The area of organic photovoltaic materials has elicited great interest in both the scientific and technological communities due to its potential to deliver cheap and highly efficient solar cells [1] . To date, however, such so-called molecular wires have typically yielded energy conversion efficiencies of only~5-6% despite a theoretical maximum of 13% [2] . We present an approach that uses a genetic algorithm to search the space of synthetically accessible molecular wires for those with optimal
more &raquo; ... electronic structures. This approach combines both cheminformatics (SMILES to 3D using OpenBabel) and computational chemistry (semi-empirical calculations using Gaussian09). Using this method, we have found hundreds of candidates with predicted efficiencies over 8% including many with efficiencies over 10%.
