Vacuum deposition methods for perovskite-silicon tandem solar cells


Project Description

Perovskite-silicon tandem solar cells are a very promising technology for harvesting the energy of sunlight. Perovskite-silicon tandem solar cells can theoretically achieve power conversion efficiencies in excess of 30%, which is higher than that of single-junction perovskite or silicon solar cells.

This project concerns the development perovskite-silicon tandem solar cells based on double-side-textured c-Si wafers.  The student will work on the fabrication of such cells and the study of deposition methods that are scalable and conformal with a high degree of uniformity and reproducibility. The student will work with various vacuum based techniques, such as thermal evaporation and ALD, for the deposition hole-transport (HTL) and electron transport layers (ETL), with the aim of developing precursors for all-vacuum-evaporation deposition protocols of large scale and highly efficient tandem solar cells.
