Fig. 4: Overview of techno-economic analysis (TEA) in this study.
From: Single junction CsPbBr3 solar cell coupled with electrolyzer for solar water splitting
a The flow chart of TEA, b cost breakdown of Levelized cost of hydrogen (LCOH), c the result of sensitivity analysis with several technical and economic parameters, and estimated LCOH depending on d solar-to-hydrogen efficiency acquired in this manuscript (STH of 1.7% for gas evolution, 5.0% for operating point reading) and maximum STH for S2 OWS (12%) with assumption of life span of 20 years, and e the life span of the module with assumption that STH of 8.0%. f The result of economic performance comparison in terms of LCOH and ηSTH from refs. 52,45,44,11.
