New webinar! Application of SIMS in Solar PV Research: The Role of Hydrogen in Crystalline Silicon Solar Cells

Friday, January 14, 2022

Phosphorus-doped polysilicon (poly-Si)/SiOx passivating contacts can dramatically reduce carrier recombination at the interface between metal contacts and silicon, achieving an excellent surface passivation, thus allowing high solar cell efficiencies. It has been widely reported that the in-diffusion of hydrogen in the poly-Si passivating contacts can further improve the passivation quality. Secondary Ion Mass Spectrometry is used to investigate the correlation between the hydrogen amount in the poly-Si/SiOx structure and the surface passivation level.

In this webinar, Dr Di Kang will present results suggesting that, to achieve the highest passivation quality, an optimum amount of hydrogen surrounding the interfacial SiOx is needed, while insufficient or excess hydrogen can both lead to degradation of poly-Si passivation.
