NSP's "Perfect Cell" Said To Harvest More Solar Energy

Hsinchu, Taiwan [RenewableEnergyWorld.com] Taiwanese solar cell manufacturer Neo Solar Power (NSP) announced at Solar Power International 2009 that it has begun production shipment of 156mm full-square mono-crystalline solar cells, named "Perfect Cell."

The company says that traditionally 156mm mono-crystalline solar cells are manufactured on “pseudo-square” wafers with the corners being cut off. The cut-off corners result in a smaller area from which solar panels can capture sunlight.

Because they are perfect squares, NSP perfect cells offer panel-makers the ability to increase a panel’s active area by more than 3%, says the company, and thus increase the module efficiency. The company claims that on a 60-cell panel manufactured with NSP’s Perfect Cell, panel output can exceed 250W while traditional mono- or multi-cell modules are around 220W.

NSP says that its Perfect Cell has an average of 17.8% conversion efficiency and has extremely low LID (Light Induced Degradation), and a homogeneous dark appearance making it a “perfect choice” for system integrators to serve in both roof-top installations and BIPV applications.
