As materials science, nanotechnology, and energy conversion technologies continue to advance, renewable energy technologies continue to evolve. Photovoltaic power generation has become one of the most widely used renewable energy generation technologies. However, photovoltaic cells rely on sunlight to generate electricity and cannot work under poor light intensity or dark conditions. As a new type of energy conversion technology, thermoradiative photovoltaics can generate electricity in the absence of light, and the working principle of the device is similar to that of solar cells working in reverse, providing another way for energy production. In the future, thermoradiative photovoltaics may become one of the important ways of power generation, with broad application prospects and significant development potential. This paper reviews the research progress of domestic and foreign scholars in thermoradiative photovoltaics, summarizes, and analyzes future prospects and outlooks.
