This means that the parasitic bipolar base is at zero volts( for latch up), the … Webn- and p-type wafers, and the non-wafer costs of producing the SHJ cells. Given the most up-to-date expected values for the difference in n- and p-type wafer costs and the cost of cell fabrication, p-type SHJ cells need to obtain efficiency values within 0.4–0.5% abs of that of n-type SHJ cells to be economically advantageous.
