Abstract This work mainly focuses on synthesizing and evaluating the efficiency of methylammonium lead halide‐based perovskite (MAPbX 3 ; X=Cl, Br, I) solar cells. We used colloidal Hot‐injection method (HIM) to synthesize MAPbX (X=Cl, perovskites using specific precursors organic solvents under ambient conditions. studied structural, morphological optical properties XRD, FESEM, TEM, UV‐Vis, PL TRPL (time‐resolved photoluminescence) characterization techniques. The particle size morphology these vary with respect halide variation. MAPbI possesses a low band gap carrier lifetime but delivers highest PCE among other samples, making it promising candidate for cell technology. To further enrich investigations, conversion has been evaluated through extensive device simulations. Here, constants, energy were simulating three different cells, namely I, Cl or Br , MAPbBr MAPbCl absorber layer‐based devices showed ~13.7 %, 6.9 % 5.0 efficiency. correlation between experimental SCAPS simulation data HIM‐synthesized MAPBX ‐based reported first time.
