system based on a photovoltaic cell It will be able to convert heat into electricity at 40% higher efficiency than any type of conventional steam turbine. It is a heat engine without moving parts that was designed in the United States by engineers from the Massachusetts Institute of Technology and the National Renewable Energy Laboratory (NREL). This unit uses a system similar to that of solar photovoltaic panelsallowing photons to be stored passively through an incandescent source and then convert everything into electricity: According to the project detailed by the team in the scientific journal Nature, a DVT is capable of generating electricity from a heat source ranging from 1,900 to 2,400 degrees Celsius.
The researchers’ idea is to integrate a thermal photovoltaic cell inside a battery, so that the energy can be stored and used as a food source. at the moment The system has been successfully tested on a small scale But the two teams are working to implement all components into an integrated operating system to provide a viable alternative to fossil fuel power plants, Thus, decarbonization is preferred. “Thermal photovoltaic cells are the last essential step to demonstrate that thermal batteries are a viable concept”said Henry Asigon, professor of professional development in the Department of Mechanical Engineering at MIT. “This is an essential step on the road to spreading renewable energies and achieving a completely carbon-neutral grid. One of the advantages of solid-state power inverters is that they can operate at higher temperatures with lower maintenance costs due to They have no moving parts“.
As reported by MIT magazine,The hive is manufactured on the basis of three layers. The first layer captures the high-energy photons and converts them into electricity, while the low-energy photons passing through the first layer are captured by the second and converted to add the generated voltage. All photons passing through this second layer are then reflected by the mirror, back to the heat source, instead of being absorbed as waste heat.” Experiments were conducted on cells with a surface area of about one square centimeter, but to produce a grid-scale thermal battery system would need Climbing dungeon with an area of not less than 900 square meters. In general, it is a safe and highly efficient technology, able to guarantee the durability of various motors with moving parts that cannot withstand such high amounts of heat. One wonders if and how this technology, once tried in an organic way, can also find applications in this field the cars.
