Abstract

The invention discloses a fluorescent nuclear battery comprising a sealed shell, a radiation source, a semiconductor photovoltaic module and fluorescent layers. Each fluorescent layer includes a glass substrate and a fluorescent powder layer arranged on the glass substrate. A rotating bracket is arranged inside the sealed shell, and a rotating shaft of the rotating bracket passes through the center of the sealed shell. The semiconductor photovoltaic module is fixed on the inner wall of the sealed shell. The radiation source is fixed in the center of the sealed shell through the rotating shaft. The fluorescent layers are arranged between the semiconductor photovoltaic module and the radiation source, and the fluorescent layers are symmetrically fixed on the rotating bracket. The fluorescent powder layers of the fluorescent layers are oppositely arranged, and the fluorescent powder layers of at least one pair of fluorescent layers face the radiation surface of the radiation source. As a double-sided radiation source or a block-shaped or rod-shaped radiation source is adopted, the radiation surface of the radiation source is enabled to at least act on two fluorescent layer units, the output power of the battery in unit area is effectively improved, and the sustainable service life of the battery is prolonged.

Description

Technical field [0001] The invention belongs to the fields of nuclear physics, nuclear energy applications and micro energy, and specifically relates to fluorescent nuclear batteries. Background technique [0002] A nuclear battery, also known as an isotope battery, is a device that uses energy-carrying particles (such as α, β particles, and γ rays) released by the decay of a radioactive source or the heat generated by the decay to convert into the required electrical energy. Due to its advantages such as long life, small size, light weight, strong environmental adaptability, wide operating temperature range and stable output power, it is used in many fields such as ultra-low power devices and automatic control systems, especially those that are difficult to replace and repair. The environment has great potential use value. [0003] In 1957, Elgin-Kidde was first used based on the "Beta-Voltaic Effect" phenomenon (Rappaport, 1953) 147 Pm, phosphors and silicon photocells form isot...
