This Is Natcore Technology Scientific Discipline Aims To Hit Solar Cells Without Using Precious Silverish Metal
Natcore Technology aims to supplant the traditional thermal vacuum processes, such every bit CVD in addition to PECVD (chemical vapor deposition, plasma enhanced chemic vapor deposition, etc.) for making solar cells amongst their liquid stage deposition (LPD) moisture chemical scientific discipline process.

When Natcore Technology Inc. announced the evolution of a breakthrough solar prison theater cellphone construction on July 9, they indicated that the novel low-cost configuration mightiness permit for the elimination of argent from mass-produced solar cells.
When sunlight hits a silicon cell, it generates electrons. Ever since practical solar cells accept been made – nearly threescore years agone – argent has been used every bit a conductor to collect these electrons inwards club to shape a useful electrical current. Silver was originally chosen for this component subdivision because it is a high-conductivity metal. The average solar panel uses nearly half of an ounce of silver.

Silver represents >48% of the metallization cost of a solar cell, or nearly 11% of the total raw textile cost of a solar module. The cost saving realized past times switching from argent to aluminum are important. That’s because silver, piece highly conductive, is likewise high-cost. At today’s prices, argent costs nearly $15.28 per troy ounce. The same quantity of aluminum costs $0.05, nearly 0.3% of the cost of silver.
Even considering that it would hold out necessary to piece of occupation twice every bit much aluminum every bit argent inwards club to accept an equal total of electrical conductivity from prison theater cellphone to cell, the raw textile cost of aluminum would even then hold out only 0.6% of the straight textile cost of using argent inwards the cell. Natcore’s novel blueprint allows for aluminum to hold out easily substituted for silver. Natcore scientists used their proprietary Light Amplification by Stimulated Emission of Radiation applied scientific discipline to apply contacts to the nurture of the prison theater cellphone every bit good every bit for other critical aspects of the process.
“Within the past times month, our scientists accept wrought historic changes inwards the architecture in addition to the economic science of the solar cell,” says Chuck Provini, Natcore president in addition to CEO. “Solar prison theater cellphone manufacturers volition no longer hold out discipline to the vagaries of the argent market. We are right away able to hit solar cells at a substantial cost savings thank y'all to improvements achievable past times our proprietary Light Amplification by Stimulated Emission of Radiation technology. We facial expression to file a provisional patent application inside the side past times side 2 weeks.”
Roughly 1.5 ane chiliad 1000 ounces of argent are currently required to generate 1 GW of solar power. That need translated into some threescore ane chiliad 1000 ounces of argent inwards 2014, or nearly 6% of the total need for the metal. Before Natcore’s achievement, that need was projected to rising to 15% of the total marketplace inwards 2018. (Source:Natcoresolar)
