New Solar Module Uses Holographic Foil to Create Cheaper, More Efficient Panels

by Lidija Grozdanic, 01/31/13

A new silicon-based solar panel which utilizes holographic foil is reported to be nearly twice as efficient as standard panels. Referred to as a “game-changing technology,” the panels were developed by the Dresden-based Apollon GmbH&Co.KG and Solar Bankers LLC from Arizona. The technology is based on holographic optics which allow the new solar modules to be manufactured at a much lower cost than conventional solar panels.

The system can achieve 28 percent efficiency, which is significantly higher than the average 17 efficiency of currently used solar panels, according to the company. The holographic foil is printed on the cover glass and filters the sunlight. The distance between optic and solar cell is only a few millimeters and filters only the desirable wavelengths of the light. The sunlight is then concentrated on the solar cells, preventing significant energy losses. Thanks to the printing process, modules can be cheaply duplicated, thus saving time and resources.
