Silicon Growth Technologies for PV Applications

2016/10/10The growth of a Cz silicon crystal starts with the stacking of high purity polysilicon feedstock in the crucible, where either solar-grade or electronic grade silicon are normally used. The silicon chunks are placed strategically in order to (1) avoid movements during subsequent feedstock melting and (2) minimize the contact between the crucible and the silicon to limit the incorporation of

Hot spots in multicrystalline silicon solar cells:

Multicrystalline silicon solar cells typically show hard breakdown beginning from about –13 V bias, which leads to the well‐known hot‐spot problem. Using special lock‐in thermography techniques, hard breakdown has been found to occur in regions of avalanche multiplication.

Effect of oxide thickness on the low temperature (lt;=400

Au-catalyzed cone-shaped silicon nanowires (CSiNWs) were grown at low temperature (≤400 C) using plasma-enhanced chemical vapor deposition (PECVD). Thin (≤3 nm) Au films were evaporated and annealed on a thermally oxidized (0-80 nm) silicon substrate so as to form Au silicides, which, under a supply of SiH4, catalyzed the growth of CSiNWs. We have found that the thickness of thermally
