Investigation of low resistance transparent MoO3/Ag/MoO3 multilayer and application as anode in organic solar cells

Design of Transparent Anodes for Resonant Cavity Enhanced Light Harvesting in Organic Solar Cells

“…[14] In addition, several groups have shown promising results for tri-layer dielectricmetal-dielectric electrodes. [15][16][17][18] Here, building on the latter approach, a tri-layer electrode is proposed composed of a thin film of silver (Ag) sandwiched between two layers of molybdenum trioxide (MoO 3 ). The MoO 3 /Ag/MoO 3 transparent electrode is ITO-free, compatible with low-temperature substrates, and capable of alleviating the absorption-IQE trade-off by creating a resonant optical cavity to coherently trap light in the photoactive absorber.…”

J–V characteristics of dark and illuminated classical and inverted organic solar cells based on the CuPc/C60 heterojunction

“…We have shown that an ultra-thin metal film or a thin oxide film deposited onto the conductive substrate, whatever TCO can be used to improve the interface TCO/donor and therefore the devices performances [6][7][8]. Indeed, Au and/or MoO 3 allows achieving this goal [5], by simple vacuum deposition of an ultra-thin (0.5 nm) gold film or of a thin (3.5± 1 nm) MoO [9].There is a threshold silver thickness value, 10 nm, where the structures commute from an insulating state to a conductive state. We attribute this commutation to the percolation of the silver conducting path.…”

“…The electron donor is CuPc, the electron acceptor is C 60 , the buffer layer is Alq 3 [11,12]. The whole organic cells were prevented from air contamination by an amorphous selenium thin film [8,9,12]. The deposition conditions have been described earlier [17].…”

Influence of heat treatment on characteristics of In2O3/Ag/MoO3 multilayer films as transparent anode for optoelectronic applications

“…The conductivity of the multilayer system is essentially due to the metal film [26,27]. A homogeneous continuous layer of Ag has low absorption and excellent electrical conductivity.…”
