Five Covalent Organic Frameworks (COFs) were synthesized and applied to Dye-Sensitized Solar Cells (DSSCs) as dyes and additives. These porous nanomaterials are based on cheap, abundant commercially available ionic dyes (thionin acetate RIO-43, Bismarck brown Y RIO-55 and pararosaniline hydrochloride RIO-70), and antibiotics (dapsone RIO-60) are used as building blocks. The reticular innovative organic framework RIO-60 is the most promising dye for DSSCs. It possesses a short-circuit current density (J) of 1.00 mA/cm, an open-circuit voltage (V) of 329 mV, a fill factor (FF) of 0.59, and a cell efficiency (η) of 0.19%. These values are higher than those previously reported for COFs in similar devices. This first approach using the RIO family provides a good perspective on its application in DSSCs as a dye or photoanode dye enhancer, helping to increase the cell's lifespan.
合成了五种共价有机框架（COF）并将其作为染料和添加剂应用于染料敏化太阳能电池（DSSC）。这些多孔纳米材料基于廉价、丰富的市售离子染料（硫堇醋酸盐RIO - 43、俾斯麦棕Y RIO - 55和盐酸副玫瑰苯胺RIO - 70），并使用抗生素（氨苯砜RIO - 60）作为构建单元。网状创新有机框架RIO - 60是用于DSSC最有前景的染料。它具有1.00 mA/cm的短路电流密度（J）、329 mV的开路电压（V）、0.59的填充因子（FF）以及0.19%的电池效率（η）。这些值高于之前在类似器件中报道的COF的值。这种使用RIO家族的首次方法为其作为染料或光阳极染料增强剂在DSSC中的应用提供了良好的前景，有助于延长电池的寿命。
