Plextronics, Inc. is an international technology company that specializes in printed solar, lighting and other electronics. Headquartered in Pittsburgh, PA, the company's focus is on organic solar cell and OLED (Organic Light Emitting Diode) lighting, specifically the conductive inks and process technologies that enable those and other similar applications. In printed solar cells, sunlight is collected in the photoactive layer to create charge carriers. When voltage is applied to the device, these carriers are separated into positive and negative charges and then directed to the conductive electrodes (cathode and transparent anode) to create power. The hole transport layer improves extraction of positive charges from the photoactive ink by matching of energy levels to photoactive ink. The combination of the Plexcore PV inks in a printed solar cell enables consistently improved device efficiency, which results in the ability to convert more sunlight into power.
