Nanoprobes for Future Generations of Photovoltaics

Research output: Contribution to conferencePaper


In this Solar Program Review Meeting, we report on our most recent progress in scanning probe microscopy (SPM) and its application to photovoltaics. We have developed an SPM to be operated in combination with a scanning electron microscope (SEM) JEOL5800. The SPM platform is compatible with a helium closed-circuit cryostat and fully accessible to the optics of the cathodoluminescence (CL)detectors with which the JEOL5800 is equipped. Among the innovative modes of operation that the combination --and synergy-- of SPM and electron microscopy provides, we describe (i) measurements of the lateral electron transport based on scanning tunneling microscopy (STM) and atomic force microscopy (AFM); (ii) scanning tunneling luminescence (STL); (iii) electroluminescence mapping; and (iv)near-field cathodoluminescence.
