Organic photovoltaic devices based on polyazomethine and fullerene

New environmentally friendly polyazomethines with thiophene rings for polymer solar cells

“…For photovoltaic applications, some researchers have propose the use of polyazomethines as the donor in the active layer (Sharma et al, 1996;Hindson et al, 2010;Iwan et al, 2012Iwan et al, , 2013aIwan et al, ,b, 2011Iwan et al, , 2014dPalewicz et al, 2011). The first study of polyazomethines for solar cells was published by Sharma et al (1996).…”

Enhanced power conversion efficiency in bulk heterojunction solar cell based on new polyazomethine with vinylene moieties and [6,6]-phenyl C61 butyric acid methyl ester by adding 10-camphorsulfonic acid

“…Instead of P3HT and PCDTBT other polymers and copolymers with thiophene, vinylene, benzothiadiazole, carbazole and azomethine units (e.g. [13][14][15][16][17][18][19][20]72,73]) have been investigated in polymer photovoltaics taking into consideration their thermal and air stability.…”

“…[3,4,[9][10][11][12]). At the last time some researchers propose to use them as a donor in the active layer of polymer solar cells [13][14][15][16][17][18][19][20].…”

Comprehensive UV–Vis and EPR spectroelectrochemical characterization of ambipolar azomethinenaphthaldiimides

“…For example, polythiophenoazomethines derivatives were found to be both p-and n-conjugated materials with electrochromic properties [39,40]. It is known that compounds with this type of moieties in their structures might be applied in organic (opto) electronic devices, for example in solar cells [41] or field effect transistors (FETs) [42]. Taking into account all the facts described above, we decided to undertake the investigations of naphthalene diimide derivatives substituted with imine units.…”
