Abstract

Perovskite solar cell (PSC) is a type of solar cell in which the active material is formed using an organicinorganic halide. PSCs have shown rapid development over the past 10 years with an increase of efficiency up to 22.11%. However, organic compounds used in the development of PSC have often failed to show strong resistance towards moisture and oxygen, thus resulting in rapid cell degradation. In order to compensate for its weak characteristics when exposed to moisture and oxygen during the fabrication process as well as operation time where ambient air is present, trap passivation is a method that can be employed to prevent charge trap state caused by the non-uniformity at the active cell interlayer surface. In this paper, we applied 3 levels of tetraethyl orthosilicate (TEOS) concentration into perovskite active layer in order to find which level of concentration brings out the best Voc, Isc and Fill Factor of the perovskite solar cell. In this research, we obtained the best result with 0.3%mol of applied TEOS additive into the perovskite active layer with Voc, Isc, and FF value of 0.76 V, 3.96 mA, and 0.4563 respectively.
