Solution stability of active materials for organic photovoltaics

Photoelectrochemistry of Poly‐3‐hexylthiophene and Stannum Chromium Bimetallic Nanoparticle Heterojunction Blend

“…The HR-TEM images of SnCr, P3HT and P3HT-SnCr revealed a broad size distribution and diameter ranging from 5 nm to 10 nm. The inset in Figure 5a corresponds to the selected area electron diffraction (SAED) of P3HT, showing a high degree of crystallinity [32][33]. This confirms that the material is composed of crystalline domains.…”

Improving the performance of ITO/ZnO/P3HT:PCBM/Ag solar cells by tuning the surface roughness of sprayed ZnO

“…Substrate temperature in this case was 250°C. A well-known and highly stable polymer, poly (3-hexylthiophene-2,5-diyl) (P3HT; regioregular, purchased from Rieke metals) with better stability and having its properties suitable for solar cell fabrication was chosen to form a blend with phenyl C60 butyric acid methyl ester (PCBMpurchased from Ossila) (Yanga et al, 2015) in 1:1 ratio; this was spin coated over the rough ZnO layer, to act as the active region. As the final stage of device fabrication, highly conducting silver was vacuum evaporated on to the polymer layer to act as the top electrode.…”

Morphological Stability of Organic Photovoltaics: Coarse‐grained Molecular Dynamics Simulation Studies

“…[11][12][13][14][15][16][17] On the other hand, research on the OPV stability has been relatively sparse although it is essential for its commercial application. 6,18,19 Recently, we have reported both experimental and computational studies about the effects of the number of OPV components on the OPV stability. 20 In this study, we have observed that a one-donor:two-acceptor (D:A 1 :A 2 ) OPV system shows higher stability than the binary (D:A 1 or D:A 2 ) systems.…”
