What are the different types of solar cells?
Solar cells can be constructed in a number of different methods and from different materials. The field of photovoltaics is continuously advancing with new developments and technologies being explored. Solar cells are often catagorized as first, second, or third generation technology. Currently, the world commercial production focuses on first generation solar cells, with a small, but expanding, portion of the market devoted to second generation technology. Third generation photovoltaics are being heavily researched and are primarily found in research labs and satellite/space applications. First generation solar cells: The photovoltaic industry began around crystalline silicon and the first solar cells made using pure crystalline silicon are commonly referred to as first generation. These cells use a single junction and have high efficiencies, but use a large amount of pure crystalline silicon, making the technology relatively expensive. Most of the current market share belongs to firs
