The transition metals alone are the largest group, but alkali metals, alkali earth metals and rare earth metals are all metals too. And then of course there are the normal metals to the right of the transition metals.

WhatsApp: +86 18221755073Antimony sulfide (Sb2S3) is a promising candidate as an absorber layer for single-junction solar cells and the top subcell in tandem solar cells. However, the power conversion efficiency of Sb2S3-based solar cells has remained stagnant over the past decade, largely due to trap-assisted non-radiative recombination. Here we assess the trap-limited conversion …
