Plymouth, MA. - VPT announces a revolutionary new, cost-effective way to achieve large area thin-film uniformity.

For thin-film fabrication for precision optics, thickness uniformity is critical.  Traditionally, achieving the required degree of uniformity meant using shadow masks and planetary rotation—or a combination of the two. And that involved the time-consuming, labor-intensive process of cutting and re-cutting the mask until the desired uniformity was reached.

But VPT has invented a new kind of evaporation coater, with a breakthrough configuration they call Gyro Motion. Together with VPT’s computer simulation technology, Gyro Motion improves throughput, equipment utilization, yield—and gross margins—without masks or test runs.

Plymouth, MA. - VPT announces an innovative, cost-effective approach to manufacturing thin-film solar cells.

The demand for solar energy has never been greater. But for solar energy cells to be truly practical for general use, the cost has to come down and efficiency must go up.

Thin-film solar cells show great promise in both categories, but there have been obstacles. One in particular involves the high temperatures required to evaporate the materials used to coat solar cells. Traditionally, this has meant that special materials had to be used to construct the evaporation source and the chamber—and that meant added cost.

But VPT has changed all that, with a simple, low-cost alternative that uses commercially available materials. And brings us another step closer to truly affordable solar energy.
