We consider the Schrödinger operator \({\mathcal {L}}=-\Delta +V\) on \({\mathbb {R}}^n,\) where \( n\ge 3\) and the nonnegative potential V belongs to reverse Hölder class \(RH_{s}\) for \(s>\frac{n}{2}.\) Let \(H^p_{\mathcal {L}}({\mathbb {R}}^n)\) denote the Hardy space related to \({\mathcal {L}}\) and \(BMO_{{\mathcal {L}}}({\mathbb {R}}^n)\) denote the dual space of \(H^1_{{\mathcal {L}}}({\mathbb {R}}^n).\) In this paper, we consider the operator \(T_{\alpha ,\beta }=V^\alpha {\mathcal {L}}^{-\beta }\) and its adjoint operator \(T^*_{\alpha ,\beta },\) where \(0<\alpha \le \beta < n/2.\) We show that \(T_{\alpha ,\beta }\) is bounded from \(H^{p_1}_{{\mathcal {L}}}({\mathbb {R}}^n)\) into \(L^{p_2}({\mathbb {R}}^n)\) for \(\frac{n}{n+\delta '}<p_1\le 1\) and \(\frac{1}{p_2}=\frac{1}{p_1}-\frac{2(\beta -\alpha )}{n},\) where \(\delta '=\min \{1, 2-n/q_0\},\) and \(q_0\) is the reverse Hölder index of V. Moreover, we prove that \(T^*_{\alpha ,\beta }\) is also bounded from \(L^{p_1}({\mathbb {R}}^n)\) into \(BMO_{{\mathcal {L}}}({\mathbb {R}}^n)\) for \(p_1=\frac{n}{2(\beta -\alpha )}.\)
