Review on Printing and Coating Method for Fabrication of Polymeric Solar Cells

Polymer solar cells commonly are made of optically active thin film between two electrodes. Film forming technique such as spin coating, doctor blading and casting are used currently for high volume optically active layers production. From a processing point of view, other film-forming techniques such as gravure coating, off-set coating, spray coating and printing technique such as inkjet printing, pad printing and screen printing are favorable to the formation of thin film for polymer solar cells. In this paper, entire process leading to polymer solar cells are investigated with focus on the materials, available techniques and particular advantages and disadvantages associated with each case
