Researchers have developed a new method for light and matter interaction, paving the way for the production of ultrathin silicon solar cells.
The University of California, Irvine (UC Irvine) team’s study is based on previous work related to the transformation of pure silicon from an indirect bandgap semiconductor to a direct bandgap one by altering its interaction with light.
They transformed light interactions with silicon by trapping photons, enhancing absorption by 10,000 times, and improving device performance without changing the material’s chemistry…
