Solid-state organic/inorganic hybrid solar cells based on conjugated polymers and dye-sensitized TiO2 electrodes

Functional coatings: The sol-gel approach

“…A large number of alternative solutions have been proposed. These include replacing the liquid redox electrolyte with, for instance, molecular or macromolecular organic hole conductors such as triphenyldiamine-, polypyrrole- [44], and p-phenylene vinylene-based copolymers [45] or substituted polythiophenes [46].…”

Plasma-enhanced polymerized aniline/TiO2 dye-sensitized solar cells

“…In order to complete the charge transfer mechanism, these dye-sensitized electrodes are usually combined either with a hole conducting material or a iodide (I − )/triiodide (I 3 − ) redox couple as an electrolyte [2,3]. Conducting polymers such as polythiophene, polypyrrole, polyphenylene vinylene (PPV), polyaniline, and their derivatives are all used as hole conductors for the fabrication of efficient DSSCs [4][5][6][7][8][9][10][11][12][13]. These conducting polymers with extended conjugated electron systems have seemed to be the promising materials because of their high absorption coefficients in the visible region of the spectrum and high mobility of the charge carriers.…”

Preparation and photoelectrochemical performance of TiO2/Ag2Se interface composite film

“…Since Grätzel et al introduced the special organic dye into the nanostructured TiO 2 electrode, significant progress has been made in the fabrication of dye-sensitized solar cell [3][4][5][6] . In order to overcome the instability of the organic dyes, recently, some semiconductors with narrow band gap (BG) have been introduced to the solar cell based on the nanostructured TiO 2 .…”
