Metal halide hybrid perovskites solar cell (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 to 25.7%. Solar energy conversion into electricity is highly efficient and sustainable, but direct utilisation, storage, and poor energy diversity are difficult to achieve, resulting in a potential waste of resources. Considering its convenience and feasibility, converting solar energy into chemical fuels is regarded as a promising pathway for boosting energy diversity and expanding its utilisation. In addition, the energy conversion‐storage integrated system can efficiently sequentially capture, convert, and store energy in electrochemical energy storage devices. However, a comprehensive overview focusing on PSC‐self‐driven integrated devices with a discussion of their development and limitations remains lacking. In this review, we focus on the development of representative configurations of emerging PSCs‐based photo‐electrochemical devices including self‐charging power packs, unassisted solar water splitting/CO2 reduction. We also summarise the advanced progress in this field, including configuration design, key parameters, working principles, integration strategies, electrode materials, and their performance evaluations. Finally, scientific challenges and future perspectives for ongoing research in this field are presented.This article is protected by copyright. All rights reserved

“…46 Apart from its utilization as a photoelectrode, Si is also an excellent material for photovoltaics and Si solar panels are favored in PV-EC systems for CO 2 reduction. 47,48 To achieve a high STF conversion efficiency, the Si photovoltaic cell can be connected in series to drive electrochemical CO 2 reduction. Thus, the further development of Si as a photo-absorber will be broad due to its attractive properties.…”

“…By coupling with PV, an EC system consisting of copper electrocatalysts is also utilized to efficiently reduce CO 2 for C 2+ value-added hydrocarbons. Si (series) solar cells, [108] dye-sensitized solar cell (DSSC) solar cells, [109] copper-indium-galium-sellenide (CIGS) solar cells, [110] and perovskite solar cells [111] are some of the solar cell types that are used to provide insufficient energy to PV-integrated EC systems using copper-based electrocatalysts as a cathode. [112] However, the conversion efficiency to C 2+ using a copper still faces limitations compared to C 1 selectivity of over 90%.…”

The realization of a complete techno-economy through a significant carbon dioxide (CO2) reduction in the atmosphere has been explored in various ways. CO2 reduction reactions (CO2RRs) can be induced using sustainable energy, including electric and solar energy, using systems such as electrochemical (EC) CO2RR and photoelectrochemical (PEC) systems. This study summarizes various fabrication strategies for non-noble metal, copper-based, and metal-organic framework-based catalysts with excellent FE for target carbon compounds, and for noble metals with low overvoltages. Even though EC and PEC systems exhibit high energy-conversion efficiency using excellent catalysts, they are not completely bias-free operations because they require external power. Therefore, photovoltaics, which can overcome the limitations of these systems, have been introduced. The utilization of silicon and perovskite solar cells for photovaltaics-assisted EC (PV-EC) and photovaltaics-assisted PEC (PV-PEC) CO2RR systems are cost efficient, and the III-V semiconductor photoabsorbers achieved high solar-to-carbon efficiency. This review focuses on all the members composed of PV-EC and PV-PEC CO2RR systems and then summarizes the special cell configurations, including the tandem and stacked structures. Moreover, current problems such as a low energy conversion rate, expensive PV, theoretical limitations, and scale-up to industrialization are discussed with the suggested direction.
