| Research Abstract |
We proposed the quantum-dot-type solar cell, in which polymer/molecular wires with designated molecular arrangements grown by Molecular Layer Deposition(MLD) are used for the sensitizing layer, and demonstrated the proof-of-concept. The following results are obtained.
1) Polymer quantum dots, in which different-length quantum dots are involved, were constructed by MLD.
2) Polymer wires were grown on semiconductor layer surfaces, and their sensitizing effect was observed. This suggests the potentiality of the polymer quantum dots as the sensitizing layers.
3) By MLD, multi-molecule-stacked structures consisting of p-type dyes and n-type dyes were grown on ZnO surfaces. Widening of the wavelength regions for light absorption and sensitization was observed. This suggests the potentiality of the multi-dye sensitization.
