Energy materials: core/shell structural photoelectrodes assembled with quantum dots for solar cells

Narrow-band-gap semiconductor quantum dots (QDs) are considered as next-generation sensitizers for solar cells because of their extraordinary optical and electrical properties in terms of tuneable band gap, high molar extinction coefficient, and large intrinsic dipole moment, which may facilitate charge separation in solar cells. Moreover, theoretical photovoltaic conversion efficiency of QDs-sensitized solar cells can reach up to 44% in view of multiple exciton generation (MEG).(Published: 11 June 2013)Citation: Nano Reviews 2013, 4: 21080 - http://dx.doi.org/10.3402/nano.v4i0.21080
