Metallic quantum dots as sensitizers for solar cells

The concept of using the metallic quantum dots (MQD) as sensitizer in sensitized solar cells is presented. This concept is only possible due to the nano-scale size effects like emerging energy gap, states redistribution, and phonon bottleneck. Also, the initial work to grow silver quantum dots on ZnO film by sputtering and then post annealing is presented and discussed. This growth procedure will be used later to realize the concept device.
