A growing number of indoor microelectronic devices with low consumption (average power of mW) require a power source to which Photovoltaic modules can contribute. However, Photovoltaic devices are rated by their power output under Standard Test Conditions (STC), and the 1 sun (AM1.5, 1000W/m) intensity used for these tests is several orders of magnitude above what is found indoors. A study was ...
In photovoltaic devices, the photo-generated charge carriers are typically assumed to be in thermal equilibrium with the lattice. In conventional materials, this assumption is experimentally justified as carrier thermalization completes before any significant carrier transport has occurred. Here, we demonstrate by unifying time-resolved optical and electrical experiments and Monte Carlo simulat...
Iron pyrite (FeS(2)) is a naturally abundant and nontoxic photovoltaic material that can potentially make devices as efficient as silicon-based ones; however existing iron pyrite photovoltaic devices contain thermodynamically unstable FeS(2) film surfaces that lead to low open circuit voltages. We report the rational synthesis of phase pure, highly crystalline cubic FeS(2) nanocrystals (NCs) us...
