Embodiment 1

[0032] Fabrication of Upright Organic / Polymer Photovoltaic Devices

[0033] Pre-cut the ITO conductive glass with a sheet resistance of ~20 Ω / □ into 15mm×15mm square pieces. Use acetone, special detergent for micron-sized semiconductors, deionized water, and isopropanol to clean ultrasonically in sequence, and then place it in a constant temperature oven for later use after purging with nitrogen. Before use, clean ITO sheets were bombarded with plasma in an oxygen plasma etcher for 10 minutes. And with PEDOT:PSS aqueous dispersion (aqueous solution with a mass concentration of 1%, purchased from Bayer Company), the buffer layer was spin-coated at a high speed with a homogenizer (KW-4A), and the thickness was determined by the rotational speed. A surface profiler (Tritek Company Alpha-Tencor 500) was measured and monitored, and the final film thickness was 40 nm. After film formation, remove solvent residue and hard film in a constant temperature vacuum oven.

[0036] Fabrication of Inverted Organic / Polymer Photovoltaic Devices

[0037] Pre-cut the ITO conductive glass with a sheet resistance of ~20 Ω / □ into 15mm×15mm square pieces. Use acetone, special detergent for micron-sized semiconductors, deionized water, and isopropanol to clean ultrasonically in sequence, and then place it in a constant temperature oven for later use after purging with nitrogen. Before use, clean ITO sheets were bombarded with plasma in an oxygen plasma etcher for 10 minutes. Then spin-coat a layer of zinc acetate solution on the ITO conductive glass, and then heat treatment at 200 degrees Celsius to form a layer of zinc oxide. The natural pigment derivative copper chlorophyllin sodium salt solution dissolved in methanol solvent is prepared on the zinc oxide film layer by spin coating to form a cathode interface modification layer.

Abstract

The invention discloses an organic / polymer solar battery device and a preparation method of the organic / polymer solar battery device. According to the solar battery device, two kinds of structures are included, wherein in the first kind of structure, the solar battery device is composed of a substrate, an anode layer, an anode modified layer, an active layer, a cathode modified layer and a cathode layer from bottom to top; in the second kind of structure, the solar battery device is composed of a substrate, a cathode layer, metallic oxide, a cathode modified layer, an active layer, an anode modified layer and an anode layer from bottom to top; the anode modified layer is natural pigment or natural pigment derivatives. The preparation method comprises the step that the natural pigment and the natural pigment derivatives with water / alcohol solubility are manufactured between the active layer and a cathode of a positive position type or inverted type photovoltaic device through a solution processing method, so fill factors of an organic / polymer solar battery are increased, the open-circuit voltage of the organic / polymer solar battery is increased, and the energy conversion efficiency is improved. Based on application of the natural pigment and the natural pigment derivatives, the organic / polymer solar battery device with high photovoltaic performance can be obtained.
