Analysis of Enhanced Light Harvesting and Quantum Efficiency in Textured Silicon Solar Cells

TL;DRAbstract

Textures on semiconductor materials, such as monocrystalline and multicrystalline silicon (Si), consist of an array of geometrical structures. The main advantage of such structures is the fact that they are able to significantly increase the amount of transmitted light on the cell surface without the use of other antireflection and light trapping techniques, such as antireflection coatings. Texturing a Si wafer includes three benefits: decrease in external reflection, increase in internal reflection preventing the rays from escaping the solar cell, and increase in effective absorption length due to tilted rays. 
\nThe aim of the thesis is to determine the influence of textures on the total quantum efficiency (QE) of the cell. Firstly, various types of texture structures with different physical parameters, as well as their antireflection and light trapping capabilities are investigated. It becomes evident throughout a brief literature review of textures that regular inverted pyramid
