Alpha/Beta Voltaics with Poly(3-hexylthiophene) Conjugated Polymer
In connection with the NASA Space Technology Mission Directorate (STMD), the objective of the investigator of this research is to develop an efficient alpha/beta voltaic battery operating through a scintillating phosphor and an organic photovoltaic material. As opposed to conventional inorganic absorber material in alpha/beta voltaic batteries, radiation conversion in this proposed battery may operate through: an inorganic scinitillator composed of thallium-doped cesium iodide (CsI: TI) and cerium-doped yttrium aluminum garnet (Ce:YAG), and a blended polymer layer composed of Poly(3-hexylthiophene), or (P3HT), and Phenyl-C61-butyric acid methyl ester (PCBM). The investigators aim to achieve these objectives through phosphor and semiconductor polymer matching and studying the degradation of the phosphor and polymer from exposure to alpha and beta sources. The creation of this battery could prove valuable in space applications due to the expected low weight of the device, and could also reduce a reliance on current fabrication methods involving toxic materials and high temperatures.
