Abstract
The recent emergence of efficient organic/inorganic lead halide perovskite compounds have the potential to transform photovoltaics technology, as they are easy to fabricate, have better stability, and possess superior power conversion efficiency. These are very promising in transforming the fields of dye-sensitized, organic, and thin film solar cells. In this research, a versatile solution-processing method called “spray+brush†(SB) has been adopted to achieve a power-conversion efficiency of 3.52% for photovoltaics by incorporating organometal halide perovskite absorbers. It has been observed that this method is more efficient and cost effective than the perovskite devices fabricated by spray (1.95%) and brush (1.17%) methods alone. The SB method of solution processing can be promising for various other organic coatings.
