The wafers have a low Poisson’s ratio (0.28) 1, which indicates a high stiffness, and a high density (2.3 grams per cubic centimetre) 2. These features often make this type of solar cell brittle, heavy and fragile.
The work was partly supported by the U.S. Department of Energy, the Singapore-MIT Alliance for Research and Technology (SMART), and by a Total Energy Fellowship through the MIT Energy Initiative. A new analysis from MIT and NREL shows that making solar cells thinner could lead to cost savings and potentially avoid production bottlenecks.
That ultimately means cheaper power, and Li suggests that using the thinnest of the researchers’ cells could potentially shave 20% off the cost of solar electricity. Last year, Liu’s team in Shanghai made flexible cells with a 60 μm silicon wafer that offered efficiencies of more than 24% (Nature 2023, DOI: 10.1038/s41586-023-05921-z).
Although bendable cells can be made from thinner silicon wafers, they have lower efficiencies. Meanwhile, some thin-film solar cells —based on materials such as copper indium gallium selenide—are much more flexiblebecause they contain light-absorbing layers just 1 μm thick.
But, because of cost reductions that have already taken place in solar cell efficiency and other parts of the solar panel manufacturing process and supply chain, the cost of the silicon is once again a factor that can make a difference, he says. “Efficiency can only go up by a few percent.
The secret to success was to blunt the edges of the silicon wafers, thereby stopping them from undergoing brittle fracturing. As a result, the researchers were able to make 15-centimetre solar cells with a bending angle of more than 360°.
