This document discusses solar energy and related careers. It begins by defining a solar panel as a material that produces electricity directly from light. It then discusses different types of scientists that work with solar energy, such as bioengineers, astronomers, and chemical engineers. Chemical engineers specifically work with the chemical processes that occur in solar panels to produce electricity. The document also addresses when and where solar energy works best, noting that solar panels collect most energy during the day and that solar energy was first used in France in 1839. In the end, it provides more details about pursuing a career as a chemical engineer working with solar energy.
