“…Ahmed et al, in order to boost the absorption spectrum of the MAPbI 3 at its band edges without complicating the cell configuration, by introducing nanoparticles for example, or the thickness of the active layer, suggested the use of an ETL nanocomposite build by MoS 2 nanosheets (few monolayers and a monolayer) impeded within the TiO 2 layer. The utilization of the MoS 2 (that demonstrated energy bandgaps from 1.3 to 1.9 eV, depending on the number of the layers) into the ETL succeeded to extend the absorption spectrum of the device from 350 to 800 nm (see Figure d).…”

In this Research News, the authors summarize the work that has been done on the utilization of 2D materials beyond graphene in the electron transport layer (ETL) and hole transport layer (HTL) selected of metal halide perovskite solar cells (PSCs). On the one hand, the impact of such materials in the stability of PSCs under operational conditions is impressive. Stabilities for encapsulated PSCs cells under illumination and ambient conditions at maximum power point that retain 80% of their initial performance (T80) have been reported. On the other hand, the extraction of photogenerated holes has been reduced to few microsecond when a 2D material–based HTL or ETL is introduced. The faster photogenerated charge extraction lowered the recombination rates and resulted in higher power conversion efficiencies. The most interesting thing is that the 2D materials have been successfully applied for large active area cells (≈1.05 cm2) as well. The exploitation of 2D materials, beyond graphene, is a very interesting and promising technology that shows a high potential pathway towards the envisioned future commercialization of PSCs through addressing their performance, stability, and scalability priorities.

“…7 The best reported efficiency of MoS 2 as the electron transport layer in a perovskite solar cell is ∼4.43%. 8 A new Janus TMDs configuration, i.e., MoSSe monolayer (ML), is recently synthesized by sulfurization/selenization of the MoSe 2 /MoS 2 monolayer. This Janus MoSSe monolayer does not possess the inversion symmetry because of two different chalcogens.…”

Heterostructure AZO/WSeTe/W(S/Se)₂ as an Efficient Single Junction Solar Cell with Ultrathin Janus WSeTe Buffer Layer

Transition metal dichalcogenides based materials exhibit promising optoelectronic properties for solar cell application. We considered the heterostructure single junction solar cell with bulk W(S/Se)2 as an absorber material and ultrathin Janus WSeTe layer as a buffer layer. The optoelectronic properties of WSeTe monolayer are calculated using density functional theory calculations. The high absorption coefficient of WS2/WSe2 makes them suitable absorber materials. The performance of layered single junction heterostructure is simulated using SCAPS-1D simulator. The device performance is evaluated to understand the effect of an absorber layer thickness, carrier concentration, defect density, work function, buffer layer carrier concentration, and interface defect density. After optimization of all the possible parameters, the maximum efficiencies noted are 18.87% and 18.1% for AZO/WSeTe/WS2 and AZO/WSeTe/WSe2 solar cells, respectively.

“…One of the main issues that hinder the development of perovskite solar cells is poor stability. − To overcome the difficulty, numerous efforts were devoted to improve the interface of the device, including developing various new electron transport materials (ETMs), − hole transport materials (HTMs), − and prepared all-inorganic solar cells. , Scientists expect using various carrier materials to improve the performance and even the stability. However, very few of the reported materials have been able to achieve gratifying stability.…”

For the study, we prepared a low grain boundary three-dimensional CH 3 NH 3 PbI 3 crystal (3D-MAPbI 3 ) on TiO 2 nanoarrays by inhibition of ammonium iodide and discussed the formation mechanism of the crystal. Based on the 3D-MAPbI 3 crystal, solar cells showed modified performance with a power conversion efficiency (PCE) of up to 19.3%, which increases by 36.8% in contrast to the counterparts. We studied the internal photocurrent conversion process. The highest external quantum efficiency is up to 92%, and the electron injection efficiency is remarkably facilitated where the injection time decreases by 37.8% compared to the control group. In addition, based on 3D-MAPbI 3 , solar cells showed excellent air stability, which possesses 78.3% of the initial PCE, even though they were exposed to air for 30 days. Our results demonstrate a promising approach for the fabrication of perovskite solar cells with high efficiency and stability.
