Back Contact Solar Panels

All back contact solar cells.

Back contact solar panels. This solar cell wraps the n emitter from the front to the rear surface through laser drilled holes to form conductive vias fig. Grape solar 100 watt monocrystalline flex panels utilize advanced technology back contact monocrystalline cells laminated into a flexible plastic sheet. Back contact technology allows you to get more efficient modules by limiting production costs so buying than standard forms. A promising back contact cell approach is the emitter wrap through ewt solar cell.

Grape solar 190 watt monocrystalline pv solar panel for cabins rv s and back up power systems model gs star 190w us 215 82 215 82. Back contact monosolar panels use special monocrystalline cells made by sunpower. These panels are about 50 more expensive than conventional mono but about 15 more efficient. Because of its high output per square foot it is ideal for tight spaces.

The back contact architecture was first realized with interdigitated back contact ibc silicon solar cells and is now widely employed in commercial c si solar cells with an efficiency of 21 achieved as early as 1985. Backcontact technology is the beginning of a new technological era for photovoltaics only present in the latest generation modules trienergia uses mwt metal wrap through with the electrodes in the back of the module pv. Silfab and dsm are concluding final testing to incorporate back contact cells and conductive backsheets into silfab s product lines. Back contact technology features all electrical contacts at the back of a solar cell thus creating maximum space on the front of the module to capture and convert more light into energy.

Ibc solar cells require interdigitated or striped doping on the rear surface and only have contacts on the rear. Set your store to see local availability add to cart. Back contact monocrystalline operating voltage. This doping can be achieved by masked diffusion masked ion implantation or laser doping.

The result is a panel far more rugged than the traditional glass and aluminum modules with the twice the efficiency approximately 20 of flexible thin film panels. The highest silicon wafer based solar cell power conversion efficiencies reported to date have been achieved with the interdigitated back contact ibc architecture.
