What is a PSG layer in a solar cell?

SIMS was performed to analysis the migration of sodium ions in the solar cells. A PSG layer can be formed on a Si surface during the phosphorous diffusion process according the following reactions: 11 The PSG layer is a mixture of P 2 O 5 and SiO 2, which can be easily removed by using a HF solution.

What is phosphosilicate glass (PSG) layer system?

The phosphosilicate glass (PSG) layer system grown on the silicon surface during diffusion processes with phosphorus oxychloride (POCl 3) is a two-layer stack system consisting of a PSG and a silicon dioxide (SiO 2) layer. Understanding the stack layers’ structure and composition is essential for further optimizing POCl 3 diffusion processes.

Do PSG layers affect Si solar cells after PID treatment?

The PSG layer is a mixture of P 2 O 5 and SiO 2, which can be easily removed by using a HF solution.
