Design and characterization of Bodipy derivatives for bulk heterojunction solar cells

Design and synthesis of soluble dibenzosuberane-substituted fullerene derivatives for bulk-heterojunction polymer solar cells

Fabrication and characterization of ZnTPP:PCBM bulk heterojunction (BHJ) solar cells

Bulk heterojunction (BHJ) solar cells were fabricated based on blended films of a porphyrin derivative 5,10,15,20-Tetraphenyl-21H,23H-porphine zinc (ZnTPP) and a fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) as the active layer. The ZnTTP:PCBM BHJ solar cells were fabricated by spin-casting of the blended layer. The weight ratios of ZnTPP and PCBM were varied from 1:1 t...

P3HT:PCBM Bulk Heterojunction Solar Cells Characterization by Spectroscopic EllipsometryOptical Discs

The performance of organic solar cells based on the blends of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) is strongly influenced by blend composition and thermal annealing conditions. For high-efficiency solar cells, a nanoscale interpenetrating network with crystalline order of both constituents is the desirable architecture for the photoactive layer. To...

Bulk Heterojunction Solar Cells — Opportunities and Challenges

Bodipy-backboned polymers as electron donor in bulk heterojunction solar cells.

Bodipy-based polymers, which possess a high absorption coefficient with a bandgap of approximately 1.6 eV, have been used as electron donor in solution-processed bulk heterojunction (BHJ) solar cells containing PCBM as acceptor. A power conversion efficiency (PCE) of approximately 2% has been achieved with V(oc) of approximately 0.8 eV and J(sc) of approximately 4.8 mA cm(-2).
