SOITEC’s 4 junction solar cell module one year on sun

During the last years SOITEC has co-developed a 4-junction solar cell (SmartCell™) with world record conversion efficiency. To verify suitability for concentrator application in SOITEC’s Concentrix™ CPV module, early long-term outdoor performance monitoring was initiated. To date, some module prototypes have been already exposed for more than one year in desert environment; no performance degradation is observable. Accelerated ageing testing executed on the cells also indicates comparable reliability performance to standard triple junction concentrator solar cells.
