By comparison of polarization-type PID in the p-type and n-type c-Si cells with SiO 2 layers, we found that n-type cell degradation is greater and that it saturates in a shorter time than in the p-type cells.

The conversion efficiency of silicon heterojunction solar cells is limited by current losses mainly in the front layer stack. In order to minimize these losses, we implemented n-doped nanocrystalline silicon oxide (nc-SiOx:H) as front surface field to enhance both transparency and conductivity, thus improving the fill factor. Layers with …

In substrate-type configuration, the textures of n-i-p solar cells for light trapping are different from those of p-i-n solar cells in superstrate-type configuration. The substrate is usually coated with reflective metal such as silver or aluminum film, which acts as back electrode and reflector.
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy …
Passivating contacts based on thin tunneling oxides (SiOx) and n- and p-type semi-crystalline or polycrystalline silicon (poly-Si) enable high passivation quality and low contact resistivity, but the integration of these p+/n emitter and n+/n back surface field junctions into interdigitated back contact silicon solar cells poses a challenge due to high …
