Problems solved by technology

At present, polythiophene derivatives (PEDOT:PSS) are widely used in optoelectronic devices because of their easy preparation at low temperature, high light transmittance in the visible light range, good electrical conductivity and excellent film-forming properties. But this kind of material also has many deficiencies: 1.PEDOT:PSS aqueous solution becomes strong acidity, can cause corrosion to ITO electrode material, make battery stability weaken; 3. The light transmittance is not high, resulting in low current density of battery devices
[0004] Although perovskite solar cells have the advantages of low cost, the problems of poor stability and low photoelectric conversion efficiency have always been important technical bottlenecks restricting their wide application.

Abstract

The invention discloses a pervoskite thin-film solar cell taking cuprous rhodanide as a hole transporting layer, and a preparation method thereof. The pervoskite thin-film solar cell is characterizedin that a structure of the solar cell orderly comprises a transparent conducting substrate 1, a graphene and strontium titanate composite thin-film 2, a pervoskite thin-film 3, a graphene oxide thin-film 4, a cuprous rhodanide thin-film 5, and a metal electrode 6 from bottom to top. The solar cell disclosed by the invention has the advantages that the charge compounding of an interface can be effectively reduced by using the graphene and strontium titanate composite thin-film, and the short-circuit current of the cell is improved; the graphene oxide thin-film is used as a buffer layer to further suppress the carrier compounding and improve the photoelectric conversion efficiency of the cell; the cuprous rhodanide not only has high hole transporting capacity, but also has good light-transmittance and excellent heat stability at a visible light area and a near infrared area, so that the stability and the photoelectric conversion efficiency of the pervoskite solar cell can be further improved by taking the cuprous rhodanide as the hole transporting layer material.
