In this thesis, generating of Primordial Black Holes (PBHs) and their induced gravitational waves have been investigated. An inflationary model with non- minimal coupling between gravity and field derivatives, for quartic potential with reheating consideration and exponential potential have been considered. With appropriate choosing of coupling parameter and tuning the parameters of model in this setup, the inflaton is slowed down by gravitationally enhanced friction, and the mutation of field enters an Ultra Slow Roll phase. In this phase the amplitude of curvature perturbations power spectrum experiences enough enhancement to produce PBHs with different masses. So as to attain a criterion for generation of PBHs in radiation dominated era, the reheating considerations for the model with quartic potential are taken into account. In this framework, generation of five cases of PBHs for quartic potential and four cases for exponential potential in permitted observational domains are foretold. Three cases of them with masses around (10−12)M⊙, (10−13) , and (10−15)M⊙ are suitable candidates for the entire Dark Matter content of the cosmos (M⊙ denotes the solar mass) . Two other cases of these PBHs with masses of order (10)M⊙ and (10−6)M⊙ are proper to expound LIGO-Virgo events and microlensing events in OGLE data. Thereafter, the spectra of current density parameter of propagated Gravitational Waves from foretold PBHs by the model, ΩGW0, are computed, and consistency with sensitivity curves of multifarious gravitational waves detectors have been inquired. Our numerical results exhibit that the spectra of ΩGW0 behave as a power-law function with respect to frequency, Ω_GW0 (f)~(f/f_c )^n, in the vicinity of climaxes. Also, in the infrared regimef≪f_c, the power index satisfies the relation n=3-2/ln⁡(f_c/f).
