Perovskite solar cell based on playdough-like graphite electrodes achieves 20.29% efficiency

Researchers in China have fabricated a carbon-based perovskite solar cells that achieves almost the same efficiency as perovskite counterparts based on gold electrodes while also providing higher stability. The novel devices use a playdough-like graphite (PG) electrode that combines combines the deformable property of carbon paste and the solvent-free property of carbon film. A group of researchers led by the Wuhan University of Technology fabricated a carbon-based perovskite solar cell that uses a playdough-like graphite (PG) putty as an electrode. "The playdough-like carbon electrode is the ...
