Alireza Ghoorchian Integrated Science, 214 – Sec. B Instructor: Virginia Harper What new techniques are being developed to harness the energy of the sun? Solar power is produced by collecting sunlight and converting it into electricity, This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is most often used in remote locations, although it is becoming more popular in urban areas as well. This article explores advances in solar energy technology. Since first discovered in the 1860s, the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells, the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses, but is still too expensive and risky for many residents. Researchers are still making advances to solar technology for it to be a feasible energy source in the future. Solar energy was first started in the 1860s when Auguste Mouchout and William Adams found a way for storing solar radiation into tanks of water. Since then, there have been improvements to the processing of solar energy, which has been split into two categories: agricultural based and electricity based. The agricultural method, otherwise known as thermal solar energy, uses the sunlight

to heat liquid and power steam engines. Solar collectors can be used on houses or business buildings to store the energy. Different types of solar collectors are flat-plate collectors, evacuated tube collectors and integral collector storage systems. The electrochemical process is more complicated and requires photovoltaic (PV) cells to capture the solar energy and convert it into electricity. PV cells have many uses, including powering batteries or mechanical devices by absorbing the photons and creating a voltage. Silicon in the PV conductors absorbs photons, but sometimes impurities are
