Modeling spray coating and deposition of quantum-dot-sensitized nanoparticle thin film PV solar cells

Abstract

Among few available methods, spray deposition, if understood and controlled well, is a viable candidate for the fabrication of quantum dot (QD) sensitized nanoparticle PV solar cells.Spray coating is a multi-process method comprising proces � es such as atomization of a multicomponent liquid, droplet dynamics and flight, droplet evaporation, droplet impact on the surface, spreading, drying and adhesion of the solid content to one another and to the substrate. In this paper, a model is proposed that may be used as a design and research tool for the spray coating of QD-sensitized nanoparticle thin film solar cells. The model may be used to study the effect of processing parameters on the thin film characteristics and quality and to predict the ideal distance between the nozzle and the substrate and other optimum design conditions .. Index Terms -thin film solar cells, photovoltaic cells, quantum dot sensitized nanoparticle solar cells, spray coating and deposition.

Morphology, conductivity, and wetting characteristics of PEDOT:PSS thin films deposited by spin and spray coating

“…The cost of an all-solution-processed device is substantially reduced [24][25][26]. Spin-coating is an excellent technique to obtain high-quality multilayer thin films for solar cells, in small scale and for research purposes.…”
