High throughput experimental (HTE) techniques are an increasingly important way to accelerate the rate of materials research and development for many possible applications. However, there are very few publications on the reproducibility of the HTE results obtained across different labs for the same materials system used in the same application. Here, we report on an comparative high throughput experimental Study of Zn-Sn-Ti-O thin films materials synthesized and characterized at National Institute of Standards and Technology (NIST) and National Renewable Energy Laboratory (NREL). The thin film samples are synthesized by combinatorial physical vapor deposition (combinatorial sputtering and pulsed laser deposition), and characterized by spatially-resolved techniques for composition, structure, thickness, optical and electrical properties. The results of this study indicate that all these measurement techniques performed at two different laboratories show good qualitative agreement. The quantitative similarities and differences are also discussed using statistical analysis metrics, and lessons learned from this inter-laboratory comparative study are reported.
