We refer to ultrathin solar cells as a 10-fold decrease in absorber thickness with respect to conventional solar cells, corresponding to thicknesses below 20 μm for c-Si and 400 nm for thin films such as GaAs, CdTe and CIGS. Numerous benefits are expected from thinner cells.
Nature Energy 5, 959–972 (2020) Cite this article Ultrathin solar cells with thicknesses at least 10 times lower than conventional solar cells could have the unique potential to efficiently convert solar energy into electricity while enabling material savings, shorter deposition times and improved carrier collection in defective absorber materials.
Prog. Photovolt. 22, 1023–1029 (2014). This work demonstrates an ultrathin CIGS solar cell (t = 385 nm) with a passivated back surface and nanosized point contacts (η = 13.5%). Vermang, B. et al. Introduction of Si PERC rear contacting design to boost efficiency of Cu (In, Ga)Se2 solar cells.
We believe that the advances in light trapping for ultrathin solar cells will also be beneficial to conventional (thicker) solar cells for further increase of Jsc, photon recycling and lower parasitic absorption losses. Photon management can also be used for thermal control of photovoltaic devices.

A key challenge for ultrathin solar cells is to enhance the light path in the cell to maintain a high absorption despite the thickness reduction. As discussed previously, submicrometre patterning is needed to scatter light or create multiple resonances in the absorber.
