Bosch SolarEnergy announced that Bosch silicon cells have achieved a world record.The independent calibration laboratory at Fraunhofer Institute for Solar Energy Systems has confirmed that a degree of efficiency of 19.6percent has been reached for Bosch monocrystalline solar cells*. Normally, a silicon-based screen printed solar cell will achieveefficiencies of 17 to 18.5 percent. The output of the cells can reach an outstanding 4.73 Watt peak.
Bosch Solar Energy has been working on these new record-breaking cells for quite some time.The design structure on this new altered cell is referred to as PERCwhich stands for “Passivated Emitter and Rear Cell”. The rear side ofthe cell as well as the front was optimized for the solar cells’ optical and electrical properties.
An immediate practical application for these optimized cells is thatthe cell’s performance is improved under weak lighting conditions andincreased ambient temperatures. This means a higher energy yield forsolar consumers even during winter months or overcast days.
Most consumers are familiar with Bosch power tools or homeappliances. Installers and consumers alike should familiarize themselves with Bosch Solar. Founded in 1886, Bosch is a worldwide company and amarket leader in patents. If you have a twenty-five year warranty onyour solar panels you’ll want a company that you know will be around for a long time!
