NOVELTY - A laminated polymer membrane solar battery comprises a base plate (1), an indium-tin oxide cathode layer (2), a sub-battery electron transmission layer (3), a sub-battery photosensitive layer (4), a sub-battery hole transmission layer (5), a semi-transparent anode (6), a sub-battery hole transmission layer (7), a sub-battery photosensitive layer (8), and a cathode (9). Layer (4) contains conjugated polymer and fullerene derivative. The conjugated polymer is (2,6-(4,4-bis-(2-ethylhexyl)-cyclopentadithiophene)-4,7-(2,1,3-benzothiadiazole).    USE - Laminated polymer membrane solar battery with shunt-wound structure.    ADVANTAGE - The laminated polymer membrane solar battery has excellent energy-conversion efficiency and current carrier collection efficiency.    DETAILED DESCRIPTION - A laminated polymer membrane solar battery with shunt-wound structure, comprises a transparent base plate made of glass or plastic, an indium-tin oxide cathode layer having a thickness of 150 nm, sub-battery electron transmission layer made of n-type metal oxide titanium oxide, zinc oxide, and/or tin oxide having a thickness of 10-50 nm, sub-battery photosensitive layer, sub-battery hole transmission layer, a semi-transparent anode, sub-battery hole transmission layer, sub-battery photosensitive layer, and a cathode. Layer (4) contains a mixture of conjugated polymer and fullerene derivative. The conjugated polymer is (2,6-(4,4-bis-(2-ethylhexyl)-cyclopentadithiophene)-4,7-(2,1,3-benzothiadiazole) as light-absorbing and electron-donor material, and the fullerene derivative is (6,6)-phenyl-61C-methylbutyrate (PCBM) as electron-acceptor material. The mass of fullerene derivative is 40-80% of the total mass of the mixture. Layer (4) has a thickness is 100-150 nm. The material of layer (5) is p-type metal oxide chosen from molybdenum oxide and tungstic oxide, and has a thickness of 10-20 nm. The semi-transparent anode is made of superpower function metal gold, nickel, and/or silver, and has a thickness of 10-20 nm. Layer (7) is made of p-type metal oxide chosen from molybdenum oxide and tungstic oxide, and has a thickness of 10-20 nm. Layer (8) contains a mixture of conjugated polymer and PCBM. The conjugated polymer is 3-decoylthiophene (P3HT) as light-absorbing and electron-donor material. The mass of PCBM is 40-80% of the total mass of the mixture. Layer (8) has a thickness of 100-200 nm. The cathode is made of metal aluminum and/or calcium, and has a thickness of 60-200 nm. Layers (1-9) are connected in sequence. Two sub-batteries are overlapped in the direction vertical to the base plate and connected in parallel to form the laminated polymer membrane solar battery with shunt-wound structure.
