SolarWorld will be showcasing its exclusive new technologies to increase the efficiency of monocrystalline and polycrystalline PV modules at Intersolar Europe. The technology is able to increase the efficiency of modules by five to 10%. The modules will be available to customers by the second half of 2012.
Further, SolarWorld is showcasing the SunPac K 10.9 battery system, which offers integrated charging and discharging functions in a storage inverter. This system, too, can increase the efficiency of a PV system.
“Our researchers have managed to introduce a variety of new technologies into our automated solar cell production and combine them to create a better module while cutting costs,” Frank Asbeck, CEO of SolarWorld explained. “Three aspects played a role in improving the processes. First, SolarWorld is one of the world’s first manufacturers to significantly reduce the width of the electric conductor strips on the solar cells. Using an in-house technology, they achieve better results in comparison to industry standards of 80 to 90 micrometers. Second, SolarWorld uses a selective emitter on the front of the cell, which makes more light available for conversion into electricity. Finally, the back of the monocrystalline cell has been modified to increase electric conductivity.”
