Research Impact & Significance – Solar Cells harvest the energy of light by promoting electrons to a higher energy excited state of a dye molecule. Ideally, these high energy electrons can be efficiently collected by semi-conducting films to produce electricity (dark cells on the left and the right). Conversely it can also relax back down to the original ground state by emitting light to release that energy (bright cells on top and bottom).
To eventually increase the collection yield of electrons by the semiconductor, these excited states must be studied on their own to distinguish contribution of each process. This is why we prepared the cells shown here, to run photo-physical experiments analyzing the excited state characteristics.
