The key role of the gap plasmon mode on the plasmon metasurface “monolayer of Au@SiO2 nanoparticles / Al film” was proven for enhancing light absorption in a thin-film plasmon-perovskite solar cell in the near-IR range (1000-1200 nm), which is important for increasing the efficiency of photogeneration of charge carriers in the region of the maximum of the solar spectrum. 2. The sol-gel technology of the synthesis of thin TiO2 films was developed. The preparation of TiO2 films was performed by deposition the sol to various substrates by spin-coating followed by drying and calcination (thermal treatment) at 450°C. The proposed process allows obtaining TiO2 films of a required thickness for their use as an electron transport layer. 3. The electrical and optical characteristics of PEDOT:PSS films as a hole-transport layer were optimized, as well as the semiconductor interface was optimized. A new method was proposed, which includes multi-stage deposition of PEDOT:PSS films with intermediate washing with ethanol. This process provided a significant increase in the electrical conductivity of the PEDOT film by 2.2 times. The deposition of plasmon-active Au or Ag NPs at the interface of the heterojunction provided an increase in the overall efficiency by 20%, which confirms the important role of plasmon enhancement in increasing the efficiency of plasmonic solar cells. 4. The PL enhancement of a TiO2 film deposited on a substrate with Au nanoparticles was recorded, which is a consequence of the action of two mutually potentiating effects: (i) the interaction of TiO2 emitters with an intense surface plasmon field near Au NPs, (ii) charge transfer from Au NPs to TiO2.
