few years. This has spawned a lot of interest in investigating the commercial scalability of the
perovskites by reducing the cost. Carbon can act as a cheaper alternative to gold and
aluminium to act as counter electrode. In the present study, we have tuned the perovskite
layer by the addition of FA (Formamidinium) and Cs (Cesium) through compositional
engineering. The optimized configuration of perovskite was then utilized in carbon …
