Perovskite solar cells (PSCs) made with metal halide are affordable and can give better efficiency values than older versions but their low is still a concern. Two were fabricated one had Multi wall Carbon nanotube (MWCNT) in its design. The effect of the Multi-wall on performance power conversion studied. MWCNT m-TiO2 materials characterised using UV-vis spectroscopy optical energy band gap obtained. TiO2 showed prominent peak at 319 nm absorbance 0.5 bandgap 2.59 eV falls visible region showing it clean source implications for conversion. has 2.19 multiple peaks.
