Researchers enhanced light-matter interaction in silicon, boosting solar cell efficiency and enabling new energy applications.
Researchers have developed a new method for light and matter interaction, paving the way for the production of ultrathin silicon solar cell s.
The team highlights that the discovery may contribute to the expansion of energy-converting technology into a wide range of uses, such as onboard car and device charging and thermoelectric apparel.In the new study, researchers used a new method that involved changing the light instead of the material.
As an indirect bandgap semiconductor, silicon’s limited optical properties hinder advancements in solar energy conversion and optoelectronics. This is a significant drawback, given that silicon is the second-most abundant element in Earth’s crust and serves as the foundation for the global computer and electronics industries.
“Figuratively speaking, we can ‘tilt the textbook,’ as these photons enable diagonal transitions. This dramatically impacts a material’s ability to absorb or emit light,” said Ara Apkarian, distinguished professor emeritus of chemistry at UC Irvine and co-author of the study.
