Although perovskite solar cells with power conversion efficiencies (PCEs) more than 22% have been realized with expensive organic charge-transporting materials, their stability and high cost remain to be addressed. In this work, the perovskite configuration of MAPbX (MA = CH3NH3, X = I3, Br3, or I2Br) integrated with stable and low-cost Cu:NiOx hole-transporting material, ZnO electron-transporting material, and Al counter electrode was modeled as a planar PSC and studied theoretically. A solar cell simulation program (wxAMPS), which served as an update of the popular solar cell simulation tool (AMPS: Analysis of Microelectronic and Photonic Structures), was used. The study yielded a detailed understanding of the role of each component in the solar cell and its effect on the photovoltaic parameters as a whole. The bandgap of active materials and operating temperature of the modeled solar cell were shown to influence the solar cell performance in a significant way. Further, the simulation results reveal a strong dependence of photovoltaic parameters on the thickness and defect density of the light-absorbing layers. Under moderate simulation conditions, the MAPbBr3 and MAPbI2Br cells recorded the highest PCEs of 20.58 and 19.08%, respectively, while MAPbI3 cell gave a value of 16.14%.

“…The thickness increases when high RF power values also increase during the AZO thin films process. The thickness values of AZO thin films were around 250 nm that is the thickness that is usually used in solar cells multilayers; improving the device efficiency without increasing its resistivity, in the opposite case, if a layer had more thickness the incident light couldn't reach the absorber layers [17,18]. The surface roughness values of AZO thin films were around 55 nm and no clear correlation was observed between the surface roughness and the power used in the processing of AZO films.…”

A study of transparent thin films of Zinc Oxide doped with Aluminum (AZO) processed by sputtering with potentials application as substrate for single wall carbon nanotubes processing by spray-coating is discussed in this work. AZO Thin films have been deposited by radiofrequency magnetron sputtering technique at room temperature in high vacuum ambient and using an Argon atmosphere. The AZO thin films and the processed bilayers of Zinc Oxide: Aluminum/Single wall carbon nanotubes were characterized by scanning electron microscopy, Raman spectroscopy, X-ray diffraction, ultraviolet-visible spectrophotometry, stylus profilometry and four-terminal method for the electrical resistivity measurement. The feasibility of the Zinc Oxide doped with Aluminum thin films for its use as single wall Carbon Nanotubes substrate processed by a low-cost technique, with potential application in the configuration of photovoltaics devices is presented, analyzed and discussed as function of its electrical, morphological and optical properties through Haacke figure of merit quantification. A two-order reduction in resistivity values, average acceptable transmittance values (∽80%), and crystallinity expected for polycrystalline films were obtained for AZO/Single wall carbon nanotubes bilayers; although the homogeneity of the single wall carbon nanotubes distribution on AZO thin films processed by RF-Sputtering should be improved, the possible application as transparent electrode in a usual configuration of solar cells of AZO/Single wall carbon nanotubes can be performed.

A depth behavioral understanding for each layer in perovskite solar cells (PSCs) and their interfacial interactions as a whole has been emerged for further enhancement in power conversion efficiency (PCE). Herein, NiO@Carbon was not only simulated as a hole transport layer but also as a counter electrode at the same time in the planar heterojunction based PSCs with the program wxAMPS (analysis of microelectronic and photonic structures)-1D. Simulation results revealed a high dependence of PCE on the effect of band offset between hole transport material (HTM) and perovskite layers. Meanwhile, the valence band offset (∆E v ) of NiO-HTM was optimized to be −0.1 to −0.3 eV lower than that of the perovskite layer. Additionally, a barrier cliff was identified to significantly influence the hole extraction at the HTM/absorber interface. Conversely, the ∆E v between the active material and NiO@Carbon-HTM was derived to be −0.15 to 0.15 eV with an enhanced efficiency from 15% to 16%.
