Perovskite Tandems Advance Solar Hydrogen Production

Abstract

Benchmark solar to hydrogen conversion efficiency of 18.7% was achieved via photovoltaic cell-electrolyzer system without using well-known expensive III-V-based light absorber. Comparison with previous studies indicates that this efficiency bench is impressive for using less junction (2jn instead of 34jn for III/V), relatively cheap perovskite and silicone solar cell, and high solar electricity to chemical efficiency (74.2%).

Vapor-assisted deposition of highly efficient, stable black-phase FAPbI 3 perovskite solar cells

“…However, vapor-treated FAPbI3 films showed stronger absorption over all wavelengths compared to the reference sample, which was in accord with the enhanced phase purity and crystallinity apparent from the XRD results. Unlike this work, other recent studies that used MACl as an additive (5,32,33), a considerable amount of MA was doped inside the bulk FAPbI3. Our UV-vis absorption and PL emission matched the features of pure FAPbI3, unlike the results in ( 5) and ( 32), where the features were blue-shifted.…”

Perovskite/Si tandem solar cells: Fundamentals, advances, challenges, and novel applications

“…As comment by Kim et al., this work is definitely a milestone in deployment of photovoltaic‐electrochemical (PV‐EC) system for solar hydrogen production, but more efforts should be made to further optimize both the tandem cell and electrochemistry cell for boosting the overall device performance. In addition, upscaling the PV‐EC system, enhancing its life‐span, and techno‐economic analysis should be done to bring such technology into next step 127 . Another approach to combine perovskite/Si tandem cell with electrochemistry cell is developing solar flow battery.…”

Halide perovskite photovoltaic-electrocatalysis for solar fuel generation

“…One particularly interesting application of halide perovskites is PV-EC fuel generation since it is possible to provide customized photovoltage for the electrochemical reaction depending on the configuration of the tandem solar cell. 8–10…”
