I am trying to fabricate a fiber shape TiO2 nanowire-based dye-sensitized solar cell on Ti wire. I use a hydrothermal route to grow the TiO2 nanowires. Then I absorb the nanowires with N719 dye. I use a platinum wire as the counter electrode and an iodine-based electrolyte to complete the connection. But when I make the connection with the potentiostat and take the cyclic voltammetry I do not get the required I-V plot. Rather I get something like the one in the attached file. Can anyone please help with this issue?
Did you shine light on your TiO2 specimen? Did you check crystallinity and conductivity of your TiO2?
Hi Brishty,
it is hard to suggest without knowing the configuration of your fiber based solar cell. I'm afraid that your cell is short-circuited if your Ti fibers is in contact with the pt wire-CE.
Also, you need to illuminate your cells to get the I-V curve of working cells. You can measure the current response using lsv technique in two-electrode system (WE and Ref-CE).
Krishnan Raja Yes, I shone a simulated 1.5G illumination. I followed the synthesis procedure of this journal.
