The unique temperature-dependent solubility of liquid crystalline poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2b]thiophene) (PBTTT) enabled us to construct the first bilayer-bulk-heterojunction devices based on a PBTTT: PCBM (1:2)/MDMO-PPV:[70]PCBM (1:4) active layer. The bilayer device exhibited an extended optical absorption over the solar spectrum and concentration gradient that enhanced char...

Hybrid thin film solar cell based on all-inorganic nanoparticles is a new member in the family of photovoltaic devices. In this work, a novel and performance-efficient inorganic hybrid nanostructure with continuous charge transportation and collection channels is demonstrated by introducing CdTe nanotetropods (NTs) and CdSe quantum dots (QDs). Hybrid morphology is characterized, demonstrating a...

Structural development of porphyrin-based small molecules as electron donors and acceptors leads to optimal photovoltaic performances, with PCEs over 12% 9.6%, respectively, in bulk-heterojunction organic solar cells.
