Photovoltaic properties of a sandwich cell consisting of bromophosphorus phthalocyanine and titanium dioxide layers

On doubts about Mott–Schottky plot of organic planar heterojunction in photovoltaic cell

“…A thin layer of Tc between PBrPc and Au should not limit the flow of holes from PBrPc to Au since it can be expected that the hole transporting levels of Tc and PBrPc coincide with each other. Therefore, Tc can be applied as a buffer layer between PBrPc which exhibits p-type electric transport, and Au in photovoltaic cells with organic heterojunction [16,17]. The average deposition rate of organic materials was equal to 0.5 Å/s.…”

Modification of the electronic properties of the TiO2 (110) surface upon deposition of the ultrathin conjugated organic layers

“…Modifying a semiconductor surface by an organic film overlayer is usually accompanied by interfacial chemical reactions and this may be a route for making new functional surfaces [2,3]. There are known efficient photovoltaic devices based on the interfaces between titanium dioxide and organic films [4,5]. A major role of the interface interaction and the interface potential barrier in photovoltaic properties observed was reported.…”

The photovoltaic effect in a heterojunction of molybdenyl phthalocyanine and perylene dye

“…For example, in [23,[27][28][29] this relation has been considered with respect to bulk heterojunction solar cells, while in [24,[30][31][32] it has been analyzed with respect to bilayer solar cells. Both m = 1 [29] and m > 1 have been observed [24,25,27,28]. A model of the photovoltaic effect in a bilayer organic system is presented below, enabling a qualitative interpretation of the U oc (I o ) dependence with m > 1.…”
