摘要: Embodiments of the invention are directed to random conjugated copolymers comprising a plurality of one or more different donor (D) repeating units and a plurality of at least one acceptor (A) repeating unit. At least one of the D units has a solubilizing substituent, statistically a portion of the A repeating units are separated from each other by only one D units and a plurality of the A unit are adjacent to one the D units having the solubilizing substituents. The random conjugated copolymers are black or colored in the neutral state and highly transmissive in the oxidized state. The random conjugated copolymers have the structure -[(D)xA]n-, where x>1 and n(x+1)≧10 or the structure -[(DA))x-(D′Ay]n-, where D represents one substituted D unit and D′ represents another D units and where x≧1, y≧1 and 2n(x+y)≧10. Other embodiments of the invention are directed to forming the -[(D)xA]n- or -[(DA)x-(D′A)y]n- random conjugated copolymers by condensation polymerizations between monomers containing complementary reactive groups.

摘要: A polymer based solar cell having an inverted geometry includes a transparent cathode and a double interlayer that has a hole extracting layer and a hole transport/electron blocking layer situated between an active layer, for example, a bulk heterojunction (BHJ) layer, and an anode. The inverted solar cells according to embodiments of the invention display significant efficiency improvements over polymer based solar cells that do not have the inverted geometry and lack the double interlayer.
