Embodiment Construction
[0012] Roll flexible nano-thin films of silicon into figure 2 as shown. followed by figure 1 A low concentration of radioactive element rods placed in the figure 2 in the flexible nano-thin film silicon multi-layer sleeve, and finally put the two into image 3 At the same time, connect the electrode leads externally, A' is connected to the anode lead end of A, and B' is connected to the cathode lead end of B.
[0013] The working principle of the present invention is as follows:
[0014] The decay of some waste radioactive elements is used to emit high-energy photons (γ-rays) to excite electron-hole pairs in flexible nano-thin film silicon cells to generate charged carriers and then generate current.

The invention relates to a silicon cell, in particular to a flexible nano-film silicon cell based on radioactive elements; the silicon cell consists of a lead-tight tank, flexible nano-film silicon and the low concentration radioactive elements; the outermost layer is the lead-tight tank, the innermost layer is a low concentration radioactive element bar, and the intermediate layer is the flexible nano-film silicon which has a PN knot and is provided with a contact conductor that is respectively connected with an external connection lead wire of the lead-tight tank. The invention utilizes theflexible nano-film silicon to be wrapped at the periphery of the low concentration radioactive elements. Due to the disintegration of the radioactive elements, the emitted light quantum (gamma ray) has high energy and strong penetrability, and can be wrapped by the flexible nano-film silicon (having the PN knot) layer upon layer at the periphery; the outermost periphery of the light quantum is sealed by using the lead-tight tank, so that the light quantum with high energy can penetrate the film layer upon layer to achieve the aim that one light quantum can excite n electron hole pairs. The generated electron hole pairs can move directionally in the cell having the PN knot, and the energy of the light quantum with high energy is transformed into electrical energy.
Description
technical field [0001] The invention relates to a silicon battery, in particular to a flexible nano-thin film silicon battery based on radioactive elements, which uses the decay of radioactive elements to emit high-energy photons (γ-rays) to excite electron-hole pairs in the flexible nano-thin film silicon battery to generate charged current , thereby generating an electric current. Background technique [0002] At present, there are many troubles in the disposal of many discarded radioactive elements, some of which have to be buried deep in the ground, and some have to be re-refined at a high cost, so in this case, the disposal of discarded radioactive elements is a difficult and urgent task. solved problem. However, using the principle that certain radioactive elements can produce and emit high-energy photons (γ-rays) to excite electron-hole pairs in flexible nano-thin film silicon cells, a flexible nano-thin film silicon cell based on radioactive elements is manufactured...
