A significant number of solar energy devices have been developed because of their abundant supply. However, the performance of single-photovoltaic energy systems is strongly influenced by weather conditions, geographic location, and illumination duration. Therefore, they require support from complementary energy sources within the overall energy system. To address this limitation, integrating a solar cell with a supercapacitor enables direct photo-charging, providing an alternative photo-rechargeable energy solution without generating harmful pollutants. The novel photo-supercapacitor system offers many potential advantages, such as high energy densities, storing harvested solar energy, quick response time, fast charge and discharge rates, a wide operating temperature range, stabilizing power systems, and environmental sustainability. Furthermore, a synergy of photoactive semiconductors and capacitive compounds can be helpful in the fabrication of both stimulus-responsive materials. This allows the photo-generated carrier device to be an effective and ideal renewable energy technology. In this study, we provide a broad overview of the design configuration, working mechanism, and fabrication of various compact system forms of photo-supercapacitor devices. A comparative analysis of innovative materials and electrochemical characterization is specifically explained to evaluate comprehensive energy conversion performance. Herein, this review summarizes all of the advances in photo-supercapacitors for these next-generation energy harvesting and storage, including potential, opportunities, and challenges to build sustainable energy systems as the pioneers of green energy production.</div></div>","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"1083 ","pages":"Article 191670"},"PeriodicalIF":6.7,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149204562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, high-mass-loading electrodes often suffer from slow ion diffusion and inefficient electron conduction, which severely limit their rate capability and practical application. To overcome these limitations, we construct a binder-free three-dimensional (3D) interconnected network on functionalized carbon cloth (FCC) by integrating one-dimensional (1D) carbon nanotubes (CNTs) and two-dimensional (2D) graphene oxide (GO). This architecture serves as a robust scaffold to enable efficient polyaniline (PANI) deposition. Experimental results reveal that 1D CNTs function as conductive interlinks bridging 2D GO nanosheets and the FCC substrate, effectively lowering the charge transfer resistance (&lt;em&gt;R&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ct&lt;/em&gt;&lt;/sub&gt;) and establishing unobstructed transport channels for both electrons and electrolyte ions. Owing to this hierarchical structural design, the electrode achieved an ultrahigh mass loading of 22&lt;!--&gt; &lt;!--&gt;mg⋅cm⁻&lt;sup&gt;2&lt;/sup&gt; after 3600&lt;!--&gt; &lt;!--&gt;s electrodeposition. Electrochemical measurements in a three-electrode configuration delivered a remarkable areal capacitance of 4116 mF⋅cm⁻&lt;sup&gt;2&lt;/sup&gt; at a current density of 5&lt;!--&gt; &lt;!--&gt;mA⋅cm⁻&lt;sup&gt;2&lt;/sup&gt;.
