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

Research in solar cells is needed to maximize Indonesia’s vast solar potential that can reach up to 207.898 MW with an average radiation of 4.8 kWh/m2/day. Organometallic perovskite solar cells (PSCs) have gained immense attention due to their rapid increase in efficiency and compatibility with low-cost fabrication methods. Understanding the role of hole transport layer is very important to obtain highly efficient PSCs. In this work, we studied the effect of Hole Transport Layer (HTL) to the performance of perovskite solar cell. The devices with HTL exhibit substantial increase in power conversion efficiency, open circuit voltage and short circuit current compared to the device without HTL. The best performing device is PSC with CuSCN as HTL layer, namely Voc of 0.24, Isc of 1.79 mA, 0.27 FF and efficiency of 0.09%.

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.

AbstractOver the past number of years, the power conversion efficiency of perovskite solar cells has remained at 25.5%, reflecting a respectable result for the general incorporation of organometallic trihalide perovskite solar cells. However, perovskite solar cells still suffer from long-term stability issues. Perovskite decomposes upon exposure to moisture, thermal, and UV-A light. Studies related to this context have remained ongoing. Recently, research was mainly conducted on the stability of perovskite against non-radiative recombination. This study improved a critical instability in perovskite solar cells arising from non-radiative recombination and UV-A light using a passivation layer. The passivation layer comprised a polyaniline (PANI) polymer as an interfacial modifier inserted between the active layer and the electron transport layer. Accordingly, the UV-A light did not reach the active layer and confined the Pb2+ ions at PANI passivation layer. This study optimized the perovskite solar cells by controlling the concentration, thickness and drying conditions of the PANI passivation layer. As a result, the efficiency of the perovskite solar cell was achieved 15.1% and showed over 84% maintain in efficiency in the ambient air for one month using the 65 nm PANI passivation layer.
