Synthesis of metal free organic dyes: Experimental and theoretical approach to sensitize one-dimensional cadmium sulphide nanowires for solar cell application

Eosin‐G and ethyl eosin dye sensitized CdS nanowires towards dye sensitized solar cells applications

“…In contrast, the CdS NWs + ethyl eosin device showed the highest power conversion efficiency of 0.328%, which might be due to the higher LUMO energy level of ethyl eosin when compared to eosin-G (Figure 6B), resulting in better charge separation and reduced recombination at the interface between the dye and the NWs, leading to higher photocurrent and power conversion efficiency.

“…Recently, our group [39] achieved photoelectrochemical (PEC) sensitization of CdS NWs using rhodamine B and rose bengal dyes, yielding efficiencies of 0.120% and 0.125%, respectively. Bayannavar et al [40] synthesized phenothiazine dyes containing rhodanine-3-acetic acid (PDR) and pyridine (PDP) as the anchoring groups and reported efficiency of 0.239% and 0.277% for PDR and PDP, respectively. Wagalgave et al [41] have designed and synthesized two new diketopyrrolopyrrole (DPP)-merocyanine (MC)-based dyes termed as DPP1 and DPP2, used them in DSSCs application, and reported maximum efficiencies of 0.195% and 0.268%, respectively.…”

A new biosynthesis of CuCo2S4 nanoparticles as a high‐performance supercapacitor electrode and excellent non‐enzymatic hydrazine sensor

“…In fact, nanomaterials have gained interest for their promising energy applications, such as electrochemical energy storage [3,4] and hydrogen storage [5]. Metal sulphides have been recently used in various application fields such as photocatalyst [6,7], catalyst [8], photovoltaic [9], anti-bacterial activity [10,11], energy storage devices [12,13,14] and non-enzymatic sensors [15,16,17].…”
