Is screen-printed aluminum back surface field suitable for p-type Si solar cells?

1. Introduction The screen-printed aluminum back surface field (BSF) formation has been the preferred method in the photovoltaic (PV) industry for the back surface passivation of p-type Si solar cells. Theoretical calculations show that Al-BSF has the potential to provide high-quality back surface passivation .

Can aluminium BSF be used in industrial silicon solar cells?

In this work, we have studied aluminium BSF on industrial silicon solar cells with back parasitic junction. Thickness of the BSF has been measured by SIMS and confronted with the theoretical expected value and simulations.

What is back surface field (BSF) in solar cell recombination?

1. Introduction With the reduction of solar cells thickness, back surface field (BSF) becomes more and more interesting in order to decrease the back surface recombination velocity and to increase collection efficiency.

What is the aluminium-back surface field (al-BSF) cell?

This design (Fig. 1a) is known as the aluminium-back surface field (Al-BSF) cell due to its aluminium use to produce the doped P + region at the back side.

Does aluminum-alloyed back surface field reduce recombination velocity?

Abstract: Screen-printing and rapid thermal annealing have been combined to achieve an aluminum-alloyed back surface field (Al-BSF) that lowers the effective back surface recombination velocity (S/sub eff/) to approximately 200 cm/s for solar cells formed on 2.3 /spl Omega/-cm Si.

What are back-contact solar cells?

This review provides a comprehensive overview of back-contact (BC) solar cells, commencing with the historical context of the inception of the back-contact silicon (BC-Si) solar cells and its progression into various designs such as metallization wrap through, emitter wrap through, and interdigitated configurations.
