Madrid, Spain Isofoton has used the 25th European Photovoltaic Solar Energy Conference (EUPVSEC) to launch a high-concentration PV that it hopes will earn it a place among the top suppliers of high concentration systems.
Generating 200 W/m² DC electrical power, the GEN2 offers an improved efficiency and lower production cost that enable it to compete with conventional photovoltaic technology, according to the Spanish company.
The GEN2 concentrates light from the sun through two-stage optics using a triple-layer solar cell based on semiconductor materials other than silicon. This leads to greater efficiencies and an effective use of the solar spectrum, says Isofoton.
The technological development of GEN2 represents a reduction of the costs of the production process through improving the materials used and combining them more efficiently, the company reports.
The firm’s GEN2’s technology has been development since 2001, according to Isofoton, which was a founder member of the CPV Consortium. The company participates in the Institute of Concentration Photovoltaic Systems (ISFOC) project, which is both a a municipal power plant and a proving ground for CPV technology.
