Organic photodetectors device structure

Many variations of the basic OLED device structure have been investigated. The basic OLED structure can also be used for organic photodetectors and photovoltaic cells. 

Conjugated polymers, in the undoped state, exhibit the electronic and optical properties of semiconductors in combination with the mechanical properties of general polymers, making them potentially useful for a wide array of applications particularly in organic optoelectronic devices such as polymer LEDs, photodetectors, photovoltaic cells, etc. Development in the performance of such devices has advanced rapidly, and prototype devices now meet realistic specifications for practical applications. In spite of such successful achievements in the scope of device application, however, there is still controversy over the nature of the electronic structure and the appropriate description of the underlying physics of elementary excitations. Since these issues are both scientifically interesting and critically important to the assessment of the future potential of devices based on conjugated polymers, more detailed...
