One of the primary components in solar photothermal collectors is the absorber because its role is very influential on system performance. Recent research on developing solar photothermal absorbents has found materials with impressive absorption performance of more than 90%. The next challenge is to find environmentally friendly materials, simple and easy to manufacture, available in abundance, easy to recycle, easy to install, durable, and easy to maintain while maintaining high performance. In addition, the existing solar thermal collector is varied and requires selecting appropriate materials. Therefore, this study presents a brief review to make it easier for engineers to choose the most suitable material for solar thermal application, which is designed based on the latest research findings. Moreover, this study is also helpful for researchers as a reference source to find novelty and state-of-the-art research on photothermal absorber materials.
