Characteristics of curcumin dye used as a sensitizer in dye-sensitized solar cells

Abstract

Dye-sensitized solar cells are the closest mankind has come to replicating nature's photosynthesis. The type of a dye influences the efficiency of these cells. In this paper we studied curcumin dye as a sensitizer in dye-sensitized solar cells and compared it with most often used cyanidin. The results have shown that curcumin has higher efficiency and higher absorption in the visible part of the spectrum compared to cyanidin. Simulation models of dye molecules, curcumin and cyanidin, are deprotonated upon adsorption on the titanium dioxide surface. The energy levels obtained from the calculation indicate a higher probability of electron transition from molecule to titanium dioxide surface in case of curcumin than in case of cyanidin. Based on these results, we concluded that curcumin dye has better properties as sensitizer in dye-sensitized solar cells.

“…Curcumin has also been investigated to develop novel materials employed in various applications in chemical sensing (colorimetric sensor for copper, hemoglobin, and pH colored sensor), drug delivery applications as carrier, radical scavengers, environmental remediation, [ 97 ] and photosensitizers in dye‐sensitized solar cells (DSSC) [ 98–100 ] and photodynamic therapy. [ 50,101 ] Despite the reported broad spectrum of promising properties, the practical use of curcumin especially in bio‐applications has been hampered due to its disadvantageous physicochemical properties (extremely low solubility in aqueous media, instability), poor bioavailability, and rapid metabolism.…”

“…Additionally, curcumin‐ FSM bio‐aerogels can be of great importance as novel material for the various applications reported for curcumin in, for example, in field of DSSC, [ 98–100 ] chemical sensing, radical scavengers, environmental remediation, [ 97 ] and photodynamic therapy. [ 50,101 ]…”

“…Recently, curcumin has gained an increased interest for applications in nutrition and medicine due to the accumulated body of evidence and recent studies reporting various health promoting and pharmacological activities of curcumin, such as anticancer [94] (for many types of cancers including colorectal, breast, lung, prostate and pancreatic carcinoma), anti-inflammatory, [95] anti-oxidant, prevention and treatment of Alzheimer's disease. [96] Curcumin has also been investigated to develop novel materials employed in various applications in chemical sensing (colorimetric sensor for copper, hemoglobin, and pH colored sensor), drug delivery applications as carrier, radical scavengers, environmental remediation, [97] and photosensitizers in dye-sensitized solar cells (DSSC) [98][99][100] and photodynamic therapy.

“…Some biopolymers, such as mucilage have some mucoadhesive properties, which can also be used for prolonged residence/contact of drug delivery systems on the mucosal surfaces improving the prolonged drug release and delivery. [67,104] Additionally, curcumin-FSM bio-aerogels can be of great importance as novel material for the various applications reported for curcumin in, for example, in field of DSSC, [98][99][100] chemical sensing, radical scavengers, environmental remediation, [97] and photodynamic therapy.
