Most single-layer silicon solar cells, due to their ability to use only a particular wavelength of light in the sun, have an efficiency limit of approximately 32% absorption and conversion from radiation, which is known as the "Hicks-Quiets limit."
The MIT research team recently published a new solar thermophotovoltaic device (STPV) in the journal Nature Energy that dramatically improves energy conversion rates and reduces waste heat from power generation.
Traditional solar cells can only convert certain wavelengths of sunlight in the sunlight into electricity and can not use the same portion of the heat at the same time and have watched them dissipate in the environment.
The MIT research team's new solar cells contain an extra layer of nanotube nanotube structure made of nanophotonic crystal that absorbs both light and heat and converts it to light of a particular wavelength. These are precisely adjusted by the light, and then by the photovoltaic cells into electricity, effectively improve power generation efficiency.
In theory, this new technology can double the amount of electricity generated by a given block of solar panels, but due to the manufacturing difficulties of carbon nanotubes and their inability to rapidly spread within a few years, the team found the results to be significant: This is the latest record of what we know about solar thermal photovoltaics, and there is a good chance of being actually used in the industry.
