Embodiment 1
[0250] Example 1. Fabrication of organic photovoltaic cells subjected to non-solvent surface treatment methods
[0251] The organic photovoltaic cell has a structure of ITO / PEDOT:PSS / photoactive layer (polymer 1 as follows: PCBM) / Al. The glass substrate on which ITO was applied was ultrasonically cleaned using distilled water, acetone and 2-propanol, and the ITO surface was treated by ozone for 10 minutes, followed by spin-coating with PEDOT:PSS (Clavios AI4083) at a thickness of 26 nm at 200 °C Heat treatment for 5 minutes. A mixture of the following polymer 1 and PCBM mixed in a ratio of 1:1.75 was formed for coating of a photoactive layer, and spin coating was performed with a thickness of 100 nm to form a photoactive layer. Methanol was applied onto the photoactive layer, and spin coating for a non-solvent surface treatment method was performed at 5000 rpm, thereby removing the non-solvent. Use a thermal evaporator at 3 x 10 -6 Al was deposited under a Torr vacuum to a ...
Embodiment 2
[0254] Example 2. Fabrication of organic photovoltaic cells subjected to non-solvent surface treatment methods
[0255] The same method as in Example 1 was carried out except that 2-methoxyethanol was used instead of methanol.
