    Abstract Image

    Over the past decades, the synthetic chemistry of colloidal semiconductor nanocrystals (or quantum dots, QDs) has advanced rapidly, which offers a low-cost route for developing solar cells with QDs as the active materials. Solution-processed QD-based solar cells may simultaneously satisfy needs for low cost and high efficiency, yet a long lifetime. This article shall analyze three main types of QD-based solar cells including their specific design principle, brief history, and key breakthroughs. Though each type of QD-based solar cell is largely different from the others in its specific device design, there is a unique feature for all QD-based solar cells. When a QD absorbs a photon with energy greater than its optical bandgap, a bonded exciton─an electron–hole pair bonded by electrostatic interaction─is generated, instead of free carriers in their bulk counterparts. This article shall discuss the elementary steps involved in these exciton-centered devices.
