Photo-voltaic solar cells achieve new levels of efficiency

01 June, 2004

Claimed to be the most efficient solar cells commercially produced in Europe are the Saturn 7 series of power modules from BP Solar. They have a low reverse-leakage current that improves low-light performance. Cell efficiency has been improved with a redesigned cell rear contact. Power tolerance is -0/+2.5%, and average power is above nominal power. Construction features include IntegraBus by-pass diode technology and external busbars. Reliability is improved by exponentially reducing the heat rise experienced by the modules when diodes are turned on due to cell shading. The new 72-cell Saturn 7 modules have six diodes, ensuring that less power is lost per module. The warranty covers power output for 25 years and freedom from defects for five years. saturn@bpsolar.com
