6 FAQs about [Width of positive and negative electrodes of solar cell]
How do front electrode patterns affect the performance of solar cells?
The front electrode pattern of the solar cell has an important influence on the performance of the solar cell. This paper proposed an explicit topology optimization method for the design of the front electrode patterns of solar cells. The explicit topology optimization method is based on moving wide Bezier curves with a constrained end.
What is the function of a front electrode in a solar cell?
The front electrode is responsible for collecting the current generated in the semiconductor layer and transmitting it to the current extraction point, and there is a trade-off between the shading loss caused by the front electrode and the series resistance loss of solar cells (Flat and Milnes 1979; van Deelen et al. 2014b ).
Can moving morphable components optimize the front electrode pattern of solar cells?
In order to overcome the above shortcomings, we proposed the moving morphable component (MMC)-based method to optimize the front electrode pattern of solar cells. The MMC-based method uses a set of morphable components to describe the structural topology.
How does the number of components affect the efficiency of solar cells?
It can be seen that the efficiency of the optimized solar cell increases with the increase of the number of components, but the increasing rate of efficiency is slowing down. With the increase of the number of components, the width of the front electrode becomes narrow, which is not friendly to the fabrication of the front electrode.
Does a solar cell have a shading loss?
The grid electrode on the front surface of the traditional silicon solar cell causes shading loss. However, the positive and negative electrodes are placed on the back surface of the interdigitated back contact (IBC) solar cell, which causes no shading loss and improvement of photoelectric conversion efficiency.
What is the initial half-width R of a side-contact solar cell?
The initial half-width r is set to 0.01 times the length of the design domain. Due to the width of the electrode grid is limited by the printing technology, the minimum half-width r of the component in this paper is set to be 25 μm. The four different initial topologies of the side-contact solar cells
