“…In 2008, Li et al 225 synthesised water/alcohol-soluble sulfonated poly(diphenylamine) (SPDPA) using a facile process for the sulfonation of polydiphenylamine (PDPA). The properties of SPDPA were observed to be distinct from its precursor PDPA, 226 showing better water solubility, slightly reduced conductivity, better thermal stability and blue-shifted optical absorption.…”

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.

“…To explore new AIL materials to substitute PEDOT:PSS, Li et al synthesized a water‐soluble polymer, SPDPA, by using oxidative polymerization coupled with a facile sulfonation process . The SPDPA could be dissolved in water as well as in polar organic solvents, in particular, the water‐processed SPDPA film appeared in a very smooth surface, together with the moderate conductivity (10 −4 S cm −1 ) and high transparency in the visible region.…”

With appropriate charge transport layers, one can rationally engineer the driving force, which generally refers to the built-in electric field in devices, so that electrons and holes can be effectively extracted to their respective electrodes, and thereby maximize the efficiency of OSCs. [4] There are two main types of charge transport materials that are commonly used in OSCs: anode interfacial layer (AIL) materials for hole collection and electron transport layer (ETL) materials for electron collection. However, at present, the development of AIL materials is comparatively lagging, as compared to ETL materials. For ETL materials, many materials, such as low-work-function metal, [5] small-molecule organic compounds, [6] nonconjugated and conjugated polymers, [7] and transition metal oxides (TMO), [8] have been proven effective in improving the electron collection efficiency in OSCs. In sharp contrast, only a few materials, such as poly(3,4ethylenedioxythiophene): (styrenesulfonate) (PEDOT:PSS) [9] and MoO 3 , [10] have been extensively used as AILs in OSCs. Generally, the AIL serves two functions: 1) Improving the selectivity and efficiency of hole transport and collection. First, by using AILs, the work function (W F ) of the anode can be effectively enhanced, which helps to construct a built-in electric field in the device with the combination of a low-W F cathode. The built-in electric field provides the fundamental driving force that transfers holes to the anode, where the holes are subsequently collected (Figure 1a). [11] Second, with the modification of the AILs, the W F of the anode can be enhanced to be higher than the positive integer charge-transfer state (E ICT + ) of the donor, in which case the Fermi-level pinning to the E ICT + level occurs to reduce the hole collection barrier at the anode interface (Figure 1b). [12] Third, AILs should effectively block the electrons, reducing the charge recombination at the interface. [13] 2) Improving the physical contact between the anodes and the active layers. With the modification of AILs, the hydrophilic surface of anodes can be changed, which enhances the wettability and film quality of the active layers deposited on the anode surfaces. Moreover, the anode surface can be smoothed by an AIL to passivate surface defects and pinholes, which decreases the leakage current of the OSC devices. To efficiently realize the above functions, AIL materials should possess several characteristics, including a high W F value, exceptional optical transparency, excellent hole In recent years, solution-processed conjugated polymers have been extensively used as anode interfacial layer (AIL) materials in organic solar cells (OSCs) due to their excellent film-forming property and low-temperature processing advantages. In this review, the authors focus on the recent advances in conjugated polymers as AIL materials in OSCs. Several of the main classes of solution-processable conjugated polymers, including poly(3,4-ethylenedioxythiophene):(styrenesulfonate), polyaniline, polyt...
