Solar Cells: Spin-Cast Bulk Heterojunction Solar Cells: A Dynamical Investigation (Adv. Mater. 13/2013)

Spin-enhanced organic bulk heterojunction photovoltaic solar cells.

Recently, much effort has been devoted to improve the efficiency of organic photovoltaic solar cells based on blends of donors and acceptors molecules in bulk heterojunction architecture. One of the major losses in organic photovoltaic devices has been recombination of polaron pairs at the donor-acceptor domain interfaces. Here, we present a novel method to suppress polaron pair recombination a...

Hydrogen bonding in bulk heterojunction solar cells: A case study

Small molecules with dithieno[3,2-b;2',3'-d]thiophene as central building block and octyl cyanoacetate and octyl cyanoacetamide as different terminal building blocks have been designed and synthesized. The amide containing small molecule can form intermolecular hydrogen bonding between N-H...O = C of the amide group. The photovoltaic properties and active layer morphologies of the two molecules...

Nanofi ber - Based Bulk - Heterojunction Organic Solar Cells

Bulk heterojunction organic photovoltaic (BHJ–OPV) devices have been the topic of ever increasing research efforts due to their potential to result in printable, inexpensive solar cells which can be processed onto fl exible substrates. [ 1–3 ] Typically, the active layer of the BHJ consists of an interpenetrating network of electrondonating conjugated polymers and electron-accepting fullerenes....
