Abstract
A method of fabricating organic solar panels with transparent contacts. The method uses a layer-by-layer spray technique to create the anode layer. The method includes placing the substrate on a flat magnet, aligning a magnetic shadow mask over the substrate, applying photoresist to the substrate using spray photolithography, etching the substrate, cleaning the substrate, spin coating a tuning layer on substrate, spin coating an active layer of P3HT/PCBM on the substrate, spray coating the substrate with a modified PEDOT solution, and annealing the substrate.
Claims20
A method for fabricating an organic inverted solar photovoltaic cell, comprising the steps of:
- obtaining a substrate comprising a substrate coated with indium tin oxide;
- applying photoresist to a substrate by spray photolithography;
- forming an interstitial layer by spray coating a layer of on top of the indium tin oxide coating;
- forming an active layer by spray coating a layer of poly-3(hexylthiophene) and [6,6]-phenyl C61-butyric acid methylester disposed on the interstitial layer;
- forming an anodic layer by spray coating a layer comprising poly (3,4) ethylenedioxythiophene:poly-styrenesulfonate doped with 5 vol. % of dimethylsulfoxide, wherein the anodic layer is disposed on the active layer;
- and
- annealing the layers on the substrate.
The method of claim 5, wherein the anodic layer is about 500 nm thick, about 1 μm thick, 100 nm thick, 500 nm thick, or 1 μm thick.
