Radiant energy (solar energy) plays a vital role due to its continuous power supply and environmentally friendly in meeting the people's energy demand. The need for an endless supply of energy, majorly through solar energy exploitation has driven the expansion and diversification of a device for proper energy storage. This review summarizes a photo-supercapacitor's working mechanism. The classification of a supercapacitor was discussed and the advancements of the active components that makeup a photosupercapacitor and the improvements on photo-supercapacitor in energy storage were highlighted. For the constant generation of electricity, dye-sensitized solar cells (DSSCs) and supercapacitor are incorporated. The invention of hybridized dye-sensitized solar cell (DSSC)-capacitors and DSSC-supercapacitors are crucial in energy storage processes, and the advancement in technology has triggered the creation of a photosupercapacitor for efficient harvesting of energy and proper storage mechanisms. The intent of pairing a DSSC Advanced Materials Science and Technology with a supercapacitor for conversion of energy and proper energy storage arose when dye molecules absorb radiant energy and the absorbed energy is transformed to electrical energy. The use of active components of a photo-supercapacitor will determine its conversion efficiency. The performance of active components of photo-supercapacitors such as dye, electrolyte, photoanode, and the counter electrode are the main factors that contribute to efficient conversion of energy to improve the photo-supercapacitor's storage life.

In recent times, research communities are working on device to harvest solar energy at low cost. Copper‐based quaternary chalcogenides are one among the leading materials in the field. Herein, the electrical and optical performance of quantum well embedded Cu 2 - Fe - Sn - normalS 4 (CFTS) solar cell is investigated in detail. Multiple quantum wells (MQWs) with different bandgaps ensure wider photon absorption of solar spectrum. Hence, MQWs made up of CFTSe/CFTS are incorporated with a variation in well size and well numbers. All the electrical parameters and optical parameters such as power conversion efficiency, quantum efficiency, and its dependence on carrier quantization are discussed in detail. More than 80% external quantum efficiency with just 2 QWs shows the efficient carrier generation and collection of the proposed structure. Device with 10 QWs of size 18/10 nm of CFTSe/CFTS can achieve remarkable efficiency of 21% with good trade‐off between J sc and fill factor.
