6 FAQs about [Photovoltaic panel laser doping process]

Can laser doping damage a solar cell?

However, laser-induced damage must be avoided in order to achieve high solar cell efficiencies. For commercial applications, it is also important to have a laser doping process with a high throughput of one wafer per second, which is the standard in the photovoltaic industry.

Can laser doping be used in PV metallization?

Laser doping conditions such as focus, power and speed should be carefully selected. Different plating strategies may need for different laser resources doped samples. Plating has long been recognized as a promising alternative to screen printing in commercial PV metallization due to its cost-saving and scaling-up potential.

Can laser doping be used in crystalline silicon solar cells?

Engelhardt et al. ( 2019) have demonstrated laser doping from as-deposited CVD layers for high-efficiency crystalline silicon solar cells where an open-circuit voltage of 700 mV was attained, enabling an overall conversion efficiency of >22.5% (Engelhardt et al. 2019 ).

Does laser doping affect plated contact formation?

Nevertheless, the results from this study reveal the potential effects of laser doping conditions on plated contact formation and indicate that key parameters should be carefully selected and optimized, which could be very helpful for those fabricating plated contacts through LD patterning. Fig. 12.

What is laser doping?

This method is often referred as laser doping (LD), which is based on the laser doped selective emitters (LDSE) technology developed at UNSW in 2007. It involves four processes: (1) melting of Si; (2) removal of dielectric layers; (3) diffusion of dopants; and (4) recrystallisation of molten Si. The entire process occurs in less than 1 μs [16 ].
