One of the challenges facing wide-bandgap perovskite solar cells used as top cells in tandem structures is the large open circuit voltage (V_oc) loss compared to the Shockley-Queisser (SQ) limit, the theoretical maximum V_oc derived from the principle of detailed balance.In this study, the energy levels of the electron transport layer of inverted wide-bandgap perovskite solar cells were adjusted to obtain a V_oc close to the SQ limit.<!-- notionvc: c62de0c3-9d77-4549-9d68-5dea0d8f06cc -->
