Nanoparticle (NP) solar cells show the promise to enhance the efficiency of solar cells over the Shockley-Queisser limit due to quantum confinement enhanced charge multiplication processes . A fundamental challenge of NP solar cells, however, is that the very reason that leads to enhanced charge generation also tends to hinder charge transport. To address this challenge, we outline a multi-scale transport modeling scheme based on our previous calculations  that involves determining NP parameters from ab-initio and semi-empirical calculations, such as energy level structures, charging energies. This is then embedded in a Kinetic Monte Carlo hopping transport framework to calculate electron and hole mobilities in NP devices as a function composition, disorder, temperature. As a first demonstration, we apply our method to PbSe NP Schottky devices.\\[4pt] Work done in collaboration with Ian Carbone, Physics Department, University of California, Santa Cruz and Marton Voros, Physics Department, University of California, Davis.\\[4pt]  Matthew C.
