In accordance with embodiments of the present disclosure, a catalyst layer for electrolyte based tri-iodide/iodine redox couples of a dye- sensitized solar cell (DSSC) includes carbon nanotubes and cement, such as a conventional type of cement suitable for use as an infrastructure construction or building material. Representative example catalyst layers were prepared by mixing carbon nanotube powders with cement powder as a binder, and such catalyst layers were coated on a transparent conducting oxide (TCO) glass substrate using a painting technique without heating. By mixing carbon nanotubes and cement at different carbon nanotube to cement weight percentage ratios, i.e., 17:83, 29:71, 38:62, 44:56 and 50:50, to establish an appropriate cement fraction, catalyst layers with low electrical resistivity, high electro-catalytic activity, and excellent photoelectric conversion efficiency have been fabricated, where the photoelectric conversion efficiency has been measured as 85.56% of that of a DSSC having a conventional platinum catalyst based counter electrode. |
