Solar indoor power supply system

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.

Photovoltaics used outdoors are chosen to fit the solar spectrum. However, indoors the incident photons are from an artificial light source, with a different spectrum. Therefore, outdoor photovoltaics are not appropriate for indoor applications.

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 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.

Successful adoption of indoor photovoltaics alleviates the need for disposable batteries. This promotes a more sustainable approach to personal electronic devices. Buildings now have the opportunity to use a two-tiered sustainable energy approach, where both the mains and wireless devices are operated more sustainably.
