The solar cell has many uses and is used for example also for charging smartphones, tablets, and laptops.Ī solar cell is a type of photo diode. As prices have dropped, the market has grown by an average of 40% since 2000 and by the end of 2011, there were approximately 64 GW of PV capacity installed in the world, of which 98% consisted of facilities connected to various national electricity systems.
The price of solar cells has, however, dropped sharply between 20 as a result of advances in technology and the expansion of production capacity in the world. polycrystalline or multi-crystalline cells Ĭollege students writing there research paper on the topic have to learn that solar cells have historically been expensive and have mostly been used in places not reached by the grid, such as summer houses, satellites, and lighthouses.The crystalline cells can also be divided into two types: We can write a Custom Research Paper about Solar Cells for you! They consist of silicon that has been doped with various substances for desired functioning. solar panels with crystalline solar cells Ĭrystalline cells are most prevalent today as they have a higher efficiency than thin film cells.One can generally divide the solar panels into two groups: One can also connect in parallel solar cells in order to increase the current.
Technical research paper example solarcell series#
Each individual cell generates a relatively low voltage therefore there are series of the solar cells connected in solar panels. When these diodes are illuminated, an electrical current goes in the diode reverse direction. A solar cell or photovoltaic cell is a device comprising semiconductor (usually silicon) functioning as diodes.
