Abstract

A solar cell is disclosed. The solar cell includes a transparent conductive layer formed on a substrate, microstructures protruding vertically aslant from a surface of the transparent conductive layer, an electron transport layer configured to cover the microstructures and formed of an electron transport metal oxide, a light absorber adhered to inner pores and a surface of the electron transport layer, a hole transport layer configured to cover the surface of the electron transport layer and formed of a hole transport material, and an electrode formed on the hole transport layer. In the solar cell, the thickness of a light absorption layer can be maximized to obtain a high current density and high photoelectric conversion efficiency.

First claim

What is claimed is:

1. A solar cell comprising:
a substrate;
a transparent conductive layer disposed on the substrate;
microstructures extending substantially perpendicular to a surface of the transparent conductive layer;
an electron transport layer comprising an electron transport metal oxide disposed to fill at least part of space between the microstructures and cover the microstructures;
a light absorber adhered to inner pores and a surface of the electron transport la…
