Improving the Reproducibility of P3HT:PCBM Solar Cells by Controlling the PCBM/Cathode Interface
Plastic photovoltaic devices offer a real potential for making solar energy economically viable. Unfortunately, bulk heterojunction (BHJ) solar cells fabricated from blends of the commonly used materials poly(3hexylthiophene), P3HT, and phenyl-C61-butyric acid methyl ester, PCBM, sometimes exhibit low efficiencies even when the procedures followed often produce solar cells with efficiencies exc...
متن کاملHighly efficient exciton harvesting and charge transport in ternary blend solar cells based on wide- and low-bandgap polymers.
We have designed highly efficient ternary blend solar cells based on a wide-bandgap crystalline polymer, poly(3-hexylthiophene) (P3HT), and a low-bandgap polymer, poly[(4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2'3'-d]silole)-2,6-diyl-alt-(2,1,3-benzothiadiazole)-4,7-diyl] (PSBTBT), and a fullerene derivative (PCBM). By using highly crystalline P3HT, high fill factors were obtained even for ternary ...
متن کاملMapping the Competition between Exciton Dissociation and Charge Transport in Organic Solar Cells.
The competition between exciton dissociation and charge transport in organic solar cells comprising poly(3-hexylthiophene) [P3HT] and phenyl-C61-butyric acid methyl ester [PCBM] is investigated by correlated scanning confocal photoluminescence and photocurrent microscopies. Contrary to the general expectation that higher photoluminescence quenching is indicative of higher photocurrent, microsca...
متن کاملTuning the energy level offset between donor and acceptor with ferroelectric dipole layers for increased efficiency in bilayer organic photovoltaic cells.
Ultrathin ferroelectric polyvinylidene fluoride (70%)-tetrafluoroethylene (30%) copolymer film is inserted between the poly3(hexylthiophene) (P3HT) donor and [6,6]-phenyl-C61-butyric acid methylester (PCBM) acceptor layers as the dipole layer to tune the relative energy levels, which can potentially maximize the open circuit voltage of bilayer organic solar cells. In this work, the power conver...
متن کاملمطالعه رسانایی جریان مستقیم لایه‌های نازک P3HT آلاییده با نانو ذرات ZnS و Ag
Interest in the P3HT: ZnS nanocomposites are increased due to their applicability as an active layer for bulk heterojunction solar cells of high open circuit voltage and charge transport in this type of solar cells determines their performance. So the study of the conduction mechanism of the P3HT:ZnS nanocomposites is significant to improve the efficiency of such solar cells, and this paper dis...
