Modeling on Directional solidification of Silicon for Solar Cell Applications

The Directional Solidification is a very important technique for growing high quality multi-crystalline silicon at large scale for PV solar cells. The physics governing the growth of multi-crystalline silicon in the Directional Solidification System involves complex non-linear transport phenomena including but not limited to heat transfer, solidification, thermal stress development, and the for...

Study of Dislocations in the Minicrystallized Regions in Multicrystalline Silicon Grown by the Directional Solidification Method

Directionally solidified multicrystalline silicon (mc-Si)-based solar cells have dominated the global photovoltaic market in recent years. The photovoltaic performance of mc-Si solar cells is strongly influenced by their crystalline defects. The occurrence of minicrystallization results in much smaller grain size and, therefore, a larger number of grain boundaries in mc-Si ingots. Dislocations ...

Cellular instabilities in directional solidification

2014 We have studied the morphology of the solid-liquid interface during the directional solidification of thin (5-150 03BCm) samples of a dilute binary mixture (CBr4/~ 0.1 % Br2) . Above a critical pulling speed, for a given temperature gradient and solute concentration, the interface, initially planar, breaks down into a periodic cellular pattern. The bifurcation from a planar to a cellular s...

Onset of sidebranching in directional solidification.

We use a computationally efficient phase-field formulation [B. Echebarria, Phys. Rev. E 70, 061604 (2004)] to investigate the origin and dynamics of sidebranching in directional solidification for realistic parameters of a dilute alloy previously studied experimentally [M. Gorgelin and A. Pocheau, Phys. Rev. E 57, 3189 (1998)]. Sidebranching is found to result either from noise amplification or...

Nucleation and Solidification of Silicon for Photovoltaics

The majority of solar cells produced today are made with crystalline silicon wafers, which are typically manufactured by growing a large piece of silicon and then sawing it into ~200 pm wafers, a process which converts one-half of the high-purity silicon into waste sawdust. To bypass the sawing process, a new method for making high-quality multicrystalline wafers without sawing is under develop...
