Integration of polyelectrolyte based electrochromic material in printable photovoltaic electrochromic module

Chemical potential–electric double layer coupling in conjugated polymer–polyelectrolyte blends

“…This has significant implications on how the nature of electrochemical doping in CPs should be perceived, because it makes a strong argument for a view of spatially separated electronic and ionic charge carriers, in contrast to the classical view of doping as an electrochemical redox process ( 35 ). Although PEDOT:PSS, which is the most prevalent CP-PE blend, was used for comparison with the model in this work, other materials such as polypyrrole:PSS ( 36 ), polyaniline:PSS ( 37 ), and thiophene with glycolated side chains ( 38 ) show similar CV characteristics. The model is thus expected to be useful for a wider class of blends than just PEDOT:PSS.…”

Recent Developments of the Solution-Processable and Highly Conductive Polyaniline Composites for Optical and Electrochemical Applications

“…The PSS, a vinyl polymer having sulfonate (−SO 3 − ) groups promotes para-directed polymerization of aniline, which resulted in the formation of PANI with lower structural defects . A water-soluble PANI:PSS was proposed as an alternative to substitute PEDOT:PSS with high cost and poor redox behaviors [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. The synthesis of PANI:PSS NPs was proposed by simple chemical oxidative polymerization of aniline in the presence of the PSS (Figure 8) [24][25][26][27][28].…”

“…Furthermore, the −SO 3 − groups of PANI:PSS enable electrostatic interactions with various materials, such as carbons, inorganics, and polymers [20][21][22][30][31][32][33][34][35][36][37]. Therefore, various PANI:PSS-based composites were designed for SCs [23,[25][26][27], ECs [28][29][30], supercapacitors [31][32][33][34], sensors [22,24,35,36], antennas [37], and so forth. It was obvious that the PANI:PSS can act as an efficient hole transport layer (HTL) material in perovskite solar cells (PSCs) and organic solar cells (OSCs) [23,25,26].…”

“…A multi-color EC window using the Prussian blue (PB)-PANI:PSS nanocomposite exhibited an average transimittance (∆T ave ) of 52.3%, bleaching time of 8.1 s, and darkening time of 13.3 s (Figure 9a) [28]. A photovoltaic-electrochromic (PV-EC) module that was based on PANI:PSS worked by the irradiation of sunlight, and the PV-EC based on PANI:PSS exhibited color changes by tuning the oxidation level of PANI [29]. PANI:PSS/GS composites offer the synergies of psuedocapacitive and electric double-layer (EDLC) mechanisms, which results in improved cycling stability and higher power density [31,32].…”

A fast self-charging and temperature adaptive electrochromic energy storage device

“…[4][5][6][7][8][9][10][11][12] However, in harsh environments or remote areas, the power grid is unavailable, which limits the charging and reuse of electrochromic energy storage devices. To solve this issue, various energy harvesting technologies, such as photovoltaic devices, 13,14 friction generators, 15,16 piezoelectric generators, 11 etc., were integrated with electrochromic energy storage devices into self-charging power systems. However, these systems are highly dependent on energy resources, which are not always available in certain environments or specic time periods.…”
