本研究主要探讨奈米科技最重要的产物之一量子点及其在太阳能电池技术上的应用。量子点太阳能电池是传统太阳能电池的一种有前途的替代品，在效率和制造成本方面比现有的太阳能电池具有许多优势。QD被认为是人造原子，并且可以衍生自周期表的不同族（例如II-VI或III-V）。因此，它们可以从几乎所有的金属和金属化合物中生产。量子点太阳能电池具有通过利用光生信使产生更大的光电压或更大的光电流来将太阳光子转换的最大可获得的热力学转换效率提高至高达约66%的潜力。概述了三种不同的量子点太阳能电池结构：（1）金属结太阳能电池、p-i-n结构太阳能电池和量子点敏化纳米晶（TiO 2）。
In this study, quantum dots (QDs) that are considered to be one of the most important products of nanotechnology, and their applications in the solar cell technology have been investigated. QD solar cells, a promising alternative to traditional solar cells, offer numerous advantages over existing ones in terms of efficiency and manufacturing costs. QDs are regarded as artificial atoms and can be derived from different groups of the periodic table (e.g. II-VI or III-V). Hence, they can be produced from almost all semiconducter and metal compunds. Quantum dot solar cell have the potential to raise the maximum obtainable thermodynamic transformation efficiency of solar photon transformation up to about 66% by utilizing photogenerated couriers to produce greater photo voltages or greater photo currents. Three different quantum dot solar cell structures are outlined: (1) metal semiconducter junction solar cell, p-i-n structure solar cell and quantum dot sensitized nanocrystalline (TiO2).
