Abstract

An inexpensive material, i.e., tetranuclear zinc(II) complex, (Zn ₄O(AID)₆) [AID = 7-azaindolate], was utilized as a cathode buffer in organic photovoltaic (OPV) devices, leading to the improvement of device performance. Compared to OPV devices based on a conventional cathode buffer of TPBi (1,3,5-tris(2-N-phenylbenzimidazolyl)benzene), although the freshly prepared devices showed similar performance, when heated to a series of high temperatures under air, the short circuit current and the open circuit voltage of the Zn₄O(AID)₆ devices dropped more slowly, indicating the superiority of using Zn₄O(AID)₆ as a cathode buffer over TPBi in OPV devices.
