Ching W. Tang is considered by many to be the father of organic electronics. Dr. Tang describes his experiences with developing organic electronic materials at Kodak in the 1980s in an interview by Stephen Forrest and Nicole Moore in the Energy Quarterly section of MRS Bulletin.1 His early development focused on the aggregate photoconductor, which consists of a polymer, an adsorbing dye, and a hole transport material that has two interpenetrating phases. One phase is an electron conductor and the other a hole conductor. While trying to increase the performance of the solar cells to compete with CdTe, he discovered that by using the same device structure, he could get light emission. Thus, his work moved to developing OLEDs (organic light-emitting diodes). After overcoming many issues in constructing heterojunction OLEDs, a successful potential product was developed. Dr. Tang goes on to discuss the positive picture he envisions for organic OLEDs and photovoltaic devices.

I found this blog very interesting because I never before hear about this type of organic electronics. I found that in a future organic electronics can become a low-cost solar energy. Since Dr. Tang discovered the heterojunction structure, many advances have been developed. There are some researches trying to find new materials and composition to decrease the manufacturing process avoiding the high temperature processes. Another property that researchers are trying to obtain in this type of materials is the ductility because the existent materials are very brittle. So here is an interesting area to research new materials for this application.
