Photoconductivity of Quantum Dot Films Towards Third-Generation Solar Cells

Colloidal semiconductor nanoparticles, also called quantum dots, have unique opto-electronic properties that make them promising candidates for many applications such as solar cells, light–emitting diodes, lasers, or biological imaging. One of the most interesting features is that the bandgap energy can be tuned by changing the particle size....

Photo-physical processes in materials for photovoltaic applications based on conjugated polymers

Because of an increasing need for energy, exhaustion of conventional energy sources and pollution of the environment, the development of renewable energy supplies becomes increasingly important. Solar cells can play an important role to meet these demands, since they can directly convert solar light into electricity. Conventional solar cells...
