Spray coating: A fabrication method for large area organic solar cells and a tool for rapid screening of new materials
Abstract
Spray coating is investigated as a fabrication method for large area organic solar cells. The process is a general coating method which can easily produce uniform large area coatings on various substrates including non-flat and flexible substrates. We have used the process to fabricate the photo-active layer of organic solar cells as well as conducting polymer electrodes. To demonstrate the scalability of the spray process, a spray coating machine with motorized spray nozzle has been prepared and used to fabricate 10 x 10 cm organic solar cell modules. Various device structures, deposition parameters and materials are studied. The relationship between efficiency and the parameters will be presented. The coating method is also investigated as a tool for screening new materials for organic solar cells. Unlike spin coating, which is the most common method used to make the photo-active layer of organic solar cells, spray coating can produce a wide range of thicknesses from a solution without changing the concentration. The target thickness was obtained by controlling the number of spray depositions or the deposition time, and the thickness was monitored in-situ. Optimization processes and results with new materials will be presented.
