Mechanism of Electronegativity Heterojunction of Nanometer Amorphous-Boron on Crystalline Silicon: An Overview

Amorphous silicon on p-type crystalline silicon heterojunction

2014 A junction was grown by d.c. sputtering of n-type silicon on a p-type crystalline substrate. Ohmic contacts were deposited by evaporation of aluminum. The junction obeyed Schottky model both under forward and reverse bias conditions, but with higher idealization factor « n » due to its high internal resistance. The 1/C2-V relation showed the presence of localized and interface states. The ...

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. ...

Analysis of lateral transport through the inversion layer in amorphous silicon/crystalline silicon heterojunction solar cells

In amorphous/crystalline silicon heterojunction solar cells, an inversion layer is present at the front interface. By combining numerical simulations and experiments, we examine the contribution of the inversion layer to lateral transport and assess whether this layer can be exploited to replace the front transparent conductive oxide (TCO) in devices. For this, heterojunction solar cells of dif...

On the amorphous silicon on crystalline silicon heterojunctions

2014 Accurate analysis and reinterpretation of recent results of a-Si heterojunctions have removed inconsistency of spectral and electrical measurements. Results of Schottky barriers and Mott-Schottky dispersion are discussed. Revue Phys.
