“…HTL and ETL must carry out the following three tasks: To prevent recombination, one must (i) remove the hole or electron from the absorber layer, (ii) prevent the opposite charges from entering the layer, and (iii) collect the hole or electron from the layer and guide it towards the proper electrode [10]. TiO2 has been chosen as our ETL layer because it promotes band alignment, electron extraction from the perovskite layer, and perovskite stability [11]. Although there are several organic and inorganic polymers that can be utilised as HTL, we have chosen Spiro-OMeTAD as the most suitable option due to its easy implementation and high performance in organicinorganic electrical systems.…”

Low-power IoT sensing applications have proliferated, focusing on self-powered sensors. Accordingly, researchers have investigated serval procedures for the power management of such self-powered sensors. Obesely, minimizing the energy consumed by the sensor is critical to efficient power management. However, another challenge is still considered in harvesting energy effectively. Herein, we provide an attempt to investigate light harvesters that are capable of semi-transparent applications. Six samples were simulated under three light sources while performing a unifacial and bifacial optical injection. The optoelectronic numerical model has shown the utility of perovskite solar cells to harvest the AM1.5G solar spectrum up to 28.63%, with transparency reaching 87%. On the other hand, the bifacial condition boosted the overall cell efficiency to nearly 33% with transparency of 90%, without considering Fresnel glass reflection of 8%. The proposed bifacial cell is a primary light-harvesting source for four IoT sensing applications, including biomedical sensing, underwater harvesting, and IoT sensing in intelligent vehicles and buildings.

“…The photoactive layer has a pivotal function in light absorption, and for optimal efficiency, it necessitates a low defect density. Subpar film quality and unfavorable characteristics contribute to heightened defect states and increased recombination probability, detrimentally impacting the productivity of the device [26,43,44]. Energy defects are classified into two types: shallow and deep.…”

The increasing demand for energy and electricity and the depletion of fossil fuels are global problems. In recent years, dye-sensitized solar cell (DSSC) technologies have gained notoriety for their application in solar energy. DSSCs are considered a promising alternative renewable energy source to both inorganic and organic photovoltaic (PV) cells. Many types of dyes are being investigated to enhance the light-harvesting properties of DSSCs, but the actual realization of these absorbers in cell structure requires optimum parameters. The main aim of this study was to simulate proposed zinc phthalocyanine (ZnPC)-based structures to validate their design, assess their performance for commercial implementation, and optimize the cell parameters for optimum efficiency. To that end, Scaps-1D was employed to evaluate the performance of DSSCs to determine their optimum parameters. We found that ZnPC and isopropoxy ZnPC molecules outperform others molecules because of better optoelectronic properties. Several other parametric effects, such as photoactive layer thicknesses, doping densities, trap densities, and charge carrier mobilities, were also evaluated to observe their impact on device performance. The results show that moderate thickness, low defect density, moderate doping, and charge carrier mobility are favorable for better device performance due to low recombination losses, electrical losses, and better transport of charge carriers. The utmost power conversion efficiency values found for ZnPC- and ZnPC: PC70BM-based DSSCs after optimization were 9.50% and 9.81%. This paper also suggests a practical method for efficiently using DSSC cells by modifying factors that are significantly reliant on DSSC performance and output.
