Efficient　solar-driven　production　of　fuels　and　electricity　is　significant　for　achieving　a　decarbonized　society.　However,　the　existing　systems　still　suffer　from　drawbacks　including　limited　photovoltaic　(PV)　efficiency　under　high　temperatures　and　large　irreversibility　in　solar-to-thermal　conversion.　In　this　research,　a　novel　system　involving　the　integration　of　PV　modules　and　membrane　reactor　via　spectral　splitting　technology　is　proposed　to　cogenerate　fuels　and　electricity　with　improved　efficiency.　The　sunlight　with　suitable　wavelengths　for　the　PV　power　generation　is　directed　on　the　PV　module,　and　the　residual　part　is　concentrated　on　a　membrane　reactor　for　solar　fuels　production　via　dry　reforming　of　methane　(DRM).　Instead　of　generating　waste　heat　in　PV　system,　the　thermal　energy　from　sunlight　can　be　utilized　by　thermochemical　reactions　and　stored　in　solar　fuels,　leading　to　a　decline　of　the　PV　temperature　and　enhanced　PV　efficiency.　Based　on　membrane　reactors,　the　equilibrium　of　DRM　shifts　forward　for　achieving　a　high　methane　conversion　at　a　relatively　low　temperature.　This　system　can　deliver　75%　of　energy　efficiency,　34%　of　solar-to-electric　efficiency,　and　71%　of　exergy　efficiency.　Additionally,　the　carbon　dioxide　reduction　rate　(CDRR)　could　reach　514.5　kg　m−2　year−1.　Our　findings　provide　insights　into　high-efficient　solar　energy　utilization　involving　membrane　reactors.　©　2022　Elsevier　Ltd
