[资源] 【Nature Chemistry】基于卟啉敏的染料敏化太阳能电池将光电转换效率提高到了13%！

染料敏化太阳能电池最高效率停留在12.3%很久后，终于有所突破了。看着钙钛矿太阳能电池效率不断的增长，着实为DSSC担忧。

【Nature Chemistry】Dye-sensitized solar cells with 13% efficiency achieved through the molecular engineering of porphyrin sensitizers

Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of
fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered
porphyrin dye, coded SM315, which features the prototypical structure of a donor–p-bridge–acceptor and both maximizes
electrolyte compatibility and improves light-harvesting properties. Linear-response, time-dependent density functional
theory was used to investigate the perturbations in the electronic structure that lead to improved light harvesting. Using
SM315 with the cobalt(II/III) redox shuttle resulted in dye-sensitized solar cells that exhibit a high open-circuit voltage VOC
of 0.91 V, short-circuit current density JSC of 18.1 mA cm–2, fill factor of 0.78 and a power conversion efficiency of 13%.
