Photon Recycling

Photon recycling is a process in advanced solar cells where emitted photons—light particles released during electron movement—are reabsorbed within the cell to generate new charge carriers. This internal recycling of photons effectively boosts the efficiency of the solar cell by reducing energy losses that would otherwise occur when photons escape. Think of it as an internal mirror system that reuses the light energy, enabling the solar cell to convert more sunlight into electricity. This technique is especially useful in high-performance photovoltaic devices, leading to higher power output without requiring additional external light input.
