为了解决由背接触型硅底电池组成的三端串联太阳电池，原则上对光谱变化具有容忍性，我们制作了利用导电金属纳米颗粒阵列键合的三端GaAs/Si串联器件，并测量了功率提取。即使在不同的光谱条件下，也能提取相当于顶子电池和底子电池产生的功率总和的功率，这表明具有背接触型底部电池的三端串联太阳能电池在地面应用中的优势。
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.
