采用DSC、硅（Si）和砷化镓（GaAs）等不同底层器件制备了机械堆叠的单照明区顺序串联多结染料敏化太阳能电池（ssm -DSC）。利用近红外（>750纳米）光子转化为电能，对这三种技术中的每一种进行了探索。使用这些光子对多结器件功率转换效率的影响通过三亚单元SSM-DSC设计进行了研究，其中顶部和中间亚单元分别是带有d35和b11敏化剂的DSC器件。功率转换效率依次为：DSC/DSC/GaAs>DSC/DSC/DSC>DSC/DSC/Si。作为独立的太阳能电池，研究了第三个子电池技术的低光条件，以了解作为多结系统的一部分接收低光强度的影响。在这些研究中，GaAs和DSC作为底部器件在过滤或减少照明下都表现出优于Si的响应。研究了恶劣温度对DSC器件性能的影响。
Mechanically stacked single illuminated area sequential series multijunction dye-sensitized solar cells (SSM-DSCs) were fabricated with varying bottom devices including DSC, silicon (Si), and gallium arsenide (GaAs). The use of near-infrared (>750 nm) photons for conversion into electricity is probed for each of the three technologies. The effect of using these photons on multijunction device power conversion efficiencies is investigated with a three-subcell SSM-DSC design where the top and middle subcells were DSC devices withD35andB11sensitizers, respectively. The power conversion efficiencies were found to follow the order:DSC/DSC/GaAs>DSC/DSC/DSC>DSC/DSC/Si. Low-light conditions were examined for the third subcell technologies as independent solar cells to understand the effects of receiving low light intensity as part of a multijunction system. GaAs and DSC as bottom devices both demonstrated a superior response under filtered or reduced illumination to that of Si in these studies. The influence of harsh temperatures on DSC device performance was also examined.
