UNDERSTANDING TRANSPORT AND RECOMBINATION IN ORGANIC SEMICONDUCTORS – CAN WE RECOVER 0.2eV OF OPEN CIRCUIT VOLTAGE?

Organic semiconductors exhibit multi-scale phenomena which impact device performance in different ways. In this talk I will discuss some fundamental issues related to charge and heat transport in such films and then make some approximations to end up with a simple system one can benefit from its analysis. This will be followed by discussion of organic solar cells, their mode of operation, and we’ll see that the stampede towards perovskites is not always justified.
