Abstract

Recently, Quantum dot-based solar cells (QDSCs) as the third-generation solar cell are attracting considerable attention in many photovoltaic researches. CdSe quantum dots (or nanocrystals) have been exploited in many studies as inorganic dye to sensitize TiO2 thin films in QDSCs due to their unique properties for harvesting energy and enhancement efficiency in converting solar energy to electricity. As yet, various researches have been conducted with different results in order to increase the efficiency of this type of solar cells. This paper reports investigation of the influence of 2 wt.% graphene nanoparticles in the TiO2 semiconductor layer on the performances of CdSe-QDCs. At 1 sun illumination condition, the efficiency η ranged from 0.03 to 0.11%. Also, obtained results showed reduction the parasitic resistances effects such as series and shunt resistances. The electron diffusion coefficient Dn and lifetime τn are determined from the non-linear least squares fitting method at open circuit voltage decay under the Nd:YAG laser pulses. The results and analysis from measurements show increasing the Dn, τn, electron mobility µ, and diffusion length Ln. As the result, investigations indicative the reduction of recombination centers due to specific electrical properties of the graphene nanoparticles and improvement performance of this type of solar cell.
