A simple fluorene core-based non-fullerene acceptor for high performance organic solar cells

A small molecule non-fullerene acceptor based on a fluorene core having a furan π-spacer and end capped with rhodanine (FRd2) is developed for solution processable bulk heterojunction organic solar cells (OSCs). The simplistic synthetic protocol reduces several reaction steps and hence production cost. Extended π-conjugation via furan units and the presence of electronegative rhodanine groups result in a power conversion efficiency of 9.4% in OSCs, which is the highest so far among these categories of molecules.

Low glass transition temperature hole transport material in enhanced-performance solid-state dye-sensitized solar cell Prof. Gregory L. Baker passed away on Oct. 18. 2012. We dedicate this work as a memorial to him.

A new triarylamine-based hole transport materials (HTM) with branched side chain giving low glass transition temperature (Tg) is synthesized and incorporated into a solid state dye sensitized solar cell. This designing of molecular structure of HTM for lowering the Tg along with viscosity and surface tension of the casting solution effectively increases the pore-filling fraction (PFF) as the cell is heated during the fabrication, leading to an 8 fold increasing in cell efficiency over cells without heat treatment. We relate the cell performance improvement not only due to the PFF of TiO2 by the (HTM), but also because of morphological and thickness changes in the hole transport material (HTM) capping layer.

Indan-1,3-dione electron-acceptor small molecules for solution-processable solar cells: A structure-property correlation

A structure-device performance correlation in bulk heterojunction solar cells for new indandione-derived small molecule electron acceptors, FEHIDT and F8IDT, is presented. Devices based on the former exhibit higher power conversion efficiency (2.4%) and higher open circuit voltage, a finding consistent with reduced intermolecular interactions.
