To address three-terminal tandem solar cells composed of a back-contact-type Si bottom cell, which, in principle, has a tolerance against spectral variation, we fabricate the three-terminal GaAs/Si tandem device bonded using conductive metal nanoparticle arrays and measure the power extraction. A power equivalent to the sum of the power generated by the top and bottom subcells is extracted even under varying spectral conditions, which indicates advantages in three-terminal tandem solar cells with a back-contact-type bottom cell for terrestrial applications.

具有使用导电金属纳米粒子阵列键合的背接触式底部电池的三端串联太阳能电池

为了解决由背接触型 Si 底部电池组成的三端串联太阳能电池,原则上,该电池对光谱变化具有耐受性,我们制造了使用导电金属纳米颗粒阵列键合的三端 GaAs/Si 串联器件和测量功率提取。即使在不同的光谱条件下,也能提取与顶部和底部子电池产生的功率总和相等的功率,这表明具有背接触式底部电池的三端串联太阳能电池在地面应用中的优势。
