摘要： In one aspect of the invention, a dye sensitized solar cell has a counter-electrode including carbon-titania nanocomposite thin films made by forming a carbon-based ink; forming a titania (TiO2) solution; blade-coating a mechanical mixture of the carbon-based ink and the titania solution onto a substrate; and annealing the blade-coated substrate at a first temperature for a first period of time to obtain the carbon-based titania nanocomposite thin films. In certain embodiments, the carbon-based titania nanocomposite thin films may include solvent-exfoliated graphene titania (SEG-TiO2) nanocomposite thin films, or single walled carbon nanotube titania (SWCNT-TiO2) nanocomposite thin films.

摘要： Disclosed is a photovoltaic-electrochromic-battery all-in-one device in which the functions of a dye-sensitized solar cell, an electrochromic device, and a lithium secondary battery are fused into one device. The all-in-one device according to the disclosure includes a photoelectrode uses as an active layer of a dye-sensitized solar cell (DSSC), a counter electrode used as an electrochromic layer opposite to the photoelectrode, and an electrolyte containing a lithium salt. The all-in-one device according to the disclosure allows the function of the DSSC that generates electrons by receiving solar energy, the function of an electrochromic device (ECD) that blocks light by discoloring an electrode with generated electrons, and the function of a lithium secondary battery (LIB) that stores generated electrons and uses the stored electrons again to be all implemented by one device.
