Upgrade the Efficiency of Thin AlGaAs Based Hetero-Junction Silicon Solar Cells Through Thickness Profile Optimization

This work uses PC1D simulation software to demonstrate the design and analysis of a thin-crystalline silicon (c-Si) and AlGaAs based hetero-junction solar cell. Solar energy has steadily gained popularity recently among all renewable energy sources. Although there are many kinds of solar energy technologies available, such as concentrated solar power and solar thermal, solar photovoltaic (PV) is the most popular and extensively used type. Increasing the solar cell's efficiency is therefore essential to establishing photovoltaic technology as a primary energy source. So, one of the best ways to achieve high efficiency is to use hetero-junction solar cells with appropriate band gap matching to improve open circuit voltage and integrated photon electron generating in a wide area of the spectrum. In order to achieve 19.9% device efficiency, the doping profile and material depth of Si-AlGaAs based heterojunction solar cells are optimized in this work. Before building a physical prototype, we may use PC1D software to design and evaluate the solar cells' performance in a simulated environment. This can help us save time and money.
