Abstract

Dye-sensitized photovoltaic wires (DSPVWs) are developed using anodized Ti wires that contain ordered arrays of TiO2 nanotubes. The prototype DSPVW consists of N719 dye-adsorbed TiO2 nanotube arrays around a Ti wire as a working electrode, a platinum wire as a counter electrode, and an organic electrolyte encased in a capillary glass tube. The effect of length of nanotube arrays on the photovoltaic performance of DSPVWs is studied systematically. A solar-to-electric conversion efficiency of 2.78% is achieved with 55 microm long nanotubes under 98.3 mW/cm(2) AM 1.5 simulated full light. The prototype device is capable of achieving a long distance transport of photocurrent and harvesting all light from any direction in surroundings to generate electricity.

摘要

染料敏化光伏线（DSPVW）是使用含有有序 TiO2 纳米管阵列的阳极氧化 Ti 线开发的。原型 DSPVW 由 N719 染料吸附的 TiO2 纳米管阵列围绕作为工作电极的 Ti 线、作为对电极的铂丝以及封装在毛细管玻璃管中的有机电解质组成。研究了纳米管阵列长度对 DSPVW 光伏性能的影响。在 98.3 mW/cm² AM 1.5 模拟全光下，使用 55 µm 长的纳米管实现了 2.78%的太阳能到电能的转换效率。原型器件能够实现光电流的长距离传输，并从周围任何方向收集所有光线以发电。
