Highly efficient silicon solar cells that are as flexible as a sheet of paper could offer a lightweight power source for applications such as uncrewed aerial vehicles while cutting the cost of solar panels on the ground (Nature 2024, DOI: 10.1038/s41586-023-06948-y).
Wow, pas mal cette performance de 26.06% !
The consortium behind the new cells includes researchers from Chinese company LONGi, one of the world’s leading solar manufacturers, and universities in China and Australia. The team made a series of 274.4 cm2 cells—a standard commercial size—with silicon wafer thicknesses ranging from 57 to 125 μm. Each cell set a new efficiency record for a wafer of its particular thickness: even the 57 μm cell managed to convert 26.06% of light energy into electricity, a result described as “very impressive” by PV researcher Wenzhu Liu at the Shanghai Institute of Microsystem and Information Technology who was not involved in the work.
