Abstract

The goal of this work was to fabricate an inverse planar perovskite solar cell (PSC) that was stretchable in one dimension and completely solution-processible. Perovskites are a material that have attracted much attention in recent years due to their appealing characteristics, such as being photovoltaic and piezoelectric. PSCs have been the focus of many studies in the solar cell area, as they are solution-processible and have shown high efficiencies relative to the amount of time they have been studied. Fabricating a PSC on a stretchable substrate would be beneficial, as a bendable, stretchable PSC would likely have more applications than its rigid counterpart, such as soft robotics and smart clothing. A bendable, stretchable PSC would also potentially be able to take advantage of both the photovoltaic and piezoelectric nature of the material to increase efficiencies under stress and strain. In this work, through four iterations of design, a working PSC was unable to be produced. While the fabrication of the PSC ultimately failed, some evidence for the piezoelectric part of the design was provided, and transparent, stretchable electrodes, which are important for this technology, were successfully made.
