Nuclear energy is considered a suitable and eco-friendly alternative for combating the rising greenhouse gases in the atmosphere from excessive fossil fuel consumption. Betavoltaic battery is a form of nuclear technology that utilizes the decay energy of β-emitting radioisotopes to produce electrical power. Owing to its long shelf life, high specific energy density, and ability to work under extreme conditions, it has been a subject of considerable research attention in the past few years. Despite significant research on betavoltaic battery, several impediments to realizing high energy conversion efficiency and maximum power density have yet to be overcome. This Review Article comprehensively discusses the challenges and recent research progress of betavoltaic battery development. First, promising strategies for improving betavoltaic battery performance, theoretical principles, and equations for quantifying betavoltaic battery efficiency are discussed. Then a thorough overview of several β-radiation absorbing materials, such as traditional semiconductors, metal oxides, and organic/inorganic materials, is explored. Finally, the outlook for betavoltaic battery is discussed before concluding the review.

Wide band gap TiO2 with high light absorption coefficient, high crystallinity, and high carrier mobility is widely used to assemble ultraviolet photodetectors (UV PDs) with high performance. Based on the strong attractiveness from its advantages such as high stability and excellent photoelectric properties, the construction of high-performance TiO2-based UV PDs has been extensively developed. Conducting polymers with high carrier mobility and good electrical conductivity can make up for the shortcomings of TiO2-based UV PDs to achieve efficient TiO2-based UV PDs with high photoelectric performances. In this paper, we present an in-depth review of the preparation process of TiO2 with conducting polymers and their complexes and introduce the principle, classification, and main evaluation parameters of UV PDs. In addition, this paper reviews that TiO2/polymer UV PDs have exhibited different optoelectronic properties (responsivity, switching ratio, detectivity, response time, etc.). Finally, it looks at the future of TiO2-based UV PDs research and the major challenges that need to be addressed, particularly that of further functional applications. This review lays the foundation for solving current technical problems and provides insights into the preparation of a more efficient TiO2/conductive polymer for future photovoltaic applications.

Betavoltaic batteries, as a kind of ultimate battery, have attracted much attention. ZnO is a promising wide-bandgap semiconductor material that has great potential in solar cells, photodetectors, and photocatalysis. In this study, rare-earth (Ce, Sm, and Y)-doped ZnO nanofibers were synthesized using advanced electrospinning technology. The structure and properties of the synthesized materials were tested and analyzed. As betavoltaic battery energy conversion materials, the results show that rare-earth doping increases the UV absorbance and the specific surface area and slightly reduces the band gap. In terms of electrical performance, a deep UV (254 nm) and X-ray source (10 keV) were used to simulate a radioisotope β-source to evaluate the basic electrical properties. Among them, the output current density of Y-doped ZnO nanofibers can reach 87 nA•cm −2 , which is 78% higher than that of traditional ZnO nanofibers, by deep UV. Besides, the photocurrent response of Y-doped ZnO nanofibers is superior to that of Ce-doped and Sm-doped ZnO nanofibers by soft X-ray. This study provides a basis for rare-earthdoped ZnO nanofibers as energy conversion devices used in betavoltaic isotope batteries.
