A facile and convenient synthesis and photovoltaic characterization of novel thieno[2,3-b]indole dyes for dye-sensitized solar cells

Novel push-pull thieno[2,3-b]indole-based dyes for efficient dye-sensitized solar cells (DSSCs)

“…It is important to note that only formal applicability of dyes IK 1 and 2 as sensitizers for DSSCs has been shown in our previous work. 17 In particular, PCE values of the obtained solar cells were very low (PCE = 0.37 % for IK 1; PCE = 0.79% for IK 2). These low PCE values were attributed to a number of defects of TiO2 photoanodes, which were manufactured and used in that study.…”

“…DSSCs were fabricated using the synthesized dyes IK 3-6, as photosensitizers, and their photovoltaic properties were measured under standard global AM 1.5 irradiation (100 mW cm 2 ). In addition, DSSCs based on recently described sensitizers IK 1 and 2, 17 that represent a structurally close series of thieno [2,3-b]indole dyes, were also tested under similar experimental conditions. It is important to note that only formal applicability of dyes IK 1 and 2 as sensitizers for DSSCs has been shown in our previous work.…”

“…These low PCE values were attributed to a number of defects of TiO2 photoanodes, which were manufactured and used in that study. 17 In contrast, the manufacturing technique of TiO2 electrodes has been significantly improved during current research, which allowed us to obtain photovoltaic devises based on the investigated dyes with better PCE characteristics. Furthermore, the photosensitize capabilities of all IK dyes have been compared with commercial ruthenium dye N3 cell performance.…”

One-pot multicomponent synthesis of thieno[2,3-b]indoles catalyzed by a magnetic nanoparticle-supported [Urea]4[ZnCl2] deep eutectic solvent

“…Thieno [2,3-b]indoles are common structural motifs in a variety of biological activities and therapeutically useful compounds leading to potential applications in treating epilepsy, neurological diseases, 1 plant-growth regulatory properties, 2 battery devices, [3][4][5][6][7] and polymer conductors. 4 Due to the potential applications of thieno [2,3-b]indoles, the development of new and efficient synthetic protocols for these compounds has received considerable attention.…”

A new and convenient synthetic way to 2-substituted thieno[2,3-b]indoles

“…Another promising area for the use of thieno[2,3- b ]indoles, as electron-rich heteroaromatics, is the design of photo- and electroactive compounds which can be applied in organic optoelectronic materials. Indeed, we have recently reported the synthesis of novel push–pull dyes IK-1,2 based on the thieno[2,3- b ]indole ring system, as a donating part of dye-sensitized solar cells [ 8 ] ( Fig. 1 ).…”
