But some other elements are also required. 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.
As gallium is used more and more to achieve this, our findings provide robust data that could allow manufacturers to make decisions that will ultimately have a global impact. A solar cell converts sunlight into electricity by using the energy from sunlight to “break away” negative charges, or electrons, in the silicon.
As widely-available silicon solar cells, the development of GaAs-based solar cells has been ongoing for many years. Although cells on the gallium arsenide basis today achieve the highest efficiency of all, they are not very widespread. They have particular specifications that make them attractive, especially for certain areas.
Unfortunately, this means the sunlight that powers solar panels also damages them over their lifetime. An element called gallium looks like it could be the solution to this problem.
German scientists have conducted a series of experiments on gallium-doped silicon solar cells to understand the causes of degradation in PV cells and modules treated with gallium rather than boron.
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!
The first Gallium Arsenide (GaAs) thin-film solar panel was made by Zhores Alferov and his students in 1970. The team persisted to create the gallium arsenide semiconductor, until they made a breakthrough in 1967, three years later they created the first gallium arsenide (GaAs) solar cell.

Does gallium really boost solar panel stability? We investigated whether solar cells made with gallium-doped silicon really are more stable than solar cells made with boron-doped silicon. To find out, we made solar cells using a "silicon heterojunction" design, which is the approach that has led to the highest efficiency silicon solar cells to
German scientists have conducted a series of experiments on gallium-doped silicon solar cells to understand the causes of degradation in PV cells and modules treated with gallium rather than boron.
