An essential prerequisite for the growth of crystalline silicon from the raw materials is the availability of silicon of the highest purity attainable. 17 Impurities or defects in the single crystals can lower the performance of the solar cell device due to recombination of charge carriers.
The solar cell efficiency of crystalline silicon is limited by three loss mechanisms: optical losses, carrier losses and electrical losses. The back contact silicon solar cell is another high efficiency device, where all the metallisation on the front surface is removed.

3. The principle of a solar cell is same as the photodiode. Explanation: The solar cell works on the same principle as the photodiode, except that no external bias is applied and the junction area is kept much larger. 4.
Interestingly, the much simpler two-terminal device crystalline silicon solar cell was only invented (1953) after the more complex three-terminal crystalline germanium transistor (1947). Both, however, were developed in the famous Bell Telephone Company Research Laboratories (Bell Labs) in New Jersey, USA.
The efficiency, η, is the most commonly used parameter to compare the performance of different solar cells. Pin = 100 mW cm −2 for AM 1.5, A = cell area (cm 2 ). The maximum power point of the cell is the values of I and V ( Imax and Vmax) at which the maximum rectangle in Figure 1.6 meets the I–V curve.
