Photothermal utilization refers to the process of capturing solar energy and converting it into heat through interaction with materials. Currently, the most common solar collection devices include flat-plate collectors, vacuum tube collectors, and focused collectors. These systems are widely used for heating water or air in residential and industrial applications. Solar power is expected to play a major role in large-scale energy production in the future. There are two primary methods for generating electricity from solar energy. The first is the light-to-heat-to-electricity conversion method. This involves using solar collectors to absorb sunlight and convert it into thermal energy, which then heats a working fluid to produce steam. The steam powers a turbine connected to a generator, producing electricity. This process includes both light-to-heat and heat-to-electricity conversions. The second method is direct light-to-electricity conversion, also known as photovoltaic (PV) technology. This approach uses the photovoltaic effect, where sunlight is directly converted into electrical energy by solar cells. Solar panels composed of these cells are commonly used in homes, businesses, and even large-scale solar farms. Photochemical utilization is another form of solar energy use, where solar radiation is employed to directly split water molecules into hydrogen and oxygen. This process, known as water splitting, has great potential for producing clean hydrogen fuel, which can be stored and used later for energy generation. Photobio-utilization involves using solar energy to generate biomass through photosynthesis in plants. This method is one of the oldest and most natural ways of harnessing solar power. Today, it mainly involves cultivating fast-growing trees, oil-producing crops, and large algae. These organisms absorb sunlight, convert it into chemical energy, and store it as biomass, which can be used for fuel or other energy applications.
