The development of solar cell technology began in 1839 the search for the French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect during experimentation with a solid electrode in an electrolyte solution when he saw that a voltage developed when the light fell on the electrode. The main events are discussed briefly below, and other milestones can be accessed by clicking on the image shown below.
Charles Fritts – First Solar Cell: the first real solar cell was built around 1883 by Charles Fritts, who used selenium-coated seams (a semiconductor) with an extremely thin gold layer. The device only had 1% efficiency.
Albert Einstein – Photoelectric effect: Albert Einstein explained the photoelectric effect in 1905 for which he received the Nobel Prize for Physics in 1921.Russell Ohl – Silicon solar cell: the first solar cells, however, had an energy conversion efficiency of less than one percent. In 1941, the silicon solar cell was invented by Russell Ohl. Gerald Pearson, Calvin Fuller and Daryl Chapin (efficient solar cells) In 1954, three American researchers, Gerald Pearson, Calvin Fuller and Daryl Chapin, created a silicon solar cell capable of efficient six percent direct sun power conversion. They created the first solar panels. Bell Laboratories of New York announced the production of the protocol type of a new solar battery. Bell had financed the survey.
The photovoltaic cell or photoelectric cell (solar cell) is a solid-state electrical device that converts light energy directly into electricity through the photovoltaic effect. The energy of light is transmitted by photons, small packets or quanta of light. The electrical energy is stored in electromagnetic fields, which in turn can make a flow of electrons flow. Solar cell assemblies are used to make solar modules that are used to capture energy from sunlight. When multiple modules (as before installation in a pole-mounted tracking system), the resulting integrated group of modules, all oriented in a plane, called the solar panel are assembled.
The electrical energy generated by solar modules is an example of solar energy. Photovoltaics is the field of technology and research related to the practical application of photovoltaic cells to produce electricity from light, even if often used specifically to indicate the generation of electricity from sunlight. Cells are described as photovoltaic cells when the light source is not necessarily sunlight. These are used to detect the electromagnetic radiation of light or other near visible field, for example, infrared detectors or by measuring the intensity of light.
