A UK-Australian research group has built an intermediate band solar cell with a quantum ratchet semiconductor nanostructure that reportedly increases the ratchet band state lifetime of the device. Their new design builds on a cell structure known as the Vaquero-Stainer Device (VSD).An international research team has developed a new intermediate band solar cell (IBSC) design that includes a quantum ratchet (QR) semiconductor nanostructure. This new element reportedly enables storing photoelectrons in a long-lived state, thus enabling efficient optical re-absorption. Intermediate band solar cells ...Den vollständigen Artikel lesen ...
