“…Early studies of WSCPs and WSCSs as photoactive components in OSCs focused on the fabrication and examination of devices through layer-by-layer (LBL) processing from CPEs, and how this approach could allow comprehensive access to multilayer heterostructures with large donor/acceptor interfacial areas. [95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111] In spite of this, the electron-donating and electron-accepting layers in LBL devices were deposited alternately. The continuous pathways of transporting for respective charge carriers was hence completely interrupted, often leading to poor device performance.…”

Water/alcohol-soluble conjugated polymers (WSCPs) and small molecules (WSCSs) are materials that can be processed from water or other polar solvents. They provide good opportunities to fabricate multilayer organic optoelectronic devices without interface mixing by solution processing, and exhibit a promising interface modification ability for metal or metal oxide electrodes to greatly enhance the device performance of solar cells. Moreover, owing to their intriguing processability, WSCPs and WSCSs have great potential for applying environmentally friendly processing technologies to fabricate solar cells. In this review, the authors give an overview of recent developments in WSCPs and WSCSs, including their molecular design, material synthesis, functional principles and application as interface modification layers and photoactive components in emerging photovoltaic technologies such as organic/polymer solar cells, organic-inorganic hybrid solar cells and dye-sensitised solar cells.

“…106 Since Rubner and Tripathy et al's initial work, many have expanded upon the PPV and fullerene system. [107][108][109][110][111][112] Durstock and Chiang et al 111 engineered an interpenetrating heterojunction interface to increase the short-circuit current three times relative to a single, discrete heterojunction interface, an excellent example of how LbL architecture can be used to tune and tailor a device for optimal performance. In its simplest form, multilayers of PPV and PSS were first deposited on ITO, then multilayers of C 60 + and C 60 2 atop PPV-SPS to yield one heterojunction, or one interface of PPV and C 60 2 .…”

“…The multilayers were mainly based on fullerene derivatives as the electron acceptors. [59][60][61][62][63] It has been shown previously that the photocurrent generation and decay in polymer multilayers composed of poly(phenylenevinylene), poly(acrylic acid), poly(allylamine hydrochloride), and fullerene can be fitted to a biexponential function. The multilayer films were regarded as a capacitor in which the charging process corresponds to the photoinduced electrontransfer process.…”

Multilayer thin films were prepared by the layer‐by‐layer (LBL) deposition method using a rhenium‐containing hyperbranched polymer and poly[2‐(3‐thienyl)ethoxy‐4‐butylsulfonate] (PTEBS). The radii of gyration of the hyperbranched polymer in solutions with different salt concentrations were measured by laser light scattering. A significant decrease in molecular size was observed when sodium trifluoromethanesulfonate was used as the electrolyte. The conditions of preparing the multilayer thin films by LBL deposition were studied. The growth of the multilayer films was monitored by absorption spectroscopy and spectroscopic ellipsometry, and the surface morphologies of the resulting films were studied by atomic force microscopy. When the pH of a PTEBS solution was kept at 6 and in the presence of salt, polymer films with maximum thickness were obtained. The multilayer films were also fabricated into photovoltaic cells and their photocurrent responses were measured upon irradiation with simulated air mass (AM) 1.5 solar light. The open‐circuit voltage, short‐circuit current, fill factor, and power conversion efficiency of the devices were 1.2 V, 27.1 μ A cm−2, 0.19, and 6.1×10−3 %, respectively. The high open‐circuit voltage was attributed to the difference in the HOMO level of the PTEBS donor and the LUMO level of the hyperbranched polymer acceptor. A plot of incident photon‐to‐electron conversion efficiency versus wavelength also suggests that the PTEBS/hyperbranched polymer junction is involved in the photosensitization process, in which a maximum was observed at approximately 420 nm. The relatively high capacitance, determined from the measured photocurrent rise and decay profiles, can be attributed to the presence of large counter anions in the polymer film.
