Publication date: 15 November 2019Source: Materials Letters, Volume 255Author(s): Amit Kumar Rana, Dong-Kyun Ban, Malkeshkumar Patel, Ju-Hyung Yun, Joondong KimAbstractThe present study shows the energy harvesting ability from a transparent Cu2O/ZnO/AZO heterojunctions device. Particularly, the electron selective AZO/ZnO and hole selective Cu2O enables the formation of photovoltaic behaviour with a VOC of 0.52 V. It is demonstrated that even with high transparency of the photoactive oxide layers of ∼80%, the device shows the maximum conversion efficiency of ∼0.70% depending on the incoming photon intensity. In addition, wavelength-selective performance of the device demonstrates a maximum responsivity of 2.13 A/W towards 400 nm. This transparent device architecture study will serve the foundation to be useful to design advanced see-through devices beyond the energy generation entities to be applied in power generating windows and skyscrapers.
