Otherwise, the cell process is similar to that used for crystalline Si solar cells and, in spite the efficiency of this type of cells is less than 2-3% in relation to crystalline

Although these fabrication conditions yielded the best performing device during this work, it is believed that the use of Ethyl acetate as anti-solvent can further improve
