TEM characterization of advanced kesterite structures

In the present work, we study a kesterite Cu2ZnSnSe4 solar cell at the nanoscale level in order to analyze the defects that lower its energy conversion efficiency. First of all, current density{voltage characteristics, quan- tum effciency, photoluminiscence, and Raman spectroscopy are studied to obtain macroscopic and microscopic information about the device. Then, High Resolution Transmission Electron Microscopy (HRTEM) is performed to observe the cross-section and, for the first time, the front interface of the absorber with nanoscopic detail
