This is a zipped file containing research data supporting the publication "Identifying Current Collectors That Enable Light-Battery Interactions", published in Small Methods. The datasets are organized by figure. UV vis data was collected in a Perkin-Elmer Lambda 750 in transmission mode, with the spectra smoothened by a Savitzky–Golay filter prior to plotting. LSV scans were carried out in a Biologic VMP-3 potentiostat using Zn/Li metal as a counter/reference electrode at a scan rate of 5mVs-1. Python code for plotting the LSV curves and transmission data is provided. All electrochemical cycling data was carried out on a Biologic BCS-800 potentiostat, at different current densities (24, 60, 120, 240 mA/g) and long-term cycling at 100 mA/g. Cells were run in triplicates with the mean value and standard deviation shown in the manuscript. The mass loading was 4-4.3 mg/cm2.
