Neutron reflectivity studies on bulk heterojunction (BHJ) thin films
Polymer solar cells (PSCs) open up new perspectives in the solar cell market. The morphology of the active layer of PSCs plays a crucial role on the corresponding devices... -
Probing bulk heterojunction (BHJ) thin films with graded morphologies using SANS
This projects aims to contribute to a better understanding of the relationship between processing conditions, active layer morphology and device performance in polymer solar... -
Searching for a core-shell or multi shell structure in Stöber silica particles
We want to measure the SESANS from a series of large ~1 micron silica particles formed using the multistage Stöber method. The reason for this is to determine if we can see the... -
Controlling the morphology of fullerene-free polymer solar cells using additi...
We have recently demonstrated, using small angle neutron scattering in combination with other techniques, that in organic photovoltaic devices (OPVs) the additive... -
Neutron reflectivity study of the effect of thermal annealing on the morpholo...
This projects aims to contribute to a better understanding of the relationship between processing conditions, active layer morphology and device performance in polymer solar... -
Charge transport in PffBT4T-2OD and in the PffBT4T-2OD:PC71BM composite: a mu...
PffBT4T-2OD is one of the most recent and most successful low bandgap conjugated polymers used in organic photovoltaics - PffBT4T-2OD based OPV devices have power conversion... -
Controlling the morphology of bulk heterojunction (BHJ) films using mixtures ...
Through a combination of small angle neutron scattering, ion-beam analysis and ellipsometry we have recently demonstrated that in organic photovoltaic devices (OPVs) the... -
