Photosupercapacitors are emerging with promising prospects for advanced applications such as wearables and IoT devices. Solar-driven systems capable of both harvesting and storing energy are increasingly viewed as practical and sustainable alternatives on a global scale. Incorporating self-charging energy units can play a transformative role in rural electrification by providing affordable and reliable power to areas where traditional electrification methods are ineffective or inaccessible. Depending on the solar cell part integrated with the supercapacitors, the photosupercapacitors can be classified as different types. In this review, we shall discuss about the most prominently reported ones based on perovskite and dye-sensitized solar cells (DSSCs).
