PSC with 1.5 wt%PVP/0.5 wt%PVA kept 82.2% of its initial PCE after 30 days in air. Interaction between PVP/PVA and perovskite improves film quality and stability. Synergistic effect between PVP/PVA and perovskite improves cell performance.
PVA is a flexible, transparent, non-toxic, non-hazardous, and biocompatible substrate. The new PV depends on a selective light-absorption layer to reach high power conversion energy. These kinds of solar cells have sufficient efficiency. At the same time, selective material is very important to simulate development and market requirements.
As researchers continue to investigate new materials and techniques for solar cell fabrication [14, 15, 16, 17, 18, 19], PVA can help increase the stability and lifetime of dye- sensitized solar cells. An efficient field-effect passivation was designed through multiple layers, the first being the protective PVA layer.
Such synergistic effect of complexation and hydrogen bonds after adding PVP/PVA can not only passivate the defects of perovskite, but also enhance the stability of perovskite crystal structure, thus improving the efficiency and stability of solar cells. Fig. 11.
Meanwhile, the peak of PVA/modified glass fiber composites in the 2θ range of 17–20° increased with the different modified glass fibers added. These observations could be found because of the different hydrogen bonding interactions formed between PVA and the modified glass fibers, and showed an increased difference in the crystallinity of PVA .
Furthermore, compared with pure PVA, the crystallinity and grain size of the composites increased, indicating that the tensile process and the orderly arrangement of glass fibers synergistically induced the further growth of PVA grains. And the introduction of glass fibers further promoted the crystallization process of PVA. Fig. 7.
