TEY-STXM confirms homogeneous doping of nanoparticles for non-fullerene organic solar cells

One of the challenges in modern research on the fabrication of non-fullerene acceptor based organic solar cells is the availability of very efficient hole transport layers (HTLs). A new approach that avoids mutual solubility issues is to deposit the HTL from a suspension of doped organic nanoparticles. Surface-sensitive TEY-STXM measurements at the PolLux beamline characterised the homogeneity of the dopant in the nanoparticles and develop efficient nanoparticle HTL materials for organic solar cells.
