Abstract

The invention discloses a photo-electrochemical cell with a needle electrode and a manufacturing method thereof. The cell at least comprises: a working electrode, a counter electrode, an electrolyte layer and a light-sensitive layer. The working electrode is a needle electrode which is formed by a semiconductor film and possesses a needle structure. The needle electrode is prepared through a sol-gel method at a low temperature so that a specific surface area of the needle electrode can be increased. More dyes can be adsorbed. An electronic conductivity rate can be raised so as to improve a photoelectric current and a photoelectric conversion efficiency.

Description

technical field [0001] The invention relates to a solar cell, in particular to a photochemical solar cell with needle-shaped electrodes and a module thereof. Background technique [0002] From the 20th century to the 21st century, the shadow of the global energy crisis has been lingering, lurking in our lives and breaking out at any time. After the Kyoto Protocol took effect, the world is committed to the research and development and creation of various alternative energy sources, among which solar energy is the most active field for the development and utilization of new energy sources. It is estimated that the energy irradiated by the sun on the earth's surface is about one million times that consumed by all people on the earth every year, that is, if one percent of the solar energy can be fully utilized and converted into electricity to meet our needs. [0003] Solar cell A device that converts solar energy directly into electricity. In the 1970s, silicon solar cells f...
