摘要

目前使用的多晶材料的晶粒通常在一毫米或更多的数量级。本文研究了不同材料(Eurosolare材料和Sumitomo six的EMC材料)的改进。所使用的氢化方法包括在rf等离子体中进行氢化。从基材的正面或背面进行处理。通过AM1.5照明下的I-V测量、暗I-V测量和微波探测光导衰减法提取少数载流子寿命来说明加氢的有益作用。对整个太阳能电池的测量只显示了氢化的宏观结果,因此也就集中了结果。从对小型台面型二极管的测量中获得了更多的见解。通过这种方法,我们可以区分晶界贯穿有源器件的二极管和完全包含在一个晶界内的器件。这允许人们分离氢化对晶界和晶内缺陷的影响。采用暗i - v测量和深能级瞬态光谱(DLTS)来表征Eurosolare材料中的二极管。dlt -光谱显示二极管有一个宽的晶界带穿过它们。在正面直接接受h等离子体处理的样品上,这个峰完全消失。

A study on the microscopical and macroscopical effects of hydrogenation on the performance of multicrystalline solar cells
The grains in the multicrystalline materials used nowadays are typically in the order of a mm or more. In the present study the improvement of different materials (Eurosolare material and EMC material from Sumitomo Sitix) is studied. The method of hydrogenation used consists of a hydrogenation in an RF-plasma. The treatment is from the front or back side of the substrate. The beneficial effect of hydrogenation is illustrated by I-V-measurements under AM1.5 illumination, dark I-V measurements and extraction of minority carrier lifetime by the microwave-detected photoconductive decay method. The measurement on the full solar cell reveals only macroscopic and hence lumped consequences of the hydrogenation. Additional insight was gained from measurements on small mesa-type diodes. In this way we can discriminate between diodes with a grain boundary running through the active device and devices fully contained within one grain. This allows one to split the effects of the hydrogenation on the grain boundaries and the intra-grain defects. Dark I-V-measurements and deep-level transient spectroscopy (DLTS) were used to characterize the diodes in the Eurosolare material. The DLTS-spectra revealed a broad band for the diodes with a grain boundary running through them. This peak completely disappeared on samples which received a direct H-plasma treatment from the front side.
