摘要/Abstract

摘要： 本实验设计了一种简单有效的一体化大尺度染料敏化太阳能电池(DSC)模块, 开孔率(有效面积与总面积之比)高达85%, 远高于传统的串联和并联模块设计. 该设计采用在光阳极导电玻璃表面电镀镍栅极和对电极导电玻璃表面电镀镍薄膜修饰来降低电池传输电阻. 有效面积为510 mm2的电池模块光电转换效率η达到3.00%(AM 1.5, 100 mW/cm²), 填充因子(FF)为0.594, 与未镀镍的样品(η为0.537%, FF为0.251)相比, 性能显著提高. 并利用阻抗谱对大面积性能改善进行了解释, 还利用SEM、XRD等分析了电镀镍薄膜的质量.

Abstract: A new type of simple and monolithic large size dye-sensitized solar cell (DSC) module was designed with 85% aperture ratio (ratio of active area to total area), which was much higher than that of traditional series and parallel modules. The present module reduces the transfer resistance through the electroplated nickel grid on F-doped SnO₂ (FTO) of anode as well as the nickel film on the FTO of counter electrode. The nickel grid and film are inside the cell and the separation of the cell is not required, which is useful to reduce the block part of light and beneficial to improve the harvest of light energy. The photoelectric conversion efficiency (η) with the active area of 510 mm2 reaches 3.00% (AM 1.5, 100 mW/cm²) and the fill factor (FF) is 0.594, meanwhile the η and FF of DSC without nickel layer modification is only 0.537% and 0.251. So it is obvious that this novel designed module is very effective in the performance improvement. The underlying mechanism is understood based on the measurement of the electrochemical impedance spectroscopy (EIS) as well as the quality check of nickel film by scanning electron microscopy (SEM) and X-ray diffraction (XRD).

Key words: dye-sensitized solar cell, large area, module design, aperture ratio, electroplating nickel grid
