We describe recent progress in the synthesis of colloidal quantum dots (QDs) and describe their optoelectronic properties and further applications in solar technologies, including solar cells, solar-driven hydrogen production, and luminescent solar concentrators. QDs are fluorescent nanocrystals with nanoscale dimensions (<20 nm).
Controlling the synthesis and optoelectronic properties of colloidal QDs has emerged as a promising approach to improve the efficiency and stability of next-generation solar devices. Although recent QD research has led to significant advances in synthetic approaches and device efficiency, there are still several key challenges.
Solar cells based on solution-processed colloidal quantum dots are promising alternatives to conventional devices. This Review discusses recent advances and outstanding challenges for the field of quantum dot solar cells towards their commercialization.
One application field is photovoltaics where colloidal semiconductor nanocrystals are explored as components of photo-active layers which can be produced from liquid media, often in combination with conductive polymers.
