Carrier transport layer free perovskite solar cell for enhancing the efficiency: A simulation study

Comparative Study of Distinct Halide Composites for Highly Efficient Cesium-Based Perovskite Solar Cells

“…In the past ten years, numerous investigators have conducted studies on perovskite solar cells (PSCs) and observed a substantial improvement in their PCE. − The exceptional characteristics of these materials, such as a significantly high absorption coefficient, an adjustable band gap, an extended carrier diffusion length, enhanced carrier mobility, a reduced trap state density, a lower excitons binding energy, and a cost-effective processing method, have facilitated their achievement of this remarkable accomplishment. − The typical perovskite composition is presented by the chemical formulation ABX 3 , wherein A represents an inorganic or organic cation (MA, FA/Cs) and B represents a heavy metal (Sn, Pb, Ge), followed by an X signifying a halide anion (Cl, Br, and I). − The hybrid organic–inorganic perovskites have blazed a trail toward a more efficient light-harvesting material. PSC efficiency has now increased from 3% to 25.6%. − The versatile frequency of the PSCs enables them to efficiently capture the light of varying frequencies in different layers, thereby enhancing PCE. − …”

Comparative study of distinct halide composites for highly efficient perovskite solar cells using a SCAPS-1D simulator

“…16–20 Because of the tunable frequency, the PCSs can absorb different light frequencies effectively in different layers, improving PCE. 21–26…”

“…[16][17][18][19][20] Because of the tunable frequency, the PCSs can absorb different light frequencies effectively in different layers, improving PCE. [21][22][23][24][25][26] Many previous studies have been conducted on perovskite materials consist of Pb, which are the most efficient and reliable. 27 These PSCs have their own set of advantages and disadvantages, such as high efficiency and stability but poor performance, high stability but not eco-friendly, and so on.…”

Perovskite Solar Modules: Design Optimization

“…Kaity et al used a simulation software (SCAPS-1D) to investigate the device performance with different parameter variations [absorber thickness, doping concentration, defect density, absorber/electron transport layer (ETL) interface defect density, ETL, and hole transport layer (HTL) doping concentrations] for a lead-free perovskite device . Bhattarai et al also used a simulation tool (SETFOS Fluxim 4.6) to study the best suitable design for a perovskite cell without carrier transport layers since these provide a great source for stability loss . In this work, a simulation software device (LAOSS) was used to study the best design and dimension of a large-area PSC, considering both electrical output and adaptability to building integration.…”
