Peafowl Plasmonics light harvesting
There are many different kinds of solar cells on the market – silicon cells are the most well-known, but there are also organic solar cells, thin-film solar cells (e.g CIGS, CdTe), perovskite solar cells etc.
Yet, our technology differs from all other solar cell technologies in a fundamental way.
The core of our technology – the process for how light is converted to electricity – is different. In other technologies, the mechanism is based on that when a photon is absorbed by the active material, a certain amount of energy is used up to excite an electron from an electronic level to an empty level, and that electron becomes one of the electrons in the electricity current that the cell generates. For a given material, a specific amount of energy is needed to excite (“kick out”) an electron. If the photon has less energy than needed, no electron will be excited by it. If the photon has excess energy compared to what is needed, the excess will be wasted as heat.
