High-efficiency and low-cost photovoltaic technologies are still required to successfully replace fossil fuels in the US. As recently suggested by the National Renewable Energy Laboratory (NREL) Renewable Electricity Futures Study, by the year 2050, 80% of the power generated in the US could be from renewable sources. For that, photovoltaic generation must increase to >10% of the energy produced today. The main challenge to achieve this goal is the current high cost/Watt: $5.3/W for <10kW systems, and $2.5/W to $4.0/W for utility-scale systems. Thus, we are currently focusing on advancing the understanding of the physical behavior of materials with potential for high-performance photovoltaics. These materials are often composed by mesoscale constructs, which require identifying the causes for spatial variations and degradation (failure). I will present a platform for functional imaging of materials for sustainability, ranging from photovoltaics to energy storage. Further, in order to draw immediate attention of lay audiences we correlate scientific findings to animated visualizations, which will be shared during the presentation.
