Embodiment 1

[0031] [1] The ITO glass was repeatedly scrubbed with acetone, isopropanol, and deionized water in sequence, ultrasonicated for 10 minutes, and then dried;

[0032] [2] At room temperature, add a mixed solution of 30ml of ethanol, 10ml of deionized water, and 2ml of hydrochloric acid with a concentration of 0.28mol / l dropwise into a solution containing 10ml of tetrabutyl titanate, 60ml of ethanol, and 5ml of acetylacetone , and accompanied by vigorous stirring for 2 hours, and then prepared TiO 2 Sol.

[0033] [3] TiO 2 The sol was spin-coated on the ITO glass at a speed of 3000rpm, placed in a muffle furnace, and sintered at 450°C for 2 hours. After sintering, nc-TiO was formed on the ITO glass. 2 layer with a thickness of 30 nm.

[0034][4] The chlorobenzene solution of P3HT and PCBM with a mass ratio of 1:0.8 (concentration of 18 mg / ml) was spin-coated on ITO / nc-TiO at a speed of 1280 rpm. 2 Then put the ITO into a vacuum oven and dry it at 150° C. for 10 minutes to obt...

Abstract

The invention belongs to the technical field of organic photoelectric devices, and particularly relates to a semitransparent inverse organic solar cell and a preparation method thereof. The semitransparent inverse organic solar cell device comprises a substrate, a transparent cathode, an organic photoelectric conversion layer and a transparent anode in turn, wherein the transparent anode adopts a multilayer structure and comprises an anode buffer layer, a metal thin layer and an anti-reflection film. By introducing the anti-reflection film, the energy conversion efficiency of the semitransparent inverse organic solar cell can be improved; and by changing the thickness of the anti-reflection film, the transmission spectrum of the transparent anode can be adjusted. The prepared semitransparent inverse organic solar cell has the characteristics of high efficiency and simple process.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric devices, and in particular relates to a translucent organic solar cell with an inverted structure and a preparation method thereof. Background technique [0002] A solar cell is a device that converts light energy radiated by the sun into electrical energy. At present, the energy harvesting efficiency of silicon solar cells has reached 24%. It is close to the upper limit of 30% of the theoretical calculation value, but its production process is complicated, and the mature technology makes the photoelectric conversion efficiency basically reach the limit value, further improvement is limited, and the material itself is not conducive to reducing costs. These reasons limit its large-scale civilian use change. In contrast, organic solar cells have the following characteristics: structural improvement at the molecular level is possible; there are many ways to change and improve the spec...
