Job Description

This project aims to develop novel transparent electrodes for perovskite/silicon tandem solar cells. Perovskite/silicon tandem solar cells aim to achieve the power conversion efficiencies beyond the single-junction limit of the silicon solar cells. Towards this end, developing highly transparent electrodes are critical for the maximized light-harvesting since parasitic absorption losses originating from the transparent conductive oxides cause drastic current losses.

Why we need broadband transparent electrodes on perovskite/silicon tandem solar cells?

In perovskite/silicon tandem solar cells, the perovskite top cell efficiently harvests the blue part of the solar spectrum, while transmitting the red part, which is absorbed in the silicon bottom cell. In this way, the tandems can overcome the single-junction efficiency limit of silicon solar cells. However, parasitic absorption losses originating from the transparent electrodes hinders the light-harvesting. Typically, a front transparent electrode in any solar cell has a sufficiently large (>3 eV) optical band gap to avoid absorption losses in the visible range of the spectrum. This requirement is already fulfilled by several TCOs such as ITO, IZO, and IO: H. For perovskite/silicon tandem solar cells, transparent electrodes with low absorptance in the NIR‐IR part of the spectrum are required since these devices use optical absorbers that are active in this range of the spectrum. Towards reaching >30% photoconversion efficiency, designing transparent electrodes with exceptionally large broadband transparency carriers critical importance.
