  4. 2. The Study of II-VI Semiconductor Nanocrystals Sensitized Solar Cells

    Author : Chunze Yuan; Ying Fu; Lars Kloo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; quantum rods; nanocrytals; solar cells; colloidal; type-II; electron injection; organic electrolyte.;

    Abstract : Semiconductor nanocrystals, also referred to as quantum dots (QDs), have been the focus of great scientific and technological efforts in solar cells, as a result of their advantages of low-cost, photostability, high molar extinction coefficients and size-dependent optical properties. Due to the multi-electron generation effect, the theoretically maximum efficiency of quantum dots-sensitized solar cells (QDSCs) is as high as 44%, which is much higher than that of dye-sensitized solar cells (DSCs).
