Solar panels

  1. 1. HISTORY The photovoltaic effect was recognized first in 1839 by the French physicist Edmond Becquerel. Nevertheless, it was not before 1883 the first photovoltaic cell was constructed, for Carlos Fritts, The union is a region of transition between two crown of semiconductors the majority of the semiconductors has connections they write p-n In 1888, the Russian physicist Aleksandr Stoletov constructed the first photoelectric cell based on the photoelectric effect discovered by Heinrich Hertz in 1887. The bell produced the first photovoltaic modern cell in 1954 in the laboratories the Bell. This solar cell was developed by Darii.
  2. 2. As solar panels contribute to life ? The spatial Solar power (in English Solar Space-based power, SSP), term narrowly related to satellite of solar power (in English Solar Power Satellite), is the conversion of solar power acquired in the space in any other type of energy which can be used in space or it is also possible to transmit to the Earth. From the 20th century they have been using photovoltaic panels in the space on board of spatial satellites to produce the electricity necessary for it functioning from the solar light.
  3. 3. Why do you think it´s useful? Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but they can’t usually cover the entire solar range (specifically, ultraviolet, infrared and low or diffused light). Hence much of the incident sun light energy is wasted by solar modules, and they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into different wavelength ranges and direct the beams onto different cells tuned to those ranges This has been projected to be capable of raising efficiency by 50%.
