PEROVSKITE SOLAR CELLS ON PAPER AND THE ROLE OF SUBSTRATES AND ELECTRODES ON PERFORMANCE

on paper perovskite solar cells

The first perovskite solar cell (PSC) fabricated directly on a paper substrate with a maximum power conversion efficiency of 2.7% is here reported. The paper PSCs (PPSC) were developed with a low-temperature Paper/Au/SnO2/meso-TiO2/CH3NH3PbI3/Spiro-OMeTAD/MoOx/Au/MoOx architecture utilizing a Au/SnO2 and MoOx/Au/MoOx stack as electron- and hole- extracting electrodes respectively. The transparent MoOx/Au/MoOx electrode had a favourable combination of transmittance (62.5%) and sheet resistance (9 Ω/â–¡). By comparing performance of cells on paper with those fabricated on glass and plastic films with different electrodes, we identify avenues that can help guide future research for improved performance. All the deposition processes used are scalable and compatible with large area printing or evaporation technologies. Paper represents a lightweight, flexible, inexpensive, ubiquitous, and environmentally friendly material, paving the way for integrating perovskite technology with other electronic components as well as for the development of stand-alone PV devices on recyclable and low-cost paper substrates.
