Title
Quantum well model of a conjugated polymer heterostructure solar cell
Abstract
In current study we analyzed the performance of a conjugated polymer heterostructured solar cell using quantum well representation for 100A thin polymer layers. The electrical field across the polymer layer is extremely strong to dissociate all excitons generated by sunlight. The behavior of free electrons appearing as a result of exciton dissociation was analyzed using wavefunctions and set of available energy levels. We came to the conclusion that small but finite probability exists to collect free electrons by the anode of the solar cell. The analyzed device was comprised of layers of bulk heterojunctions, namely, 100nm layers of poly[2-methoxy-5-(3',7'-dimethyloctyloxy)-1-4-phenylene vinylene]:phenyl C61-butyric acid methylester MDMO-PPV:PCBM (1:4), (poly-3-hexylthiophene): phenyl C61-butyric acid methylester P3HT:PCBM (1:1) and poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopen[2,1-b;3,4-b']dithiophene)- alt-4,7-(2,1,3-benzothiadiazole)] PCPDTBT:PCBM (1:3). Set of these layers are designed to be connected using transparent cathodes of lithium fluoride/aluminium/gold LiF/Al/Au, which are compatible with PCBM LUMO.
