Metal halide hybrid perovskite solar cells (PSCs) have received considerable attention over the past decade owing to their potential for low-cost, solution-processable, earth-abundant, and high-performance superiority, increasing power conversion efficiencies of up 25.7%. Solar energy into electricity is highly efficient sustainable, but direct utilization, storage, poor diversity are difficult achieve, resulting in a waste resources. Considering its convenience feasibility, converting chemical fuels regarded as promising pathway boosting expanding utilization. In addition, conversion-storage integrated system can efficiently sequentially capture, convert, store electrochemical storage devices. However, comprehensive overview focusing on PSC-self-driven devices with discussion development limitations remains lacking. Here, focus representative configurations emerging PSC-based photo-electrochemical including self-charging packs, unassisted water splitting/CO2 reduction. The advanced progresses this field, configuration design, key parameters, working principles, integration strategies, electrode materials, performance evaluations also summarized. Finally, scientific challenges future perspectives ongoing research field presented.

Porphyrins‐Assisted Cocatalyst Engineering with CoOV Bond in BiVO₄ Photoanode for Efficient Oxygen Evolution Reaction

Abstract The application of photoelectrochemical (PEC) water splitting is limited by the sluggish surface oxygen evolution reaction (OER) kinetics. OER kinetics can be effectively improved through cocatalyst engineering. However, tardy transfer process and serious recombination carriers are key factors restricting development. Taking BiVO 4 as an example, a Co‐modified heme film rich in large conjugated ring structures introduced onto photoanode using solvothermal method. This functions efficient cocatalyst. It considerably reduces overpotential, promotes photogenerated holes, boosts specifically affecting formation OOH*. Simultaneously, formed CoOV bonds induce strong interaction at photoanode/cocatalyst interfaces, reducing carriers. Consequently, onset potential optimized decreases from 0.45 to 0.07 V photocurrent density 1.23 versus reversible hydrogen electrode 5.3 mA cm −2 . work demonstrates facile strategy for designing cocatalysts obtain rapid hole capability reduced carrier PEC performance.
