Organic solar cell by inkjet printing — An overview

Abstract

In recent years, Organic solar cells became more attractive due to their flexible power devices and the potential for low-cost. Inkjet printing is a very potential manufacturing technique of Organic solar cells because of its low material usage, flexibility and large area formation. In this paper, we presented an overall review on the inkjet printing technology as well as advantages of inkjet-printing and its potential for Organic solar cells (OSCs). Here we highlighted in more details about the viability of environment-friendly and cost-effective, non-halogenated ITO-free large scale roll to roll production of the organic solar cell by inkjet printing technology. The challenges of inkjet printing like the viscosity limitations, nozzle clogging, coffee ring effect as well as dot spacing are also discussed. Lastly, some of the improvement strategies for getting the higher efficiency of the OSCs have been suggested.
