TL;DR: In this article, a skin solver is implemented in the solar cell simulation software Quokka3 to solve a detailed skin in 1D and to perform the general parameterization.

TL;DR: In this paper, the influence of different thermal post-deposition treatments for the activation of passivating ALD single layers and Al2O3/SiNx stacks was studied, and it was shown that four ALD cycles are sufficient to reach the full potential of surface passivation, and even with one atomic layer of Al 2O3 (one ALD cycle) emitter saturation current densities as low as 45 fA/cm2 can be reached on borondiffused emitters.

TL;DR: In this article, the influence of the firing process and its temperature profile on the degradation behavior of neighboring mc-Si wafers is analyzed with spatially resolved and lifetime calibrated photoluminescence images, normalized defect concentrations N*t are calculated to determine the degradation intensity.

TL;DR: In this article, the corrosion mechanism behind damp heat-induced degradation of screen-printed silver front-side contacts of silicon solar cells due to the presence of acetic acid, which is known to be a decomposition product of the most common module encapsulation material ethylene vinyl acetate, is investigated.

TL;DR: In this paper, a light-induced plating (LIP) method was proposed to improve the efficiency of large area screen-printed silicon solar cells by about 0.3% to 0.4% absolute.
