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. 000126250 536__ $$9info:eu-repo/grantAgreement/ES/DGA/LMP71-21$$9info:eu-repo/grantAgreement/ES/UZ-DGA/T57-20R$$9info:eu-repo/grantAgreement/ES/MCIU/RYC-2018-025222-I$$9info:eu-repo/grantAgreement/ES/MICINN AEI/EIN2020-112315$$9info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-107893RB-I00/AEI-10.13039-501100011033 000126250 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000126250 590__ $$a13.0$$b2023 000126250 592__ $$a3.348$$b2023 000126250 591__ $$aCHEMISTRY, PHYSICAL$$b19 / 178 = 0.107$$c2023$$dQ1$$eT1 000126250 593__ $$aBiomaterials$$c2023$$dQ1 000126250 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b35 / 438 = 0.08$$c2023$$dQ1$$eT1 000126250 593__ $$aBiotechnology$$c2023$$dQ1 000126250 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b16 / 140 = 0.114$$c2023$$dQ1$$eT1 000126250 593__ $$aChemistry (miscellaneous)$$c2023$$dQ1 000126250 591__ $$aPHYSICS, CONDENSED MATTER$$b7 / 79 = 0.089$$c2023$$dQ1$$eT1 000126250 593__ $$aNanoscience and Nanotechnology$$c2023$$dQ1 000126250 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b23 / 230 = 0.1$$c2023$$dQ1$$eT1 000126250 593__ $$aMaterials Science (miscellaneous)$$c2023$$dQ1 000126250 591__ $$aPHYSICS, APPLIED$$b13 / 179 = 0.073$$c2023$$dQ1$$eT1 000126250 593__ $$aMedicine (miscellaneous)$$c2023$$dQ1 000126250 593__ $$aEngineering (miscellaneous)$$c2023$$dQ1 000126250 594__ $$a17.7$$b2023 000126250 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126250 700__ $$0(orcid)0000-0001-6040-1920$$aJuarez-Perez, Emilio J. 000126250 700__ $$0(orcid)0000-0001-7246-2149$$aHaro, Marta$$uUniversidad de Zaragoza 000126250 7102_ $$12012$$2755$$aUniversidad de Zaragoza$$bDpto.
