Crystallite size and grain size
WebMay 18, 2015 · The average crystallite size ( D) of each sample is estimated from the well-known Scherrer’s equation, which is given below: D = k λ β hkl cos θ hkl (3) Where k is the shape factor, λ is the wavelength of X-Ray, θhkl is the Bragg angle and βhkl is the corrected full width at half maximum ( FWHM ). WebThe crystallinity properties of perovskite influence their optoelectrical performance in solar cell applications. We optimized the grain shape and crystallinity of perovskite film by annealing treatment from 130 to 170 °C under high humidity (relative humidity of 70%). We found that the grain size, grain interface, and grain morphology of the perovskite …
