Abstract:
1. A method of fabricating a miniature organic solar array, comprising the steps of: patterning indium tin oxide onto a glass substrate; spin coating positive photoresist onto said glass substrate; soft baking said glass substrate; exposing said photoresist to a pattern of UV light using a mask and mask aligner, said mask making contact with said photoresist which is used as a stencil for said UV light; hard baking said glass substrate developing said glass substrate; etching said indium tin oxide in a mixed solution of HCL and HNO cleaning said glass substrate; placing said glass substrate in an inert environment; spin coating PEDOT:PSS onto said glass substrate; spin coating an active layer of P3HT:PCBM; removing excess P3HT:PCBM; drying said glass substrate; using a shadow mask to deposit an Aluminum cathode by Thermal Vapor Deposition, said shadow mask being aligned with said glass substrate and acting as a stencil during deposition; heating said aluminum with current and in vacuum; and annealing said solar array.
