“…Also, it is interesting to note that the IPCE also increases substantially for the device with optimal GNR concentration (∼80%) compared to the architecture without GNR (∼35%). GNR is reported to enhance light absorption, charge injection, and collection in the TiO 2 systems and it proportionally increases with an increase in GNR concentration . The enhanced features observed are attributed to GNR strips that could cause electrons to move through the TiO 2 nanoparticles, which are interconnected by GNR channels, creating uninterrupted electron flow.…”

“…An efficient ETL can prevent major damage of intrinsic charge recombination taking place within the AgBiS 2 NCs. 64 Also, the effective transport of excited electrons to the transparent conductive materials reduces recombination losses taking place between the ETL and oxidised species in the absorber and electrolyte. It should be noted that there should be a favourable alignment of the energy levels of these charge transport layers with that of NCs for efficient charge carrier dynamics, as shown Fig.…”

“…One can see several reports on ETL modifications to enhance charge extraction from the photoabsorber to ETL to improve the device performance. ,, Creating an ETL with suitable band structures can lead to energy level optimization and favorable alignment for optimal charge extraction, reduced interfacial and surface recombination of charge carriers, and uninterrupted charge transport in the device. However, the energy level alignment is highly dependent upon the energy level positions of the adjacent interface layers, where it enables a proper built-in potential and favors a high charge transportation in solar cells …”

“…15 In the conventional AgBiS 2 device, deposited via the successive ionic layer adsorption and reaction (SILAR) method, mesoporous TiO 2 is often used as the ETL, which transfers the generated carriers from the photosensitizer (QDs) to the conductive substrate. 16 There are reports on the usage of ZnO and SnO 2 as ETLs for AgBiS 2 -based devices, which offer appropriate band alignments in the system, enabling efficient charge carrier dynamics across the interfaces. Also, several modifications on these ETLs reflected in boosting the device performance of AgBiS 2 .…”
