Both n-type cell concepts – IBC as well as PERL – have the benefit of high cell efficiency. There is no Light Induced Degradation (LID) leading to severe performance degradation. Moreover, high open-circuit voltages (VOC) of these cell types result in excellent temperature coefficients.


Obstacles to be overcome in production are high costs of n-type wafers and complex cell processing. Critical to this end are cost-effective diffusion processes. Several research institutes apply APCVD systems from SCHMID to develop cost-effective mass production processes for n-type cells.
