In typical process, the precursor materials are printed or sputtered onto surface, where they combine to form the final semiconductor material.

Thinfilm solar cells are attractive because they could produce electricity cheaper than conventional silicon solar cells.

In the Heliovolt process, which Stanbery developed, the semiconductor is made in two steps.
Advertise For example, generating one watt of electricity requires about cents worth of silicon, but it only requires pennys worth of semiconductor used in thinfilm cell, says John Benner, who manages electronic materials for photovoltaics research at the National Renewable Energy Laboratory NREL, in Golden, CO.

But, while no one expects to reach this level of efficiency needed to compete with other types of solar cells. Having too few selenium atoms can kill cell, says Heliovolts CEO, Billy Stanbery.
Thinfilm solar cells are attractive because they could produce electricity cheaper than conventional silicon solar cells do, they make up for this by using orders of magnitude less active material per square meter. Heliovolt is working with NREL to further develop its cells. The challenge has been to reliably make thinfilm solar cells more reliably than other methods.
