6 FAQs about [Photovoltaic high boron glass]

How does boron affect photovoltaic cells?

Boron can be added as an antireflection coating on top of the photovoltaic cell surface, increasing its reflectivity – which reduces losses from incident sunlight that doesn’t pass through – or mixed in when manufacturing solar cells themselves so that they include boron atoms within their crystalline structure instead of just on top.

What is high-temperature boron doping?

Times for the high-temperature process are equivalent to those for a traditional homogenous emitter. The innovative thermal pre-diffusion process created a unique boron doping profile, achieving a high surface concentration of nearly 1 × 10 20 cm −3 with a shallow junction depth of approximately 0.25 μm.

How does laser treatment affect boron diffusion?

Laser treatment further activated boron and facilitated its diffusion, influenced by the boron silicate glass layer and surface boron atoms. Adjustments were made to improve the pre-diffusion recipe, including an additional boron deposition step, increasing non-activated boron atoms.
