Detailed analysis of radiative transitions from defects in n-type

We demonstrate our method on spatially non-uniform defects with radiative transitions in n -type monocrystalline silicon samples. It is shown that the defect PL originates from the donor-acceptor pair recombination mechanism, involving a shallow acceptor and deeper donor energy level.

N-type Silicon Solar Cells: The Future of Monocrystalline PV?

Phosphorus has one more electron than silicon, making the cell negatively charged (hence n-type). Though the first solar cell made in 1954 was n-type, p-type cells became the norm through their use by space agencies, as they are more resistant to degradation from cosmic rays. N-type cells can be more energy intensive to produce than p-type
