Bosch Solar breaks world record with new cell design

May 5, 2011 § 6 Comments

Bosch Solar Energy 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 19.6 percent has been reached for Bosch monocrystalline solar cells*.  Normally, a silicon-based screen printed solar cell will achieve efficiencies of 17 to 18.5 percent. The output of the cells can reach an outstanding 4.73 Watt peak.

Bosch Solar Cells

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 PERC which stands for “Passivated Emitter and Rear Cell”.  The rear side of the 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 that the cell’s performance is improved under weak lighting conditions and increased ambient temperatures. This means a higher energy yield for solar consumers even during winter months or overcast days.

Most consumers are familiar with Bosch power tools or home appliances. Installers and consumers alike should familiarize themselves with Bosch Solar. Founded in 1886, Bosch is a worldwide company and a market leader in patents. If you have a twenty-five year warranty on your solar panels you’ll want a company that you know will be around for a long time!
