Abstract: Photovoltaic (PV) systems, which directly convert solar light into electricity, are one of the most attractive renewable energy sources to fulfill the increased demand for clean energy. The accumulated installation of PV systems has expanded rapidly, reaching over 700 GW in 2020. Although black colored PVs maximize energy generation by harvesting a broad range of solar light, their monotonous color limits their installation in urban areas and portable devices where the harmonization of color with neighboring exterior elements is a high priority. Moreover, it is not suitable for covering transparent area of buildings, such as window and curtain wall. Hence, the demand for aesthetic PV systems is increasing significantly. In this review, we focus on the current status of colored PV systems and their prospects for aesthetic energy harvesting system. This work reviews possible approaches to realize colored PV systems by implementing semitransparent cells, selective reflective films, and luminophores. Additionally, the research progress to minimize light sacrifice for color production has been investigated. Moreover, the technical limitations of each technology for colored PV systems are presented in terms of color purity and efficiency. Finally, obstacles to commercialization and their solutions are discussed. Therefore, this study provides a crucial review of the latest developments and current status in the field of colored PV systems.
