A typical single crystal silicon PV c ell of 100 can produce a b out 1.5 watts of power at 0.5 volts DC and 3 amps under full sunlight (1000 ). The power output of the cell is directly propo rtional to the inten sity of the su nlight.
The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900°C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC.
Silicon solar cells are the most broadly utilized of all solar cell due to their high photo-conversion efficiency even as single junction photovoltaic devices. Besides, the high relative abundance of silicon drives their preference in the PV landscape.
As one of the PV technologies with a long standing development history, the record efficiency of silicon solar cells at lab scale already exceeded 24% from about 20 years ago (Zhao et al., 1998).
The word Photovoltaic is a combination of the Greek Work for light and the name of the physicist Allesandro Volta. It refers to the direct conversion of sunlight into electrical energy by means of solar cells. So very simply, a photovoltaic (PV) cell is a solar cell that produces usable electrical energy.
The first chapter includes a review of the history, the present status of photovoltaic materials. The second chapter contains the review of semiconductors and their properties, and gives a comparison among semiconductors and insulators in terms of their energy band structures.
