Energy-level matchingThe development of highly efficient electron transport layer free perovskite solar cells (ETL-free PSCs) with simplified and economical device configurations can significantly motivate the commercialization of PSCs. However, the performance of ETL-free PSCs has been hampered by the...

(Jph,pero,Jph,Si), which is a well-suited optimization function for monolithic tandem solar cells, as it directly accounts for current matching60. The individual simulations were performed with the FEM solver JCMsuite61for a 300–1,190 nm wavelength range and produced absorption spectra for ...
20. Furthermore, the matching of τlow f for devices with and without negative capacitance is strong evidence for the fact that both processes are of the same origin as already hypothesized in ref. 10. Analysis in the time domain To better illustrate the meaning of these time constants, ...
the quasi-EFof WBG perovskite is counterbalanced. The relatively larger energy gap between perovskite and charge transport layers (CTLs) would arise energy loss and interfacial non-radiative charge recombination [59]. Therefore, desirable energy level matching between perovskite and CTLs is essential ...
Moreover, PbS improves energy‐level alignment and lattice matching at the interface, enhancing device performance. With this bridging effect of PbS, a wide‐bandgap (1.68 eV) n–i–p single‐junction perovskite solar cell achieved a PCE of 20.39% and an open‐circuit vol...
We have identified several important factors of the HTMs for efficient PSCs, including high uniformity of the HTM capping layer, perovskite-HTM energy level matching, good HTM solubility, and high conductivity. These factors affect interfacial hole injection, hole transport, and charge recombination ...
