The provided photoelectricity transducer has simple structure, high transducing efficiency, well stability, and no pollution. The related manufacture method is simple, and frees to the vacuum environment for low cost.

Description

technical field [0001] The invention belongs to the field of photoelectric material and product manufacturing, and relates to a material and product and a manufacturing method thereof, in particular to a photoelectric conversion device and a manufacturing method thereof. Background technique [0002] The sun is a hot gaseous sphere, a huge, long-lasting, inexhaustible source of energy. As a clean energy source without any pollution, solar energy has attracted more and more attention and great interest from all over the world. [0003] Human beings have a long history of utilizing solar energy. As early as the Warring States period more than 2,000 years ago, our country knew to use steel four-sided mirrors to focus sunlight to ignite fires; use solar energy to dry agricultural and sideline products. So far, the utilization of solar energy has become increasingly widespread, including solar thermal utilization, photovoltaic utilization of solar energy and photochemical utili...
