6 FAQs about [Solar cell front grid line structure]

What are the front grid designs of solar cells?

The front grid designs of the above-mentioned solar cells consist patterns on busbars. There are some hollow structures in the busbars in Cell 1, Cell 2, and Cell 4 and some rectangular shaped openings in the busbar in Cell 3. Due to these patterns on the busbars the area consumed by the busbars are less which corresponds to less shading losses.

How does solar cell performance depend on the front contact grid design?

Solar cell performance is highly dependent upon the front contact grid design for minimizing the power losses due to shading (optical loss) and for proper collection of the photo-generated charge carriers (electrical loss).

Do metal grid lines affect grid contact design in concentrator solar cells?

L. Wen et al. had studied the optimization of design for the two-grid structure in concentrator solar cells (2010). The influence of metal grid lines and power loses under concentrated sunlight in the optimization of grid contact design has been shown by Lee and Rao (2016). M. S.

What is the optimum design for the front grid?

Thus an optimum design for the front grid is required considering the width and layout of the fingers and bus bars.

How to design a front grid?

Front grid design can be made either in modelling method based on the equations (Goetzberger et al., 1998, Cuevas and Russell, 2000, Mette, 2007) or by simulation method using software like SENTAURUS, SPICE and ray tracing (Yang et al., 2012).
