Dispersions of molecular or nanoscale precursors such as chalcogenidometallates and colloidal quantum dots are currently being explored as solution processable precursors to semiconducting films. Solution-based processing can provide enormous cost benefits for large-area and high-volume electronic applications such as thin-film transistors, photovoltaics, and thermoelectrics. We recently reported the synthesis of large-grained (>500 nm) CdTe thin films from colloidal quantum dot precursors that were integrated into photovoltaic devices with >12% power conversion efficiency.1 I will summarize our recent efforts in creating semiconducting solids from solution-processable precursors and their applications in electronic devices.
