Solar cells, as we all know, generate energy by absorbing the sun’s rays. A good portion of the solar energy incident on these cells is reflected back, and as such not used in the generation of power. So, solar cells could be made more efficient at creating electricity from incident light. Another method to increase the efficiency would require making the manufacturing process cheaper. Sixtron Advanced Materials, a company based in Montreal, claims to have created a new process that could do both the jobs listed above.
The company’s new antireflective coating for crystalline solar cells could make manufacturing solar cells cheaper by doing away with the requirement of silane gas. This gas is toxic, highly inflammable and as such requires special storage, ventilation, and other safety measures. Sixtron’s process uses Silexium, thus allowing manufacturers to steer clear of the costs and risks associated with silane gas.
This Silexium coating also reduces light-induced degradation by up to 88 percent, resulting in greater efficiency over the life term of the solar cells.
