Electric power generation method using solar cells and photovoltaic power generation system

摘要

A photovoltaic power generation system includes a plurality of power generation panels and a power conditioner. The power generation panels and a radiation source are placed in a solar cell storage room buried typically in the ground. The radiation source includes radioactive waste generated in reprocessing of spent nuclear fuel. Each power generation panel has a phosphor member and a moderator member, which are disposed in that order on solar cells placed on a board. Radiation (for example, a gamma ray) emitted from the radiation source is injected on the power generation panel and is moderated by the moderator member. When the gamma ray with the reduced energy (below 100 keV) is injected on the phosphor member, it emits visible light. When the visible light is injected on the solar cells, electric power is generated.

主权项

1. An electric power generation method using a solar cell, the method comprising steps of:
moderating radiation by a moderator comprised of lead or tungsten and having a thickness within a range of 1 μm to 1 mm, wherein said radiation is emitted from radioactive waste as a radiation source; injecting said radiation with energy moderated by said moderator on a phosphor member and generating visible light in said phosphor member; and injecting said generated visible light on said solar cell and generating electric power in said solar cell, wherein the radioactive waste comprises Cs-137 or Sr-90.
