Silicon Ink Is Spot On, NREL Experiments Show

Speed and Precision Keys to Large-scale Manufacturing of Solar Cells When you're making millions of solar cells a week, the process has to be a combination of precision and speed. That means there has to be a fast way to deposit lightly-doped silicon here while depositing heavily-doped silicon there. Innovalight's ability to make their Silicon Ink emulsion liquid, without having solids clump together or fall to the bottom made their product a potential game-changer. The aim is to moderately dope the emitter between the front grid lines such that most of the sun's light is absorbed in the solar cell's lightly-doped base, while heavy doping in the emitter precisely under the grid lines reduces contact series resistance. The result is a more efficient solar cell, which means smaller modules can generate the same amount of power. And that means lower costs for the consumer, wh...
