Title: “Development of photoelectrochromic devices powered by economical dye-sensitized solar cells”

    IRN АР09259604

    Research object:  dye-sensitized solar cells.

    Overall goal: to develop photoelectrochromic devices operating on inexpensive dye-sensitized solar cells.

    Practical significance: obtaining a photoelectrochromic device operating on inexpensive dye-sensitized solar cells.

    Expected results:

- Publication of articles;

- Novel low-cost Pt-free counter electrodes for dye-sensitized solar cells will be developed;

- Novel economical porphyrin sensitizers for dye-sensitized solar cells will be prepared;

- Novel electrochromic materials will be synthesized;

- Low-cost photoelectrochromic device will be fabricated;

- The development of photoelectrochromic devices addresses both ecological and energy problems and paves way to many smart and sustainable products like smart windows, displays, smart thermal control coatings, auto-dimming mirrors, electronic papers and anti-reflection coatings. These products would be a great impact to the evolution of living standards and economical growth of Kazakhstan enhancing country’s competitiveness and creating new jobs.

   Results obtained in 2021:

- A literature review was done. A review article on the topic "Platinum-free counter electrodes based on transition metal chalcogenides for dye-sensitized solar cells" is being prepared.

- Platinum-free counter electrodes based on transition metal sulfides were prepared and their characteristics were obtained.

- synthesized were the precursors for the preparation of porphyrin dyes without long alkyl chains and ligands that bind dyes.

- dye-sensitized solar cells were assembled on the basis of synthesized counter electrodes and their photoelectric measurements were carried out. As a result, the Cu-Ni-S counter electrodes showed higher efficiency than platinum.
