The achievement of optimal performance is a crucial aspect of renewable energy resources. The study attempts to boost the power conversion efficiency of polycrystalline silicon (Si) photovoltaic cells by the application of anti-reflective coating (ARC). The solgel method is employed to synthesize yttrium oxide (Y 2 O 3).
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.
Consequently, an antireflective coating could be applied to the solar cell surface to absorb some of the lost solar energy. The ability of manipulating the pn-junction depth is of great importance as it allows for tuning the solar cell to produce electric energy from the absorption of a desired wavelength.
The application of antireflection coatings (ARCs) on the front of the photovoltaic cell is a prevalent method in the production of silicon photovoltaic cells. The anti-reflective coating augments the photon collection in the solar cell by diminishing the reflection of a bare Si surface (<30 %) to about 10 %.
Liao et al. developed and tested a novel antireflection coating (TiO 2 -SiO 2 /SiO 2 /SiN x) on polysilicon solar cells. The top TiO 2 -SiO 2 layer, which exists in the amorphous state, was prepared with the sol-gel method, and the other two layers were deposited by PECVD.
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.
