| description |
We demonstrate the effect of sheet conductivity and infiltration using the example of two graphite types, showing that, in general, the graphite type is very important. Amorphous and pyrolytic graphite were applied to carbon electrodes in fully printable carbon-based multiporous-layered-electrode perovskite solar cells (MPLE-PSCs): <glass/F-doped SnO<sub>2</sub>/compact-TiO<sub>2</sub>/porous-TiO<sub>2</sub>+perovskite/porous-ZrO<sub>2</sub>+perovskite/porous-carbon+perovskite>. The power conversion efficiency (<i>PCE</i>) using amorphous graphite-based carbon (AGC) electrode was only 5.97% due to the low short-circuit photocurrent density (<i>J</i><sub>sc</sub>) value, which was due to the low incident photon-to-current efficiency (IPCE) in the short wavelength region caused by the poor perovskite filling into the porous TiO<sub>2</sub>-ZrO<sub>2</sub> layers. Conversely, using pyrolytic graphite-based carbon (PGC) electrode, <i>J</i><sub>sc</sub>, open-circuit photovoltage (<i>V</i><sub>oc</sub>), fill factors (<i>FF</i>), and <i>PCE</i> values of 21.09 mA cm<sup>−2</sup>, 0.952 V, 0.670, and 13.45%, respectively, were achieved in the champion device. PGC had poorer wettability and a small specific surface area as compared with AGC, but it had better permeability of the perovskite precursor solution into the porous TiO<sub>2</sub>/ZrO<sub>2</sub> layers, and therefore a denser filling and crystallization of the perovskite within the porous TiO<sub>2</sub>/ZrO<sub>2</sub> layers than AGC. It is confirmed that the permeability of the precursor solution depends on the morphology and structure of the graphite employed in the carbon electrode. |
