: I will describe the use of carefully controlled optical excitation in conjunction with sensitive electronic detection to non-destructively measure fundamental properties of thin-film photovoltaics, such as the spatial variation of phase segregation, collection efficiency, and charge carrier mobility (see, for example, D. M. N. M. Dissanayake, A. Ashraf, Y. Pang, and M. D. Eisaman, Mapping Spatially Resolved Charge Collection Probability within Bulk Heterojunction Photovoltaics, Advanced Energy Materials, http://dx.doi.org/10.1002/aenm.201300525 (2013)). I will also describe our application of these ideas to the design of novel photovoltaic architectures.
