Concentrators are devices or systems designed to focus or gather energy, typically from sunlight, to enhance efficiency. They are commonly used in solar energy applications, where they collect sunlight and direct it onto a smaller area, such as a solar cell. This process increases the amount of energy produced, making solar power systems more effective. In addition to solar applications, concentrators can also refer to tools used in various scientific fields, such as chemistry and biology, to concentrate solutions or samples. These devices help researchers isolate specific components, facilitating experiments and analyses by providing more concentrated materials for study.
