Photo-electrical Properties of Transparent Conductive Materials in Hybrid Perovskite Solar Cells

Abstract

Since their emergence about ten years ago, perovskite solar cells show great promise. Indeed, they have achieved performances comparable to those of silicon cells and have good flexibility properties. However, their transparent conductive electrodes - transparent conductive oxides -, are not only composed of scarce elements but are also quite fragile. In the present work, silver nanowire networks will be suggested as a more viable alternative. For this purpose, the production process of perovskite solar cells will be analyzed step by step, allowing the identification of the stresses experienced by the cells. Similarly, silver nanowire networks will be produced and characterized in order to determine what stresses they can withstand. It will be found that in the case of replacement, two main factors can cause problems: the high production temperatures of the cells and the low adhesion of the nanowire networks. Various solutions will be proposed for successful replacement.
