Molecular assembling and quantum dot formation in polymers by MLD and their applications to waveguide-type solar cells and optical switches

我们提出了以分子层沉积(MLD)生长的具有特定分子排列的聚合物/分子线作为敏化层的量子点型太阳能电池，并进行了概念验证。研究结果如下：1)用MLD法制备了不同长度的聚合物量子点；2)在半导体层表面生长了聚合物线，观察了聚合物线的敏化效果。3)利用分子激光二极管在氧化锌表面生长了由p型染料和n型染料组成的多分子堆积结构。观察到光吸收和增感的波长范围变宽。这表明了多染料敏化的潜力。

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.
