Abstract

Organic-inorganic metal halide perovskite solar cells (PSCs) have received considerable global attention due to their low-cost technology, ease of processing, and excellent photovoltaic performance. One of the distinctive properties of perovskite is to become semitransparent by various means such as compositional engineering, varying concentrations of precursor, spin speed, and/or thickness. This has led to a research focus on high-performance semi-transparent perovskite solar cells (ST -PSCs) with a potential market scope of applications in building integrated architectures, tandem solar cells, automobiles, flexible and wearable electronics, agrivoltaics, and solar trees. However, obtaining high visible transparency along with high power conversion efficiency (PCE) is particularly challenging. We have fabricated semi- transparent perovskite solar cells with acetamidinium- substituted methylammonium lead iodide perovskite layer with average visible transmittance (A VT) over 25% by tuning the concentration of perovskite precursors. The ST -PSC devices exhibited a PCE of 7.4% to 15.1 % for different concentrations. These results find a variety of applications for ST -PSCs in tandem configuration with various low-bandgap materials such as Si, CIGS, organic, and all-perovskite tandem architectures.
