Abstract

The invention provides a high-power light condensation solar photoelectric hydrogen conversion device. The high-power light condensation solar photoelectric hydrogen conversion device comprises a light condensation solar power generation module and an electrolytic hydrogen production module; a main output electrode of the light condensation solar power generation module is correspondingly connected with a main input electrode of the electrolytic hydrogen production module; and the light condensation solar power generation module includes at least one light condensation solar power generation module. The light condensation solar power generation module is directly connected with the electrolytic hydrogen production module for converting optical energy, electric energy and chemical energy. Compared with a traditional optical energy-electric energy-chemical energy-electric energy-optical energy conversion process, a chemical energy-electric energy conversion phase in middle is omitted, so that the loss of electric energy in the conversion phase is reduced, and the solar energy-optical energy conversion efficiency is improved. The device is low in cost and high in efficiency, can realize mass production of efficiency of converting photoelectric energy to hydrogen energy, and can serve as a hydrogen source device to be applied to equipment with hydrogen as energy.

Description

technical field [0001] The invention relates to the technical field of solar photoelectric hydrogen production, in particular to a high-power concentrated solar photoelectric hydrogen conversion device. Background technique [0002] With the development of the global economy and the growth of population, people's demand for energy is also increasing. At present, fossil fuels represented by petroleum and coal are still the main sources of energy. However, due to the non-renewability and limited reserves of fossil fuels, the increasing energy demand has also caused serious energy crises and environmental pollution. Therefore, the development prospect of hydrogen as a green energy is very bright, and people have been making unremitting efforts in the development and utilization of hydrogen energy. [0003] Among the existing traditional hydrogen production methods, hydrogen production by electrolysis of water is a mature hydrogen production method. The device is simple and the...
