Abstract

Carbon microspheres (CSs) were successfully fabricated and used as counter electrodes of dye-sensitized solar cells (DSSCs). CSs were obtained through a fast microwave-assisted approach using sucrose as the precursor in a microwave system and subsequent thermal treatment at 600, 800 and 1000°C. A maximum photovoltaic conversion efficiency of 5.5% is achieved for DSSCs based on the CSs counter electrodes, which is comparable to the cell based on conventional Pt counter electrode at one sun (AM 1.5 G, 100 mW cm(-2)). The results suggest the CSs to be a potential candidate for counter electrodes of DSSCs.

摘要

成功制备了碳微球（CSs）并将其用作染料敏化太阳能电池（DSSC）的对电极。通过在微波系统中使用蔗糖作为前驱体的快速微波辅助方法以及随后在600、800和1000°C下进行热处理来获得CSs。基于CSs对电极的DSSC实现了5.5%的最大光电转换效率，这与基于传统Pt对电极的电池在一个太阳（AM 1.5 G，100 mW cm(-2)）下的效率相当。结果表明CSs是DSSC对电极的潜在候选材料。
