Hybrid-Photovoltaics - TP4


Abstract


The energy level alignment between organic and inorganic materials was
investigated and tailored. This has important implications for adjusting the
energy levels at organic/inorganic heterojunctions and their excitons
dissociation capability, and thus, must be taken into account when designing
interfaces in photovoltaic cells.
