Systems and methods for thermophotovoltaics with storage

This invention describes a system that turns heat into electricity using a special kind of solar cell. First, a device heats a fluid. This hot fluid can either store its heat in a material for later use or immediately send it to a power block. In the power block, the hot fluid causes a component to glow and emit light, which is then converted into electricity by a thermophotovoltaic device. The heat can be generated by electricity, chemical reactions, or concentrated sunlight.

Why it matters: Since 2014, thermophotovoltaic (TPV) device efficiencies have significantly improved, making the conversion of stored heat to electricity more viable. Advances in high-temperature thermal storage materials also enhance the system's practicality.
