Abstract
The progresses of colloidal quantum dots (CQDs) in the last decade have brought many developments in related optoelectronic devices. Genuine CQD optoelectronic devices, however, still suffer from low efficiency and short life span, which seriously hinder their practical use. A novel integration scheme is proposed and demonstrated to alleviate these problems. By combination of regular semiconductor devices and CQD thin film layers, we can achieve a much better performance and avoid the lifetime issue. The CQD layer can be applied in both photovoltaic reaction and general illumination via its strong absorption and emission characteristics. The design principles, fabrication technology, and device analysis will be discussed in detail.
