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