Unlocking the full potential of passivating contacts, increasingly popular in the silicon solar cell industry, requires determining the minority carrier lifetime. Minor passivation drops limit the functioning of solar cells; however, they are not detected in devices with open-circuit voltages below 700 mV. In this work, simulations and experiments were used to show the effect of localized surface defects on the overall device performance. Although the defects did not significantly affect…

Carrier-selective contacts for Si solar cells
Carrier-selective contacts (i.e., minority carrier mirrors) are one of the last remaining obstacles to approaching the theoretical efficiency limit of silicon solar cells. In the 1980s, it was
