Simulation and optimization of CH3NH3SnI3 based inverted perovskite solar cell with NiO as Hole transport material

Numerical Simulation and Performance Evaluation of Highly Efficient Sb2Se3 Solar Cell with Tin Sulfide as Hole Transport Layer

“…The minimal current due to the insufficient photoinduced charge carriers with thicker ETL may be responsible for the stable solar cell output characteristics. [ 75 ] Therefore, a thin CdS ETL of 0.05 μm is optimized to get better photovoltaic performances in the following calculations. At the optimum ETL thickness of 0.05 μm, an efficiency of 29.89% with a V oc of 0.705 V, a J sc of 51.40 mA cm −2 , and an FF of 82.50% is estimated.…”

Synergistic Engineering of the Conductivity and Surface Properties of PEDOT:PSS-Based HTLs for Inverted Tin Perovskite Solar Cells to Achieve Efficiency over 10%

“…The rapid improvement in device efficiency and stability makes TPSC a very attractive technology for the photovoltaic community. Several review articles can be found, which focus on introducing the potential of Sn-based perovskite materials to be applied in the photovoltaic devices. − More encouragingly, simulation models suggested that a maximum PCE of more than 20% can be achieved for TPSCs . However, until now, the efficiency and stability of TPSCs are still much worse than lead-based cells because of TPsk have suffered from a few intrinsic problems (or fundamental obstacles), such as fast crystallization, low defect tolerance, and facile oxidation of Sn 2+ to Sn 4+ as well as the optimal charge transporting layers (CTLs) having energy levels well-matched with TPsk was not found yet.…”

A great effort 26−28 had been made to suppress the oxidation of Sn 2+ or reduce the amount of Sn 4+ in the precursor solution using a reducing agent as an additive.…”

Design and Modelling of Eco-Friendly CH3NH3SnI3-Based Perovskite Solar Cells with Suitable Transport Layers

“…The main goal of this simulation is to compare the effect of defects density of different ETL materials for SnX 3 -based perovskite solar cells. PCMB, TiO 2 , and WO 3 have been described as ETLs for SnX 3 -based perovskite solar cells in the literature [38][39][40][41][42][43][44]. Besides this, there are a limited number of reports on CuO as HTL [45,46].…”
