Embodiment 1

[0032] Embodiment 1 Preparation of upright organic / polymer photovoltaic device

[0033] ITO conductive glass, square resistance ~ 20Ω / m 2 , pre-cut into 15mm x 15mm square pieces. Use acetone, special detergent for micron-sized semiconductors, deionized water, and isopropanol to ultrasonically clean in turn, and place in a constant temperature oven at 80°C for later use. Before use, clean ITO sheets were bombarded with plasma in an oxygen plasma etcher for 4 minutes. And with PEDOT:PSS water dispersion (mass concentration is 1% aqueous solution, purchased from Bayer company), buffer layer is spin-coated with glue homogenizer (KW-4A) at high speed, and thickness is determined by rotating speed, with surface profilometer (Tritek company Alpha-Tencor500 type) is measured and monitored, and the final film thickness is 40 nanometers. After the film is formed, it is annealed at 120° C. for 20 minutes in the air environment to remove residual moisture.

[0035] Embodiment 2 Preparation of inverted organic / polymer photovoltaic device

[0036] ITO conductive glass, square resistance ~ 20Ω / m 2 , pre-cut into 15mm x 15mm square pieces. Use acetone, special detergent for micron-sized semiconductors, deionized water, and isopropanol to ultrasonically clean in turn, and place in a constant temperature oven at 80°C for later use. Then spin-coat a layer of zinc acetate solution on the ITO conductive glass, and then heat it at 200 degrees Celsius for one hour to make it completely hydrolyzed to form a zinc oxide layer. A polyvinylpyridine solution dissolved in an ethanol solvent is prepared on the zinc oxide film layer by spin coating to form a cathode interface modification layer.

Abstract

The invention discloses a water/alcohol-soluble non-conjugated polymer interface material, an organic solar cell device and a preparation method thereof, and belongs to the field of organic/polymeric photovoltaic technologies. Specifically, polyvinyl pyridine and a derivative thereof are applied to an organic/polymeric solar cell as a cathode interface modification layer. Water/alcohol soluble polyvinyl pyridine and the derivative thereof are made between the active layer and the cathode of a normal or inverted organic/polymeric photovoltaic device through solution processing, and therefore, the filling factor, open-circuit voltage and energy conversion efficiency of the organic/polymer solar cell are improved. Based on the application of polyvinyl pyridine and the derivative thereof, an organic/polymeric solar cell device with high photovoltaic performance can be obtained.

Description
