carbon nanosheet

How to manufacture transparent and conductive carbon nanosheet using PIM-1 polymer solution: (a) Quart substrate is being coated with PIM-1 polymer solution with ladder structure and conducts heating in high temperature to manufacture carbon nanosheet. Without any additional process OSC (organic solar cell) can be made directly on the sheet to manufacture solar cells. (b), (c), (d) show thickness, surface resistivity and transparency of the carbon nanosheet, respectively in relation to the concentration of PIM-1. Also, the new method easily controls the unwanted effects from the electronic and optical characteristics of carbon nanosheet, which is produced when the polymer solution is concentrated. As the high molecule solution concentration gets higher as shown in (Axis X, (b),(c)), the thicker it gets as shown in Figure (b) but, it becomes less resistant as shown in Figure (c), and the current flow better.
