Abstract

The invention discloses a solar cell, which comprises a cathode assembly, an anode assembly, a sealant and an electrolyte, wherein the sealant is used for assembling the cathode assembly and the anode assembly together to form a closed space; the electrolyte is accommodated in the closed space; the cathode assembly comprises a lower transparent conducting substrate, a nano-oxide semiconductor thin film formed on the lower transparent conducting substrate and dye stuff attached onto the surfaces of nano particles in the nano-oxide semiconductor thin film; the anode assembly comprises an upper transparent conducting substrate, an anode layer formed on the upper transparent conducting substrate and a patterning CdTe layer with an opening; the nano-oxide semiconductor thin film and the anode layer are arranged oppositely and are contacted with the electrolyte; and the anode layer is arranged in the opening of the CdTe layer. The solar cell disclosed by the invention is high in photoelectric conversion efficiency.

Description

technical field [0001] The present invention relates to solar cells and methods of manufacturing the same, and more particularly, to dye-sensitized solar cells (DSSCs) and methods of manufacturing the same. Background technique [0002] French scientist Henri Becqμerel first observed the phenomenon of photoelectric conversion in 1839, but it was not until the advent of the first practical semiconductor solar cell in 1954 that the idea of ​​"converting solar energy into electrical energy" really became a reality. In the initial development stage of solar cells, the materials used are generally narrow band gap semiconductor materials with certain absorption in the visible region, so this kind of solar cell is also called semiconductor solar cell. [0003] Although the ability of wide bandgap semiconductors to capture sunlight is very poor, attaching appropriate dyes to the surface of semiconductors can also convert solar energy into electricity by virtue of the strong absorpti...
