DESIGNANO - The Aesthetics of Imperceptibility - paper research invited by Tincuta Heinzel

Description

This collaboration was initiated by Tincuta Heinzel, under the frame of the project DESIGNANO - The Aesthetics of Imperceptibility. The project is coordinated by Tincuta Heinzel, who is resident at IMERA, Marseille, France in 2021. Tincuta Heinzel undertakes to run the Project in cooperation with IMERA and in collaboration with 2580 Association. I will document the result here, the tasks are listed below:

  1. Writing a description of the experiments with DIY nanotechnologies;
  2. Supporting the production of any publications resulting from the project;
  3. Participate in an interview with researchers from Aix-Marseille University.

Technical Questions to Expert of Photovoltaic

Few questions listed below will be forwarded to the experts from IMERA. Mainly all questions are around "how to produce the TiO2 layer in low temperature?"

  1. How to manufacture sustainable, flexible, low resistance electrolyte in solid form for FDSC (flexible dye sensitized solar cell)? for example, in the paper Ultra-Thin TiO2 Layers for Enhancing the Conversion Efficiency of Flexible Dye-Sensitized Solar Cells it mentioned: The electrolyte consisted of 0.41M LiI, 0.5 M 4-tert-butylpyridine, 0.05 M I2, and 0.6M 1,2-dimethyl-3-n-propylimidazolium iodide in 3-methoxypropionitrile (MPN). Can you explain what is it?
  2. How to produce TiO2 electrode on glass or PET substrate with low temperature without high technology such as CVD or RF sputter deposition?
  3. The other interesting direction is related to biomineralization: How to "sinter" TiO2 in low temperature by the help of
  4. How to sinter the TiO2 layer by SLS (Selective Laser Sintering) with 1064nm laser? The suggested parameter including defocusing distant, laser wavelength, laser dot diameter are indicated in the paper "Laser Sintering of TiO2 Films for Flexible Dye-Sensitized Solar Cells" and the other paper Selective laser sintering of TiO2 nanoparticle film on plastic conductive substrate for highly efficient flexible dye-sensitized solar cell application†.
  5. Can you list few example of existing solar textile projects?

Current Prototypes

  1. I am now able to create DSSC size up to 30x60cm at home with P25 TiO2 powder, however the current is very low due to the internal resistance of the FTO glass.
  2. Several nature dyes were tested to create colorful DSSCs, however the color fades under sunlight.
  3. I have tried to create graphical carbon electrode with screen print.
  4. I have tried to create flexible TiO2 layer by EMF tape transferring, it worked a little bit but the result was unclear without proper measuring skill.
  5. I have tried to grow kombucha with dyed TiO2 powders, a solid membrane was formed, but the result was unclear without proper measuring skill.
  6. I have tried to make solid electrolyte layer with gelatin, only voltage was measured, the current was measured zero because of the high resistance of gelatin.
  7. I have tried with the papain method once to produce thin TiO2 layer on glass, but didn't have equipment or skill to testify the result.
