Customer ServiceBasic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.
However, silicon's abundance, and its domination of the semiconductor manufacturing industry has made it difficult for other materials to compete. An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick.
This shape has a size of 156.75 mm x 156.75 mm (6.17 in x 6.17 in) and has been widely used in the industry for a long time. However, as silicon prices have fallen, manufacturers have found it more profitable to cut the cells into larger and more square shapes, which can cover more area in a panel and generate more electricity.
All silicon solar cells require extremely pure silicon. The manufacture of pure silicon is both expensive and energy intensive. The traditional method of production required 90 kWh of electricity for each kilogram of silicon. Newer methods have been able to reduce this to 15 kWh/kg.
Crystalline silicon solar cells generate approximately 35 mA/cm2 of current, and voltage 550 mV. Its efficiency is above 25 %. Amorphous silicon solar cells generate 15 mA/cm2 density of current and the voltage without connected load is above 800 mV. The efficiency is between 6 and 8% (S. W. Glunz et al. 2006).
After a long period of standardisation on the M2 cell format of 156.75mm, manufacturers cannot agree on a standard size going forward, with each proposing a slightly different format, and of course this means that the finished solar PV modules that the cells are assembled into also differ in size.
