The aim of this study is to investigate the shading effect on an architecture of a photovoltaic generator (PVG) proposed in our previous research work. This architecture consists of three PV modules in series connected. Two of them consist of amorphous silicon cells in series connected. This architecture is conceived as a PV concentrator, where the two amorphous PV modules are located in the lower positions, left and right. The third PV module is located in the upper position precisely in the focus. The role of the upper PV module is to absorb the solar rays which are reflected by the two other PV modules to gain the maximum solar energy. This architecture is aimed at solving the problems existing with the architecture of tandem solar cells proposed in the literature. These problems are the mismatch between cells and the tunnel junction costs and fabrication. In this chapter, we use MATLAB/SIMULINK for modeling this architecture and studying its characteristics (P–V and I–V) in case of partial shading. Through this study, it was found that the maximum of the power provided by the proposed PVG is influenced by the partial shading. To solve this problem we can make this proposed PVG architecture as a solar tracker.

摘要

The aim of this study is to investigate the shading effect on an architecture of a photovoltaic generator (PVG) proposed in our previous research work. This architecture consists of three PV modules in series connected. Two of them consist of amorphous silicon cells in series connected. This architecture is conceived as a PV concentrator, where the two amorphous PV modules are located in the lower positions, left and right. The third PV module is located in the upper position precisely in the focus. The role of the upper PV module is to absorb the solar rays which are reflected by the two other PV modules to gain the maximum solar energy. This architecture is aimed at solving the problems existing with the architecture of tandem solar cells proposed in the literature. These problems are the mismatch between cells and the tunnel junction costs and fabrication. In this chapter, we use MATLAB/SIMULINK for modeling this architecture and studying its characteristics (P–V and I–V) in case of partial shading. Through this study, it was found that the maximum of the power provided by the proposed PVG is influenced by the partial shading. To solve this problem we can make this proposed PVG architecture as a solar tracker.
