Clip the edges (the two without the 4mm strip s) with binder clips to hold the cell together. The significant photocurrent Use a graphite pencil to cover the conductive side with a thin layer of graphite (conductive carbon) and remove the tape. This carbon acts as a catalyst for converting triiodide to iodide. Even for a simple heterojunction device, considerable improvement in the short-circuit current was obtained as compared to other TiO 2 /MEH-PPV devices reported in the literature. The Grätzel cell is has been the focus of years of research but has failed to become a commercial success. Make sure the binder clips are just on the edge of the cell not covering the coated area.

The mesoporous TiO2 nanoparticle-based scaffold structure is the best electron transport layer (ETL) for perovskite solar cells (PSCs) and is still used in most PSCs with optimal photovoltaic characteristics. Solar cell sensitized by only CdS exhibits a short-circuit photocurrent density (J SC) of 5.7 mA/cm 2 and an open-circuit voltage (V OC) of 0.39 V. On the other hand, solar cell sensitized by only PdS present a poor photovoltaic performance with very low J SC and V OC. Use a multimeter and attach the alligator clips to your cell: one clip on each side. Set the meter to measure Ohms and put both leads on one side of the slide, if the resistance measured is near zero, that is the conductive side.
