6 FAQs about [Photovoltaic cell grid line]
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).
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.
Does gridline height affect solar cell conversion efficiency?
Chen et al. [ 4] showed that, for a given number of busbars, the gridline height has a negligible impact on the cell conversion efficiency after it reaches a certain value. This suggests that the aspect ratio of the gridlines should also be optimized to design cost-effective solar cells.
Is gridline segmentation a low-cost pathway to industrial solar cells?
Gridline segmentation combined with an uneven busbar concept is investigated. This is a low-cost pathway to achieving industrial solar cells with energy conversion efficiency above 20% without any additional cost.
Does concentrated sunlight 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).
Do printed gridlines require a uniform gridline profile?
Therefore, printed gridlines require a uniform gridline profile from busbar to busbar, in conjunction with a high aspect ratio. However, in order to obtain cost-effective solar cells, the metallization costs also have to be considered.
