Material can turn sunlight, heat and movement Into electricity -- all at once
Extracting energy from multiple sources could help power wearable technology.
A perovskite solid-solution that exhibits tunable bandgaps in the visible light energy range is showing promising material for light absorption and conversion applications,(solar energy harvesting and light sensing).
Such a common ABO3–type perovskite structure, most widely used for ferroelectrics and piezoelectrics, enables the same solid-solution material to be used for the simultaneous harvesting or sensing of solar, kinetic, and thermal energies.
These results are considered to be a significant improvement compared to those of other compositions which could be used for the same applications. The results pave the way for the development of hybrid energy harvesters/sensors, which can convert multiple energy sources into electrical energy simultaneously in the same material.
Cement that generates Light
Carlos Rubio Ávalos of the UMSNH of Morelia, developed a cement with the capacity to absorb and irradiate light energy,
The researcher claimed that the applications are very broad, and those which stand out most are for the architectural market: facades, swimming pools, bathrooms, kitchens, parking lots, etc. It would also be useful in road safety and road signs, in the energy sector, such as oil platforms, and anywhere you want to illuminate or mark spaces that don’t have access to electricity since it doesn’t require an electrical distribution system and is recharged only with light. The durability of light-emitting cement is estimated to be greater than 100 years thanks to its inorganic nature, and its material components are easily recyclable.
