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.
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.
In the diffusion process, a glass, known as phosphosilicate glass, of phosphorus pentaoxide (P 2 O 5 ) and silicon dioxide (SiO 2 ) are formed due to the uncontrolled amount of dopant and irregular diffusion at the silicon surface.
Metallic impurities are one of the main recombination losses in silicon substrates, leading to a decrease in the PCE of solar cells [, , ]. Phosphorus diffusion gettering (PDG) has been most widely used in silicon photovoltaic technology due to its high capture efficiency and metal mobility at high temperatures [, , , ].
The diffusion of phosphorus mediated by phosphorus oxychloride (POCl_3) is extensively used in photovoltaics due to its enhanced diffusion speed and to the high controllability of the phosphorus at the wafer surface.
