Numerical Simultion of FTO/ZnO/CH₃NH₃SnBr₃/Spiro-OMeTAD/Au Lead free Perovskite Solar Cell

We present a succinct numerical simulation report on improved functioning lead-free CH<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>NH<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>SnBr<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> perovskite solar cells (PSCs) using SCAPS-1D. Our investigations involve the depth analysis with different hole transport material layers (HTL) and electron transport material layers (ETL) to augment efficiency. Apart from this, we also studied the effect of thickness of active perovskite layer (~0.1–1.2 µm) and temperature analysis (300 to 450 K).
