TECHNOLOGY FOCUS - POLYMERS - Preferred Method: In the method (M1), the step of preparing further comprises: disposing at least one surface of the titanium electrode in an etching solution containing 0.48 vol% of hydrofluoric acid for time sufficient preferably for 30 seconds to properly etch the surface. In the method (M1), the step of depositing at least one layer further comprises: mounting a layer of donor/acceptor polymer on the surface of the titanium electrode; depositing at least one substantially transparent, hole-conducting polymer layer on a surface of the donor/acceptor polymer layer; mounting a buffer layer on the transparent, hole-conducting polymer layer; mounting a conducting layer on the buffer layer; and mounting a blocking layer on the conducting layer. In the method (M2), the step of depositing at least a first layer of PEDOT 1000 on a surface of the PEDOT 4083 layer opposite the P3HT:PCBM layer further comprises, depositing a second layer of PEDOT 1000 on the first layer of PEDOT 1000 and then depositing a third layer of PEDOT on the second layer of PEDOT 1000. Preferred Components: In the organic photovoltaic cell: the donor/acceptor layer comprises a P3HT:PCBM layer mounted on a first surface of the titanium electrode layer; and the hole-conducting polymer comprises at least one layer of PEDOT. In the organic photovoltaic cell, the layer of PEDOT further comprises: a layer of PEDOT 4083 mounted upon a surface of the P3HT:PCBM layer on an opposite side from the titanium electrode layer; the first layer of PEDOT 1000 mounted on a surface of the PEDOT 4083 layer opposite the P3HT:PCBM layer; and a silver paste mounted on the first layer of PEDOT 1000. The first layer of PEDOT 1000 is mounted on a surface of the PEDOT 4083 layer opposite the P3HT:PCBM layer further comprises a second layer of PEDOT 1000 mounted on the first layer of PEDOT 1000 and a third layer of PEDOT mounted on the second layer of PEDOT 1000.
