CdS nanoflake arrays for highly efficient light trapping

Abstract

CdS nanoflake arrays (NFAs) exhibit unprecedented light absorption capability, and they can serve as a scaffold to load thin organic absorbers for extraordinarily high light absorption. As a result, the hybrid solar cell consisting of NFAs and organic absorber yields a ten-times high short-circuit photocurrent compared to the counterpart device with a common planar structure.
