The generation of power from renewable sources can now be uninterruptedly carried out round-the-clock with the emergence of anti-solar panel technology.
FREMONT, CA: While solar panels are already being used to generate energy during the day, researchers have devised anti-solar panels that are intended to generate power at night. An anti-solar panel would be warmer than the air and radiate infrared light during the dark. A regular solar cell produces energy by absorbing sunlight causing a voltage to appear across the cell. According to EcoWatch, an anti-solar cell emits light and the voltage and current flow in the opposite direction, thereby generating energy in the process.
Anti-solar panels leverage the heat difference between the atmosphere and the surface of the earth. As the amount of power coming from the sun has to be approximately equal to the amount of energy leaving the earth as thermal radiation, the amount of energy for harvesting is huge. Thus, an anti-solar power generator has the capability can help in balancing the amount of energy collected during the day and at night.
The new device, which must be made of a material that can hold extremely long-wavelength of light, utilizes a thermoradiative cell to produce electricity and. The alternative photovoltaic concept uses the earth as a heat source and the night sky as a heat sink and employs thermoradiative photovoltaics as well as concepts from the innovative field of radiative cooling.
The new discovery can transform a number of applications. For instance, thermoelectric devices can complement solar-powered lights in a region where changing batteries is difficult, as in the case of street lamps or far-off areas. The advanced versions of the anti-solar plates could be used to charge phones, light rooms, or power other electronics in low-resource or remote areas at night.
Further, advancements in anti-solar panels will produce carbon-free power for a number of applications. The efforts in the direction and the will to develop this alternative source of energy will determine the ultimate rollout of this new technology.
