When there is no sun, solar energy needs to be stored in batteries or through a photocatalysis process.
Russian scientists from the Moscow Institute of Physics and Technology (MIPT), the Technological Institute for Superhard and Novel Carbon Materials (TISNCM), and the National University of Science and Technology MISIS have upgraded the design of a nuclear battery that produces power from the beta decay of nickel-63, a radioactive isotope.
Although it may appear as if batteries come in every size & shape, as electronic devices, they become smaller without any decrease in their energy & power demands. Hence, they pose challenges to develop batteries that can fit into smaller spaces without affecting performance.
For the last many years, the commercialization of perovskite photovoltaic cells has gained immense attention. At present, the hot news is that devices developed by using these materials can transform solar energy into electricity with a higher efficiency like never before.
Rechargeable batteries developed from magnesium, in place of lithium, possess the ability to increase the driving range of the electric vehicle by loading more energy into small-sized batteries. However, unexpected chemical obstacles have decelerated the scientific advancement.
Researchers from RIKEN and the University of Tokyo have created a new type of ultra-thin photovoltaic device, coated on both sides with waterproof and stretchable films, which can continue to provide electricity from sunlight even after being immersed in water or being compressed and stretched.
For the first time, Researchers from the Helmholtz-Zentrum Berlin (HZB) have developed a nanomaterial produced from nanoparticles of a titanium oxide compound—namely, Ti4O7 (having an exceptionally large surface area)—and analyzed its usage as a cathode material in lithium-sulfur batteries.
A new material capable of reducing signal losses in photonic devices has been developed by engineers at the University of California San Diego. This advancement has the potential to increase the efficiency of a number of light-based technologies including lasers, fiber optic communication systems, and photovoltaics.
A simple solution-based electrical doping method could help decrease the cost of organic electronic devices and polymer solar cells, potentially broadening the usage for these technologies.
Researchers from the Technion-Israel Institute of Technology have created an innovative technology that could improve photovoltaic (PV) cell efficiency by nearly 70%. This breakthrough development could help to overcome current technological limitations to harnessing solar power to fulfill the global energy consumption demands.
