Quantum modeling of two-level photovoltaic systems

Quantum modeling of two-level photovoltaic systems

We present a quantum formalism that provides a quantitative picture of the fundamental processes of charge separation that follow an absorption event. We apply the formalism to two-level photovoltaic cells and our purpose is to pedagogically explain the main aspects of the model. The formalism is developed in the energy domain and provides detailed knowledge about existence or absence of locali...

Sliding Mode Control of Two-Level Quantum Systems

In [Dong and Petersen, Sliding Mode Control of Two-Level Quantum Systems, arXiv:1009.0558, quant-ph, 2010], a sliding mode control approach has been proposed for twolevel quantum systems to deal with bounded uncertainties in the system Hamiltonian. This paper further extends these results in two directions. One extension is to consider the effect of uncertainties during the process of driving t...

Quantum Efficiency Modeling of Amorphous/Crystalline Silicon Heterojunction Photovoltaic Devices

Amorphous/crystalline silicon (a-Si/c-Si) heterojunctions are of particular importance in photovoltaic (PV) energy conversion in a cost-effective way. This is principally due to the low temperature (low-T) nature of the process. In this work, we have analyzed a (n)a-Si/(i)a-Si/(p)cSi heterojunction solar cell structure using theoretical models for internal quantum yield (IQY) and I-V behavior. ...
