Understanding Auger recombination in perovskite solar cells

Abstract

Enhanced radiative efficiency, long carrier lifetimes, and high carrier mobilities are hallmarks of perovskite solar cells. Considering this, complete cells experience large nonradiative recombination losses that restrict their VOC considerably...

Harnessing the potential of CsPbBr3-based perovskite solar cells using efficient charge transport materials and global optimization

“…[6][7][8] Among the various types of PV solar cells, thin lm solar cells (TFSCs) have gained widespread consideration due to their fast growth and potential for high performance. [9][10][11][12][13][14] However, the efficiency of TFSCs is strongly inuenced by the choice of semiconductor materials and growth methods employed. Despite incremental gains in efficiency since the invention of the rst modern silicon solar cell in 1954, signicant progress has been made, with modules developed by 2010 capable of converting up to 18% of solar energy into electricity.…”

Achieving above 24% efficiency with non-toxic CsSnI3 perovskite solar cells by harnessing the potential of the absorber and charge transport layers

“…Among the various types of solar cells, perovskite solar cells (PSCs) have become predominant for their ideal tunable bandgaps, long diffusion length, better carrier transfer and ease of fabrication. 3–9 It has also been noticed in recent studies that MAPbI 3 is conventionally used in perovskite solar cells since its introduction in 2009 by Kojima et al 10 Extensive research also confirms that lead (Pb)-based PSCs have higher efficiencies than those based on Pb-free perovskites. 11,12 Despite the advantage of efficiency, the toxicity of Pb and environmental issues are always a concern while using these perovskites.…”

Design Insights into La2NiMnO6-Based Perovskite Solar Cells Employing Different Charge Transport Layers: DFT and SCAPS-1D Frameworks

“…The SCAPS-1D simulator is utilized to compute the PV parameters of the investigated PSCs using the fundamental equations of semiconductor physics namely Poisson’s equation (eq ) and the continuity equations for both the carriers (electrons and holes) (eqs and ). − The simulation code also takes into account the loss mechanisms in the form of the Shockley–Read–Hall (SRH) recombination , for the computation of the PV parameters.
