Brief History of Solar cells The history of solar cells goes back to the 19th century. Edmond Becquerel was first to notice the effect of light on a certain molecule; in 1839 he found that two different brass plates immersed in a liquid produced a continuous current when illuminated with sunlight. We now believe that he had made a coppercuprous oxide thin-film solar cell. (Fraas, 2016) this property is called the photoelectric effect, and could be harnessed. An article made by the Union of Concerned Scientist said, “The first photovoltaic (PV) cells, made of selenium, were created in the late 1800s. In the 1950s, scientists at Bell Labs revisited the technology and, using silicon, produced PV cells that could convert four percent of the energy in sunlight directly to electricity.” (How Solar Panels Work, 2015) Nowadays, researchers and scientist are trying to come up with new ways to develop solar cells. Location The recommended location to install the solar system is on top of DOW building. The cause to choosing this location is because it is not close to any trees or building, that will affects the output of the system by shading effect. Figure 1 these pictures taken by me using Google map for DOW building the left from the sky and right side picture was taken from the side How Solar cell Works Solar cells are basically a two element that acts as a semiconductor. However, semiconductors have the property of electron mobility and gap between the energy states
