C-14 powered dye-sensitized betavoltaic cells

Abstract

A dye-sensitized betavoltaic cell is developed for the first time, which utilizes radioisotopic carbon, composed of nano-sized quantum dots, and ruthenium-based dye sensitized TiO₂ as electrodes. In this cell, emitted beta radiations are absorbed by the dye rather than TiO₂, which resulted in enhanced performance compared to the pristine betavoltaic cell.
