AI Technical Summary

Technical Problem

The photoelectric conversion efficiency of existing solar cells is low, which affects their promotion and application.

Method used

An interpolation layer is arranged between the light absorption layer and the electron transport layer. The interpolation layer is composed of polymers with a molecular weight greater than 10 kg/mol and fullerene derivatives, which block the reaction between the electron transport layer and the light absorption layer, passivate defects on the surface of the light absorption layer, reduce stray reflections, and block the recombination of photogenerated carriers.

Benefits of technology

By setting the interlaced layer, the photoelectric conversion efficiency of the solar cell is improved, the stability of the light absorption layer is enhanced, stray reflection is reduced, and the performance of the device is significantly improved.

Abstract

The invention discloses a solar cell, a preparation method thereof and electric equipment. The solar cell comprises a light absorption layer, an interpenetrating layer and an electron transport layer, wherein the interpenetrating layer is located between the light absorption layer and the electron transport layer; the interpenetrating layer includes a polymer having a molecular weight greater than 10 kg / mol. By arranging the interpenetrating layer between the light absorption layer and the electron transmission layer, the reaction between the electron transmission layer and the light absorption layer can be blocked, defects on the surface of the light absorption layer can be passivated, stray reflection is reduced, re-compounding of photon-generated carriers is prevented, and the photoelectric conversion efficiency is improved.
