چکیده
We present a new approach to fabricate an integrated power pack by hybridizing energy harvest and storage processes. This power pack incorporates a series-wound dyesensitized solar cell (DSSC) and a lithium ion battery (LIB) on the same Ti foil that has double-sided TiO2 nanotube (NTs) arrays. The solar cell part is made of two different cosensitized tandem solar cells based on TiO2 nanorod arrays (NRs) and NTs, respectively, which provide an open-circuit voltage of 3.39 V and a short-circuit current density of 1.01 mA/cm. The power pack can be charged to about 3 V in about 8 min, and the discharge capacity is about 38.89 μAh under the discharge density of 100 μA. The total energy conversion and storage efficiency for this system is 0.82%. Such an integrated power pack could serve as a power source for mobile electronics.

High Efficient Transparent TiO2 Nanotube Dye-Sensitized Solar Cells: Adhesion of TiO2 Nanotube Membrane to FTO by Two Different Methods
In order to fabricate transparent TiO2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from Ti substrate by a re-anodization method. The membranes are transferred on FTO glass by two different methods. At the first one, 100mM Ti-isopropoxide is used to make TiO2 nanoparticles for adhering TiO2 nanotube membranes to FTO and ...

In this paper we selected two metal-free dyes (Dye 1 and Dye 2) based on 1,8-naphthalimide. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions. Spectrophotometric measurements of the organic dyes in DMF and on TiO2 substrate were carried out in order to assess changes in the status of the dyes. Maximum absorption wavelengths for Dye...
