FAQs 6

Can gallium make solar panels more stable?

Research from our group at the University of New South Wales’s School of Photovoltaics and Renewable Energy Engineering shows that adding gallium to the cell’s silicon can lead to very stable solar panels which are much less susceptible to degrading over their lifetime.

What is the difference between gallium and boron-doped solar cells?

The boron-doped solar cell underwent significant degradation due to the boron bonding with oxygen. Meanwhile, the gallium-doped solar cell had a much higher voltage. Our result also demonstrated that p-type silicon made using gallium is very stable and could help unlock savings for this type of solar cell.

Could gallium be the answer to solar panels' biggest drawbacks?

Coming from a country where more than two million rooftops have solar panels, the Australian University of New South Wales has been exploring methods to reduce costs to the already cheapest form of electricity generation, and gallium may have given the answer to one of the solar panel's largest drawbacks.

Can gallium-doped solar wafers be integrated into existing cell and module lines?

Assuming that solar wafer manufacturers have overcome the technical challenges around gallium doping without a cost increase, and that the resistivity of the gallium-doped wafers is comparable to that of their boron-doped counterparts, the integration of gallium-doped wafers into existing cell and module lines should be quite straightforward.

Are solar panels boron or gallium?

But in May last year, the patents finally expired, allowing the industry to rapidly shift from boron to gallium. In fact, at the start of 2021, leading photovoltaic manufacturer Hanwha Q Cells estimated about 80% of all solar panels manufactured in 2021 used gallium doping rather than boron – a massive transition in such a short time!

Are BORon solar cells better than gallium solar cells?

In testing this process, the measured voltage of both boron- and gallium-doped solar cells during a light-soaking test for over three days showed that boron solar cells exhibited the traditional degradation, whereas the gallium solar cells maintained higher voltage and stability.
