Advantage And Disadvantage Of Solar Cells

Photovoltaic (PV) cells are a great way to produce energy from the sun. A photovoltaic cell is a semiconductor that converts light into a direct current. This energy can be used in calculators, homes, street signs, stop lights, and many more everyday products. In 1839, Antoine-César Becquerel discovered the photovoltaic effect. The photovoltaic effect is when light falls on an electrode, producing voltage. Following Becquerel’s discovery Charles Fritts constructed an ultrathin semiconductor of gold in order to produce a current. Charles Fritts method was very inefficient because it only converted less than 1% of the light intake to electricity. Even though gold semiconductors is inefficient in today's technology it was a foreshadowing of a new renewable source of energy. In 1927, copper oxide was used as a semiconductor while copper was used for the casing of the semiconductor. This new material still only converted less than 1% of the light intake into voltage. In 1941 the inefficiency problem was helped by Russell Ohl, who created the silicon solar cell. The use of the silicon solar cell proved to be more productive as it raised converted 6% of light intake. In 1980, solar cells fabricated out of…show more content…
For each kw of installed capacity for PV cells the price ranges from $ 1700-2500. This disadvantage does not help the people who need a cheap energy source, because it will be too expensive to buy. Also they are highly inefficient because the good solar panels will only convert up to 45% of the light intake into energy. This means that in order to increase productivity you will need to install large areas of PV panels, which means spending more money. Another aspect that makes them inefficient is that they won't function during the night because they need direct sunlight to convert energy. Even though they cost little money for maintenance the PV panels are still very fragile and can be broken very
