Photovoltaic Properties

The most frequently used n-type electron transport layer (ETL) in high-efficiency perovskite solar cells (PSCs) is based on titanium oxide (TiO2) films, involving a high-temperature sintering (>450 °C) process. In this work, a dense, uniform, and pinhole-free compact titanium dioxide (TiOx) film was prepared via a facile chemical bath deposition process at a low temperature (80 °C), and was applied as a high-quality ETL for efficient planar PSCs. We tested and compared as-deposited substrates sintered at low temperatures (< 150 °C) and high temperatures (> 450 °C), as well as their corresponding photovoltaic properties. PSCs with a high-temperature treated TiO2 compact layer (CL) exhibited power conversion efficiencies (PCEs) as high as 15.50%, which was close to those of PSCs with low-temperature treated TiOx (14.51%). This indicates that low-temperature treated TiOx can be a potential ETL candidate for planar PSCs. In summary, this work reports on the fabrication of low-temperature processed PSCs, and can be of interest for the design and fabrication of future low-cost and flexible solar modules.

Perovskite solar cells have become a hot topic in the solar energy device area due to high efficiency and low cost photovoltaic technology. However, their function is limited by expensive hole transport material (HTM) and high temperature process electron transport material (ETM) layer is common device structure. Numerical simulation is a crucial technique in deeply understanding the operational mechanisms of solar cells and structure optimization for different devices. In this paper, device modelling for different perovskite solar cell has been performed for different ETM layer, namely: TiO2, ZnO, SnO2, PCBM (phenyl-C61-butyric acid methyl ester), CdZnS, C60, IGZO (indium gallium zinc oxide), WS2 and CdS and effect of band gap upon the power conversion efficiency of device as well as effect of absorber thickness have been examined. The SCAPS 1D (Solar Cell Capacitance Simulator) has been a tool used for numerical simulation of these devices.

The researchers now days are avid of solar cells despite the efficiency issues. As lead-based halide perovskite exhibit toxic nature alternatives for the anti- toxic perovskite solar cells(PSCs) are gaining much research. Bis(sulfanylidene )tungsten is a toxic free feasible emerging option with direct band gap of value 1.8 eV. Tungsten disulfide is other chemical name of Bis(sulfanylidene)tungsten. In this paper, perovskite solar cell (PSC) with Bis(sulfanylidene)tungsten (WS2 ) as electron transport layer and spiro-OMeTAD as hole transport layer is modelled and simulated using SCAPS software to analyze performance parameters. The device simulations results are compared for comprehensive defect study of WS2 as ETL. With integration of WS2 and spiro-OMeTAD in the perovskite design, the outcomes are proficient enough with 25.96% of PCE, 22.06 mA/cm2 Jsc, 1.280V Voc and 91.76% FF. Launching the batch setup for absorber layer thickness further resulted with competent PCE 27.78%. The outcomes signified that the toxic-free WS2 based PSC can be a prominent upcoming perspective in terms of environmentally pristine nature and capitulate comparative high efficiency
