DOI: 10.1103/physrevb.99.205201
Abstract: We present an ab initio computational study of triplet exciton diffusion in four phosphorescent emitters commonly used in organic light-emitting diodes (OLEDs). By kinetic Monte Carlo simulations, triplet diffusion lengths are obtained for these emitters… read more here.

DOI: 10.1109/pvsc.2016.7749828
Abstract: We develop a method to quantify the local minority carrier diffusion lengths in interdigitated back-contact solar cells having a 10-μm-thick liquid-phase crystallized (LPC) Si absorber by light-beam induced current (LBIC) measurements. The method is verified… read more here.
