Basic polycrystalline silicon based solar cells with a total area efficiency of app. 5% has been fabricated without the involvement of anti-reflecting coating. This is a resonable result considering that comercial high efficiency solar cells have a con-version efficiency of about 22%, as outlined in chapter 1.
Polycrystalline silicon is a multicrystalline form of silicon with high purity and used to make solar photovoltaic cells. How are polycrystalline silicon cells produced?
The technology is non-polluting and can rather easily be implemented at sites where the power demand is needed. Based on this, a method for fabricating polycrystalline silicon solar cells is sought and a thorough examination of the mechanisms of converting solar energy into elec-trical energy is examined.
Cells 92 (4) (2008) 418–424, Copyright (2008), with permission from Elsevier. Si played a vital role in the fabrication of polycrystalline cells until 1997. Silicon was needed for many applications such as microelectronic devices and PV devices, and the cost is very important to design PV devices.
A maximum efficiency of 5% was achieved for a fabricated polycrystallin silicon solar cell using spin-on phos-phorus as dopant, sample O8 in table B.2. Using screen printing phosphorus paste a maximum efficiency was achieved at 4%.
The monocrystalline silicon solar cells are quite costly and there is little room for a price reduction due to the high price of monocrystalline silicon materials and the complex cell manufacturing process [ 23 ]. As a result, in industrial production, polysilicon has replaced monocrystalline silicon.
