What are the characteristics of industrialized silicon solar cells?
However, existing industrialized silicon solar cells exhibit simple structures. The single crystalline silicon with the Czochralski method or the polycrystalline silicon with the casting method has been adopted on a large scale. Generally, these silicon materials are boron diffusion doped, with a resistivity of 0.5–0.6 Ω cm.
Why do solar cells need crystalline silicon?
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.
What is the basic structure of crystalline silicon solar cells?
Basic structure of crystalline silicon solar cells. The fabrication of crystalline silicon solar cells consists of three main processes, i.e., preparing a junction by diffusion, vapor deposition of an anti-reflection film, and electrode preparation).
How crystalline silicon is a high efficiency solar cell?
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.
Why does a thin silicon wafer affect the yield of a solar cell?
For instance, for the thermal expansion coefficient of the material and the difference in the composition of the slurry, the warping problem of the solar cell is caused, and the thinner silicon wafer exhibits even higher thinness, which is easy to cause debris, and therefore, to affect the yield.
