【摘要】：采用磁控溅射系统在晶硅太阳能电池表面沉积了不同覆盖率的Cu纳米颗粒。以没有纳米颗粒覆盖的太阳能电池作为参考电池,研究了Cu纳米颗粒对太阳能电池电学特性的影响。结果表明:在覆盖率增加的过程中,纳米颗粒主要以单个纳米颗粒的形式出现,并且很少有纳米颗粒发生团聚现象。具有2%纳米颗粒覆盖率电池的外量子效率最好。电流-电压特性测量结果表明:具有2%纳米颗粒覆盖率电池的填充因子和转换效率最好。与参考电池相比,2%纳米颗粒覆盖率电池的填充因子相对提高了36.5%,转换效率相对提高了37%。
[Abstract]:The Cu nanoparticles with different coverage were deposited on the surface of silicon solar cells by magnetron sputtering system, and the solar cells without nano-particles were used as reference cells. The effect of Cu nanoparticles on the electrical properties of solar cells was studied. The results showed that the nanoparticles mainly appeared in the form of single nanoparticles in the process of increasing coverage. The external quantum efficiency of the battery with 2% nanocrystalline coverage is the best. The measurement results of current-voltage characteristics show that:. The filling factor and conversion efficiency of the battery with 2% nanocrystalline coverage are the best compared with the reference battery. The filling factor and conversion efficiency of 2% nanocrystalline coverage battery increased by 36.5 and 37 respectively.
