A silver-based organic salt, silver bis(trifluoromethane-sulfonyl)imide (AgTFSI), was employed as an effective p-type dopant for the triarylamine-based organic hole-transport material Spiro-MeOTAD, which has been successfully applied in solid-state dye-sensitized solar cells (ssDSCs) and perovskite solar cells (PSCs). The power conversion efficiencies (PCEs) of AgTFSI-doped devices improved by 20%, as compared to the device based on the commonly used oxygen doping both for ssDSCs and PSCs. Moreover, the solid-state dye-sensitized devices exposed to AgTFSI as dopant showed considerably better stability than those of oxygen doped, qualifying this p-type dopant as a promising alterative for the preparation of highly efficient as well as stable ssDSCs and PSCs for the future.
一种银基有机盐，双（三氟甲磺酰）亚胺银（AgTFSI），被用作基于三芳基胺的有机空穴传输材料Spiro-MeOTAD的有效p型掺杂剂，该材料已成功应用于固态染料敏化太阳能电池（ssDSC）和钙钛矿太阳能电池（PSC）。与基于常用氧掺杂的器件相比，AgTFSI掺杂器件的功率转换效率（PCE）提高了20%，无论是对于ssDSC还是PSC。此外，以AgTFSI作为掺杂剂的固态染料敏化器件显示出比氧掺杂器件更好的稳定性，这使这种p型掺杂剂成为未来制备高效且稳定的ssDSC和PSC的有前途的替代品。
