses we show that can be controlled and that Jsc's that exceed planar device limits can be achieved. However, the morphology and film quality of the layers must be maintained to achieve maximum performance.
