The SiO x is utilized as a "passivating" film — an unreactive layer that enhances the stability, reliability and performance of the device. However, that does not mean that just increasing the thickness of this passivating layer will result in improved solar cells.

An efficiency (22.01%) of MoO x -based crystalline silicon solar cells Effective surface passivation is pivotal for achieving high performance in crystalline silicon (c -Si) solar cells. However, many passivation techniques in solar cells involve high temperatures and cost.
In addition, at lower voltages where the effective resistance of the solar cell is high, the impact of a resistance in parallel is large. A silicon oxide film is well known to be a good candidate for a passivation film in a solar cell because it can be used as an insulating film for the PID phenomenon and lower the recombination velocity.
As the passivation decreases, the efficiency dependence on passivation is stronger. The dependence is larger for J0e > 100 fA cm −2 where losses of over 1% absolute are possible. This is a significant loss in efficiency for a solar cell. This shows that effective passivation schemes for both the front and rear of the cell must be implemented.
The gap between large-scale and laboratory-scale results is continuously closing, and very good passivation dielectrics are already possible for the current level of efficiency in solar cells. As other loss mechanisms of the cells are reduced, the surface will require further passivation.
