The p-type Cu2O semiconductor layer is the light harvester component of the photoelectrode and the TiO2 film performs as the capacitive layer. The rationale of the energy scheme shows that the photocharges generated in the Cu2O semiconductor induce lithiation/delithiation processes in the TiO2 film as a function of the applied bias voltage and light power. A photorechargeable lithium button cell drilled on one side recharges with visible white light in ≈9 h in open circuit. It provides an energy density of ≈150 mAh g−1 at 0.1 C discharge current in dark, and the overall efficiency is 0.29%. This work draws a new approach for the photoelectrode role to advance in monolithic rechargeable batteries. info:eu-repo/grantAgreement/ES/DGA/LMP71-21 info:eu-repo/grantAgreement/ES/UZ-DGA/T57-20R info:eu-repo/grantAgreement/ES/MCIU/RYC-2018-025222-I info:eu-repo/grantAgreement/ES/MICINN AEI/EIN2020-112315 info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-107893RB-I00/AEI-10.13039-501100011033 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 13.0 2023 CHEMISTRY, PHYSICAL 19 / 178 = 0.107 2023 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 35 / 439 = 0.08 2023 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 16 / 141 = 0.113 2023 Q1 T1 PHYSICS, CONDENSED MATTER 7 / 79 = 0.089 2023 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 25 / 231 = 0.108 2023 Q1 T1 PHYSICS, APPLIED 13 / 179 = 0.073 2023 Q1 T1 3.348 2023 Biomaterials 2023 Q1 Engineering (miscellaneous) 2023 Q1 Biotechnology 2023 Q1 Nanoscience and Nanotechnology 2023 Q1 Materials Science (miscellaneous) 2023 Q1 Medicine (miscellaneous) 2023 Q1 Chemistry (miscellaneous) 2023 Q1 17.7 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Juarez-Perez, Emilio J.
