碲化銦奈米粒子的合成、特性鑑定及在太陽能電池的應用

Abstract

本論文中探討碲化銦奈米粒子的合成與特性上的鑑定，以及應用於量子點敏化太陽能電池上的影響。在本文中我們使用一方法來製備碲化銦半導體奈米粒子，並且利用浸泡的方式滲入作為太陽能電池陽極的二氧化鈦奈米粒子薄膜□，配合碘溶液作為氧化還原的電解質，以及由核能研究所提供的鉑電極作為陰極，封裝成一太陽能電池元件並測量其光電流與光電壓。陽極的二氧化鈦奈米粒子薄膜是利用膠體溶液法合成的，並藉由塗佈棒塗佈在FTO導電玻璃上。經過鍛燒之後，會形成粒子大小約在20~50奈米之間的二氧化鈦薄膜。碲化銦奈米粒子經過許多實驗探討及特性鑑定，在最佳化的實驗參數下參雜於二氧化鈦薄膜裡。在實驗結果中，我們可以看到覆蓋最佳化的碲化銦奈米粒子後其光電壓與效率的增加。

In this research, Indium telluride(InTe) nsnoparticles were synthesized by wed chemistry method, The as-synthesized InTe nanoparticles was used to fabricate Quantum Dot Sensitized Solar Cell(QDSSC). TiO2 thin film covered with InTe nanoparticle was used as the anode, the I3-/I- was used as the electrolyte, and the platinum electrode provided by INER was used as the cathode to assemble a solar cell device for photocurrent and photovoltage measurements. TiO2 nanoparticle film was synthesized by the Sol-gel method, and printed on FTO glass by doctor blade. After calcinations the average particle size of TiO2 particle is approximately within 20~50 nm. The effect of InTe particle size to the photocurrent and energy conversion efficiency were studied. According to the experimental result, the InTe covered on TiO2 thin film exhibits an enhancement in its I-V photocurrent.
