Teaming black silicon and laser technologies, scientists at Natcore have created an all-low-temperature, laser-processed solar cell. According to the company, current silicon processing techniques involve temperatures of +850ºC or higher, but its device does not require temperatures above +350ºC for any process step. Since +350ºC is a common annealing temperature used in industry, the process requires no specialized equipment. For example, processing at +850ºC or higher is done in some form of a diffusion furnace, the interior of which needs to be fabricated from quartz or other very high-temperature compatible materials like silicon carbide. Natcore's process eliminates that diffusion furnace altogether.
