Scientists introduce c-MOFs in emerging SrZrS₃ chalcogenide perovskites for efficient solar cells

A research led by Dr. Latha Marasamy, a analysis professor on the Autonomous College of Querétaro, Mexico, is setting the stage for developments in solar power know-how. The analysis crew has made a big breakthrough by exploring the capabilities of SrZrS₃ absorbers in cutting-edge chalcogenide perovskite solar cells, marking the primary time such potential has been theoretically predicted.

The combination of SrZrS₃ with conductive metal-organic frameworks (c-MOFs) as gap transport layers (HTLs) has led to spectacular solar cell efficiency.

Using the SCAPS-1D simulation software developed by the College of Ghent, the researchers assessed varied c-MOFs, together with notable candidates like Cu-MOF ({[Cu₂(6-mercapto nicotinate)]·NH₄}n), NTU-9, Fe₂(DSBDC), Sr-MOF ({[Sr(ntca)(H₂O)₂]·H₂O}n), Mn₂(DSBDC), and Cu₃(HHTP)₂. Their efforts culminated in outstanding energy conversion efficiencies (PCEs), with the Cu-MOF-based solar cell reaching an astounding 30.60%.

“These outcomes are groundbreaking,” stated Dr. Aruna-Devi Rasu Chettiar.

The crew ran intensive simulations throughout 193 configurations, highlighting the significance of optimizing essential parameters akin to service focus and layer thickness. This optimization is crucial for enhancing cost service lifetime, diffusion size, and light-weight absorption capabilities.

Additionally they underscored the importance of fine-tuning interfacial properties and minimizing parasitic resistances to attain superior gadget efficiency.

The newly optimized gadgets demonstrated vital enhancements, together with elevated quasi-Fermi ranges, enhanced conductivity, and a outstanding 35% enhance in spectral response in the near-infrared area, stated Dr. Latha Marasamy.

Notably, the gadgets exhibited a excessive recombination resistance of 1.4×10⁷ Ω·cm² and a built-in potential of roughly 0.99 V, additional contributing to their spectacular efficiencies.
