Quantum Efficiency Modeling of Amorphous/Crystalline Silicon Heterojunction Photovoltaic Devices

چکیده
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. We considered low-quality (low bulk lifetime), cheaper substrates. Thin, low bulk lifetime substrates in combination with a low-T bulk passivation scheme and low rear surface recombination can lead to a cost effective device fabrication process with competitive conversion efficiency.

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 ...

Thin films of Si nanocrystals (Si NCs) embedded in a silicon carbide (SiC) matrix (Si-NC:SiC) were prepared by alternating deposition of Si-rich silicon carbide (Si1 xCx) and near-stoichiometric SiC mutilayers (Si1 xCx/SiC) using magnetron cosputtering followed by a post-deposition anneal. Transmission electron microscopy and Raman spectroscopy revealed that the Si NCs were clearly established,...
