Novel Concentrating Nanoscale Solar Cells
APPLICATION OF TECHNOLOGY:
Nanoscale solar cells ADVANTAGES:
Multi-junction absorption efficiencies with easier fabrication Promises simpler installation than conventional cell/concentrator combinations Can be flexible
Researchers at Berkeley Lab are using photonic principles to develop solar cell/concentrator devices. The nanoscale cells take advantage of the fact that a solar cell’s efficiency increases under concentrated light. The materials can be tailored to absorb light at a wide range of energies, creating a multi-gap device without expensive multi-junction processing.
The materials necessary to make these thin-film cells are less expensive than conventional solar cell materials. In addition, the innovative solar cell/concentrator construction will offer simpler installation, and possibly enable small and even residential photovoltaic projects to exploit the advantages of the concentrator concept.
