The company claimed that due to its mono-PERC processes the Black 21 cell had reduced light-induced degradation (LID) that was lower than that of normal p-mono cells. The cell was also claimed to have to also have a low potential-induced degradation (PID). 

NSP expects the product to be available for engineering sampling at the end of 2015.
