Diode Laser‐Crystallization for the Formation of Passivating Contacts for Solar Cells

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 16, Issue 5, May 2022., 2022
A new method of laser treatment of passivated contacts for wafer solar cell application was investigated. The Czochralski wafer samples were deposited with highly doped amorphous silicon layers on both sides. The samples are scanned with two different speeds and the corresponding power densities.

Investigation of the Defect Distribution of Laser Contact Opening Applied to Poly‐Si/SiNx Stacks

open access: yesphysica status solidi (a), Volume 219, Issue 8, April 2022., 2022
For poly‐Si contact schemes, an intact interfacial oxide is crucial. Using a tetramethylammonium hydroxide (TMAH) etch, the defects in the oxide due to laser ablation of SiNx on poly‐Si are magnified. The defect density is significantly increased in areas where adjacent laser pulses overlap.

Evolution of Corrosive Potential‐Induced Degradation at the Rear Side of Bifacial Passivated Emitter and Rear Solar Cells

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 16, Issue 2, February 2022., 2022
Potential‐induced degradation is a severe reliability problem for photovoltaic cells and modules. A corrosive potential‐induced degradation mechanism at the rear side of bifacial solar cells is investigated. This potential‐induced degradation effect is nonreversible and shows typical surface and subsurface damages on the micrometer scale, which are ...
