The Fate of Electron–Hole Pairs in Polymer:Fullerene Blends for Organic Photovoltaics

Jacques-Edouard Moser, Natalie Renuka Banerji, Jan Cornelius Brauer, Mariateresa Scarongella, Jelissa Risse, Natalie Stingelin, Martina Causa'

There has been long-standing debate on how free charges are generated in donor:acceptor blends that are used in organic solar cells, and which are generally comprised of a complex phase morphology, where intermixed and neat phases of the donor and acceptor ...

A Close Look at Charge Generation in Polymer:Fullerene Blends with Microstructure Control

Jacques-Edouard Moser, Natalie Renuka Banerji, Mariateresa Scarongella, Jelissa Risse, Natalie Stingelin

We reveal some of the key mechanisms during charge generation in polymer:fullerene blends exploiting our well-defined understanding of the microstructures obtained in pBTTT:PCBM systems via processing with fatty acid methyl ester additives. Based on ultraf ...

Using the Stark effect to understand charge generation in organic solar cells

Jacques-Edouard Moser, Natalie Renuka Banerji, Jelissa Risse, Natalie Stingelin

We have used a femtosecond-resolved spectroscopic technique based on the Stark effect (electromodulated differential absorption) in order to investigate free charge generation and charge drift in solar cell devices of neat conjugated polymer pBTTT and in i ...

The influence of microstructure on charge separation dynamics in organic bulk heterojunction materials for solar cell applications

Jacques-Edouard Moser, Natalie Renuka Banerji, Arun Aby Paraecattil, Mariateresa Scarongella, Natalie Stingelin

Light-induced charge formation is essential for the generation of photocurrent in organic solar cells. In order to gain a better understanding of this complex process, we have investigated the femtosecond dynamics of charge separation upon selective excita ...
