Comparative performance of single and binary metal selenides in dye‑sensitized solar cells
Iron selenide (FeSe2), cobalt selenide (Co3Se4), and iron cobalt selenide (FeCo2Se4) have been synthesized via a two-step hydrothermal process. The formation of FeSe2, Co3Se4, and FeCo2Se4 has been proven by sample characterization to support their catalytic activity as the counter electrodes for dy...

| description | Iron selenide (FeSe2), cobalt selenide (Co3Se4), and iron cobalt selenide (FeCo2Se4) have been synthesized via a two-step hydrothermal process. The formation of FeSe2, Co3Se4, and FeCo2Se4 has been proven by sample characterization to support their catalytic activity as the counter electrodes for dye-sensitized solar cells (DSSCs). The poly(vinylidene fuoride-ohexafuoropropylene) (PVdF-HFP)/propylene carbonate (PC)/1,2-dimethoxyethane (DME)/1-methyl-3-propyl imidazolium iodide (MPII)/sodium iodide (NaI)/iodine (I2) gel electrolytes were assembled into DSSCs with FeCo2Se4, FeSe2, Co3Se4, or platinum (Pt) as the counter electrode. The DSSC with FeCo2Se4 counter electrode shows an efciency of 8.55%, whereas Pt counter electrode shows an efciency of 7.06%. The highest performance of DSSC achieved with FeCo2Se4 can be attributed to its highest surface area and pore volume. Hence, FeCo2Se4 can be used as a Pt-free counter electrode for highperformance DSSCs. |
