Development of thin films by pulsed laser deposition for perovskite on silicon tandem solar cells

Abstract

Crystalline silicon solar cells dominate the PV market, yet their performances are now reaching their practical limit. One strategy to overcome this limit consists in producing tandem cells by associating a silicon sub-cell with another sub-cell with a wider bandgap perovskite absorber. Currently, the perovskite top-cell is deposited via solvent-based processes but one of the main research topics is the development of the different layers of the perovskite subcell via vacuum-based processes. Among the different techniques available, the PLD (Pulsed Laser Deposition) technique shows promising results. Indeed, while remaining at low temperature, large surface films of good crystalline quality could be obtained while maintaining a low ballistic impact so as not to degrade the underlying layers.

Thus this PhD will focus on the development and characterization of the different layers of the perovskite subcell by PLD. In particular, the development of lead-free inorganic perovskite layer by this process will be investigated as a non-toxic and manufacturable alternative to current hybrid materials.

This PhD will be carried out on the two sites of CEA-Grenoble and CEA-INES (located at Le Bourget du Lac).
