Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers (nm) to a few microns (μm) thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick. Thi…
Here, we report on a high efficiency thin film (<200 nm) perovskite solar cell. An ∼170 nm-thick ethylammonium lead iodide (EAPbI 3) film is stamped with a methylammonium (MA)-reservoir MAPbI 3 film. A facilitated cation transport during stamping results in a phase conversion from orthorhombic EAPbI 3 to cubic MAPbI 3, along with an enlarged grain size. 1 H NMR study …
