Evolution of Corrosive Potential‐Induced Degradation at the Rear Side of Bifacial Passivated Emitter and Rear Solar Cells
نویسندگان
چکیده
Detrimental corrosive potential‐induced degradation at the rear side of bifacial solar cells has been found recently. This effect is nonreversible and shows typical surface damages in micrometer scale. However, also areas showing no such damage suffer from electrical losses. Cracks nanometer scale underneath surface, that is, interface between Si bulk Al 2 O 3 , turn out to be cause this effect, leading depassivation effects. The emergence these cracks assumed originate oxidation due stress.

Diffusion-based model of local Al back surface field formation for industrial passivated emitter and rear cell solar cells
In this work, the back surface field (BSF) formation of locally alloyed Al paste contacts employed in recent industrial passivated emitter and rear cell solar cell designs is discussed. A predictive model for resulting local BSF thickness and doping profile is proposed that is based on the time dependent Si distribution in the molten Al paste during the firing step. Diffusion of Si in liquid Al...
متن کاملBifacial dye-sensitized solar cells with enhanced rear efficiency and power output.
Pursuing a high power conversion efficiency with no sacrifice of cost-effectiveness has been a persistent objective for dye-sensitized solar cells (DSSCs). One promising solution to this impasse is increased light harvesting. Previous efforts in light harvesting have been made on setting blocking layers or reflecting layers, or adding a light harvester, resulting in tedious procedures without r...

A novel stack passivation scheme, in which plasma silicon nitride (SiN) is stacked on top of a rapid thennal SiO? (RTO) layer, is developed to attain a surface recombination velocity (S) approaching 10 em/s at the L3 O-cm p-typc (l00) silicon surfaee_ Such low S is achieved by the stack cven when the RTO and SiN films "I<ilvldllally yield considerably poorer surface passivation.
