We investigate the formation of molecular hydrogen (H_2_) in a primordial H + He gas cloud irradiated by a power-law UV flux. We find that at high densities (~>1 cm^-3^) and low temperatures (<~10^4^ K), the background radiation enhances the formation of H_2_ and results in molecular cooling dominating over photoionization heating. This process could accelerate the collapse and fragmentation of dense objects at high redshifts.
