Indoor solar panels are particularly appealing for use in small devices. For some applications, powering devices from artificial light sources removes the need for batteries, making IPV-powered devices a more sustainable alternative.
Indoor PV is often controllable and more predictable than solar irradiation, and so the energy usage and capacity can be reliably anticipated. Therefore, this abundant and reliable light source means the opportunities for indoor devices to be powered by photovoltaics are vast.
Indoor solar is somewhat of an oxymoron. How can a solar panel work without sunlight? Solar panels, or Photovoltaics (PV), work via the photoelectric effect, which converts light into electricity.
Therefore, outdoor photovoltaics are not appropriate for indoor applications. This change in light source and spectrum has a detrimental impact on the performance of traditional outdoor solar panels when used indoors. You need to test outdoor solar cells under light that mimics solar irradiance. This is usually the AM1.5 standard spectrum.
Indoor photovoltaics (IPV) - sometimes known as indoor solar panels - may seem like a contradictory statement, but this technology shows great potential across many industries. IPV consists of conventional photovoltaic technology but instead of using sunlight to promote conductivity, they use energy from artificial light sources.
