Home > Press > Study Defines Expanded Purity Test Parameters for Photovoltaic Wafers

Abstract:
In a study of contaminant levels for silicon wafers utilized in photovoltaic applications, new test levels for purity reveal irradiation tests as the most comprehensive. The white paper, posted on ElementalAnalysis.com, discusses how Neutron Activation Analysis (NAA) exhibit accuracies up to parts per quadrillion.

Study Defines Expanded Purity Test Parameters for Photovoltaic Wafers

Lexington, KY | Posted on August 8th, 2007

Elemental Analysis Inc. , a privately held trace element analysis firm, today released a study which defines expanded silicon purity testing levels with applications to photovoltaic cells. The rise of nanotechnology and solar energy demand, combined with tight polysilicon supplies, require increasing purity testing levels for production.

The study reveals that irradiation testing of polysilicon cells can insure detection of contaminants to levels as sensitive as one part per quadrillion. Samples do not undergo pre-test irradiation.

The study provides test parameter data to aid silicon producers in evaluating the extended test application for industry production. By catching contamination early, companies can potentially reduce waste and improve production outputs.

Testing can turn around in as little as three days, speeding the process up substantially from current market wait times as long as three months.

Semiconductor, solar cell producers and nanotechnology firms are pushing for the highest accuracy test levels to insure purity of their products as they hit the markets.

"We can provide trace element testing to parts per quadrillion using our Neutron Activation Analysis techniques," states Mark Stauffer, of Elemental Analysis. "This 'ultra trace detection' capability enables our customers to take their products to market with full confidence that the purity levels required for performance are there."
