There is a clear need for well-controlled synthetic methods for compositionally complex semiconductor nanoparticles with interesting properties.  As the composition of the nanoparticles increases in complexity, however, one could expect that significant disorder can occur.  This talk will focus on our efforts to develop syntheses for the phase-pure synthesis of a family of transition metal chalcogenides composed of earth abundant elements.  In particular, we are interested in compounds with direct band gaps that could have applications in photovoltaics. In this talk we will show data linking the photovoltaic performance of thin films made from these nanoparticles with the structural and electronic properties of the particles themselves, and use these data to propose next steps for the development of colloidal nanoparticles for photovoltaics. <br/>
