Tainan, Taiwan — E-Ton Solar Tech. Co. announced the 3rd generation solar cell product line based on its newly developed “ExcelTonTM -Cell-III” technology. 6″ Mono ExcelTonTM -Cell-III adopts the 2nd generation PID-free technology (ExcelTonTM -Cell-II) with a rear-side passivation technology (Passivated Emitter Rear Contant, PERC), so that both the open circuit voltage (Voc) and short circuit current (Isc) of solar cell can be greatly improved.

As a result, the average conversion efficiency for the 6″ Mono cell can reach 20.2% level (with the best efficiency of 20.6%) in mass production.

ExcelTonTM -Cell-III with efficiency of 20.0% has been proven by customer of producing 60-cell solar module with peak output power of 280 Watts and higher.

This product mainly targets the application of 275-285 Watts high-power-output module. Another notable feature of this product is that it requires no additional equipment for rear-side deposition process, which can be easily implemented by upgrading the existing production tools with small modification, and pave the way for speedy expansion of the production capacity of PERC solar cell.

The company is now planning to expand the capacity of high-efficiency PERC cell from 60 MW to 120 MW by the end of 2015.
