“…On the other hand, lower PCE compared to the other reported simulation of bulk-hybrid solar cells is maybe due to the incorporation of a higher density of traps [ 38 ]. It is experimentally evident that polymers are full of traps, and these traps may be presented due to many factors such as humidity, structural defects, distortion, impurity, and/or any other known or unknown reasons.…”

Polymer semiconductors may have the potential to fully replace silicon in next-generation solar cells because of their advantages such as cheap cost, lightweight, flexibility, and the ability to be processed for very large area applications. Despite these advantages, polymer solar cells are still facing a certain lack of power-conversion efficiency (PCE), which is essentially required for commercialization. Recently, bulk heterojunction of PTB7:PC70BM as an active layer showed remarkable performance for polymer solar cells in terms of PCE. Thus, in this paper, we developed and optimized a novel design using PEDOT:PSS and PFN-Br as electron and hole transport layers (ETL and HTL) for ITO/PEDOT:PSS/PT7B:PC70BM/PFN-Br/Ag as a polymer solar cell, with the help of simulation. The optimized solar cell has a short-circuit current (Isc) of 16.434 mA.cm−2, an open-circuit voltage (Voc) of 0.731 volts, and a fill-factor of 68.055%, resulting in a maximum PCE of slightly above 8%. The findings of this work may contribute to the advancement of efficient bulk-heterojunction-based polymer solar cells.

Effective conversion of solar photons into electrical power through the development of smart and eco‐friendly materials is one of the most extensively researched methods for generating renewable energy. In this work, an inorganic lead‐free double perovskite Cs2SnI6 material is employed as an active layer for solar cell applications, together with GO (graphene oxide) as electron transport layer (ETL) and Cu2O as hole transport layer (HTL). In order to find the most efficient photovoltaic device, a detailed theoretical study using the SCAPS‐1D simulation program is conducted. The device performance is monitored and analyzed by considering various HTLs, doping density in active layer, light intensity, ETL thickness, operating temperature, parasitic resistances, and the role of defects on device performance. The optimized device displays a power conversion efficiency of 23.64% with excellent photovoltaic characteristics. This theoretical study reveals that Cs2SnI6 can be a promising choice for solar cell applications as a lead‐free double perovskite material.

Summary The state‐of‐art charge transport materials, TiO2 and Spiro‐OMeTAD suffer from various drawbacks such as instability, lengthy fabrication procedure and low charge mobilities. In this paper, we have studied copper phthalocyanine (CuPc) and halogen‐substituted copper phthalocyanine (X16CuPc; X = F, Cl, Br, I) through density functional theory (DFT) and determined their ground state properties, excited state properties and solubility in DMSO (widely used solvent in the fabrication of perovskite solar cell [PSC]). We have shown that fluorinated copper phthalocyanine(F16CuPc) acts as an electron transport layer (ETL) and CuPc acts as a hole transport layer (HTL) in MAPbI3‐based PSC. The moisture stability of CuPc and F16CuPc has been established and it has been shown that CuPc and F16CuPc will protect the perovskite layer from degradation due to the presence of moisture in the surroundings. Using the properties obtained via DFT, PSC has been simulated using SCAPS, and it is established that CuPc as hole transport material and F16CuPc as electron transport material gives better efficiency compared with the state of art charge transport materials (TiO2 and Spiro‐OMeTAD). The device has been optimized with respect to (w.r.t.) thickness, doping concentration, defect density and interface defect density. We have studied the effect of series resistance, shunt resistance and temperature on the performance of PSC and this configuration has shown good thermal stability. Carbon has been proposed as an alternative to gold as the back contact thereby making our device more economical. The optimized device showed quantum efficiency of (81.59% to 98.69%) in the visible region. A fill factor of 79.01%, power conversion efficiency of 22.30% has been obtained.
