6 FAQs about [Photovoltaic cell dephosphorized silicon glass]

Can silicon reduce potential induced degradation of crystalline Si solar cells?

This study proposes a promising silicon (Si) solar cell structure for reducing the potential induced degradation (PID) of crystalline Si solar cells. Phosphorous silicate glass (PSG) layers were carefully designed on an emitter layer, and the thickness of these layers (d PSG) was controlled by adjusting the diffusion temperature and time.

How do phosphorus silicate glass layers affect PV efficiencies?

Phosphorous silicate glass (PSG) layers were carefully designed on an emitter layer to determine how they affect the efficiencies of solar cells before and after PID. A current-voltage (I-V) tester was used to determine PV parameters. An ellipseometer and transmission electron microscope (TEM) were used to measure the thicknesses of the PSG layers.

What is the phosphosilicate glass layer?

Commonly, the dopant source grown on the silicon surface during the deposition step of POCl 3 diffusions is referred to as the phosphosilicate glass (PSG) layer. Actually, the PSG layer is separated from the silicon surface by a thin silicon dioxide (SiO 2 ) layer featuring a much lower phosphorus concentration [2].

What is phosphosilicate glass (PSG)?

The phosphosilicate glass (PSG), fabricated by tube furnace diffusion using a POCl3 source, is widely used as a dopant source in the manufacturing of crystalline silicon solar cells.

Where is phosphosilicate glass used?

Is phosphosilicate glass deposited under SiO2 doping conditions?

We measure concentration profiles within the deposited phosphosilicate glass (PSG) layer for a range of POCl3 doping conditions and find that (i) its composition is nearly independent of process conditions and (ii) it is separated from Si by a thin SiO2 layer. We also find strong accumulation of P at the SiO2-Si interface.
