First claim
Opening claim text (preview).
What is claimed is: 1. A derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer having the formula wherein n is equal to about 1 to about 100. 2. The derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer of claim 1 , wherein n is equal to about 10 to about 30. 3. The derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer of claim 1 , wherein n is equal to about 1 to about 50. 4. A bulk heterojunction material, comprising: a) a derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer as in claim 1 as a donor; and b) an acceptor. 5. The bulk heterojunction material of claim 4 , wherein the acceptor is selected from the group consisting of PC70BM, BisIndene-C70, BisPC70BM, BisBenzene-C70, TrisPC70BM and PC76BM. 6. An organic solar cell device comprising: a) a silver layer; b) a bulk heterojunction layer, wherein the bulk heterojunction layer comprises: i. at least one derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer as in claim 1 as a donor; and ii. an acceptor; and c) an indium tin oxide glass layer. 7. The organic solar cell device of claim 6 , wherein the acceptor is selected from the group consisting of PC 70 BM, BisIndene-C 70 , BisPC 70 BM, BisBenzene-C 70 , TrisPC 70 BM and PC 76 BM. 8. The bulk heterojunction material of claim 4 , wherein, in the derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer of claim 1 , n is equal to about 10 to about 30. 9. The bulk heterojunction material of claim 4 , wherein, in the derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer of claim 1 , n is equal to about 1 to about 50. 10. The organic solar cell device of claim 6 , wherein, in the derivatized benzo[1,2-b:3,4-b]dithiophene-thienothiophene based polymer of claim 1 , n is equal to about 10 to about 30. 11. The organic solar cell device of claim 6 , wherein, in the derivatized benzo[1,2-b:3,4-b′]dithiophene-thienothiophene based polymer of claim 6 , n is equal to about 1 to about 50.
