We report on the structural characterization and the photovoltaic performances of novel photoelectric conversion materials fabricated by simplified and cheap procedures based on a chemical approach. Our prepared composite microparticles were composed of fluorosilicate/phosphorus oxide holding together by ammonium. When such composite microparticles were used in the active layer of the hybrid solar cells, the relatively high Jsc was obtained by causing the adequate carrier transport from the active layer to each electrode, attaining the best photovoltaic performance with a PCE of 4.45 %. These findings indicate that the fluorosilicate/phosphorus oxide composite microparticles have sufficient ability as the photoelectric conversion materials.

The sun provides a plentiful and inexpensive source of carbon-neutral energy that has yet to be fully utilized. This is a major driving force behind the development of organic photovoltaic (OPV) materials and devices, which are expected to offer benefits such as low cost, flexibility, and widespread availability. For the photovoltaic performance enhancement of the inverted ZnO-nanorods (NR)/organic hybrid solar cells with poly(3-exylthiophene):(6,6)-phenyl-C61-butyric-acid-methylester (P3HT:PCBM) and poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) active layers, gold nanoparticles (Au-NPs) were introduced into the interface between indium-thin-oxide cathode layer and ZnO cathode buffer layer, and the efficiency improvement was observed. It's worth noting that adding Au NPs had both a positive and negative impact on device performance. Au NPs were shown to be advantageous to localized surface plasmon resonance (LSPs) in the coupling of dispersed light from ZnO NRs in order to extend the light's path length in the absorbing medium. Although the light absorption in the active layer could be enhanced, Au NPs might also act as recombination centers within the active layer. To avoid this adverse effect, Au NPs are covered by the ZnO seeded layer to prevent Au NPs from direct contact with the active layer. The dominant surface plasmonic effect of Au NPs increased the photoelectric conversion efficiency from 2.4% to 3.8%.

A multilayer TiO2 film featured with gradual scattering structure was developed and used as photoelectrode for dye-sensitized solar cells. This structure of film consists of P25 nanoparticles and TiO2 aggregate which was synthesized by micro-emulsion method as scattering centers The scattering centers were deposited by gradually increasing the amount from the film’s bottom to its top. The special films were used for the studies on the photovoltaic performance of N719 and Zn-3, and their photoelectric conversion efficiencies were 7.34% and 4.04%, respectively. Furthermore, more improvement of the conversion efficiency is realized for Zn-3 than for N719 by using our newly developed multilayer films as photoelectrode compared with ordinary photoelectrode.

Perovskite Layer

The hole transport layer (HTL) is one of the main factors affecting the efficiency and stability of perovskite solar cells (PSCs). However, obtaining HTLs with the desired properties through current preparation techniques remains a challenge. In the present study, we propose a new method which can be used to achieve a double-layer HTL, by inserting a CuI layer between the perovskite layer and Spiro-OMeTAD layer via a solution spin coating process. The CuI layer deposited on the surface of the perovskite film directly covers the rough perovskite surface, covering the surface defects of the perovskite, while a layer of CuI film avoids the defects caused by Spiro-OMetad pinholes. The double-layer HTLs improve roughness and reduce charge recombination of the Spiro-OMeTAD layer, thereby resulting in superior hole extraction capabilities and faster hole mobility. The CuI/Spiro-OMeTAD double-layer HTLs-based devices were prepared in N2 gloveboxes and obtained an optimized PCE (photoelectric conversion efficiency) of 17.44%. Furthermore, their stability was improved due to the barrier effect of the inorganic CuI layer on the entry of air and moisture into the perovskite layer. The results demonstrate that another deposited CuI film is a promising method for realizing high-performance and air-stable PSCs.
