Solar cell electrode pattern

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.

Can a solar cell have a divided electrode structure?

Fabrication of solar cells with a divided electrode structure A screen printing process was used for metallization, and a 6-inch multicrystalline blue wafer without electrodes was used. A multicrystalline silicon solar cell with an electrode pattern for division was fabricated to verify the simulation results.

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 ).

What is a front electrode pattern?

The front electrode pattern is composed of a set of wide Bezier curves. The control points and width of the wide Bezier curve are regarded as design variables. The validity of the proposed method is tested on side-contact and pin-up module solar cells.

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 to metallize a solar cell?

In the metallization step, the electrode pattern was printed on a wafer by using a mesh mask and a screen printer. The front electrode of the solar cell was dried at 265 °C for 30 s to remove the solvent after printing, and the rear electrode was also then processed in the same manner.
