Turbulence effects on bremsstrahlung emission due to the electron-ion interaction were investigated in the turbulent solar plasma. The effective interaction potential, taking into account the correction factor to the nonlinear dielectric function due to plasma turbulence, and the impact-parameter method were employed in order to obtain the bremsstrahlung radiation cross section in a turbulent plasma as a function of the impact parameter, diffusion coefficient, radiation photon energy, projectile energy, and plasma parameters. It has been shown that the turbulence effects considerably enhance the bremsstrahlung radiation cross section. In addition, it was found that the turbulence effects of the solar atmosphere on the bremsstrahlung cross section increase with increasing radiation photon energy, but decrease with increasing thermal energy. It can be expected that the Landau damping effect on the bremsstrahlung spectrum from the solar corona is less important than that from the solar chromospheres due to temperature jumps. However, the effect of the plasma turbulence on the bremsstrahlung spectrum from the solar chromosphere would be smaller than that from the solar corona.
