Description: 
Silicon nanocrystals (Si NCs) embedded in Si-based dielectrics provide a Si-based high-bandgap material (1.7 eV) and enable the construction of crystalline Si tandem solar cells. This chapter focusses on Si NC embedded in silicon carbide, because silicon carbide offers electrical conduction through the matrix material. The material development is reviewed, and optical modeling is introduced as a powerful method to monitor the four material components, amorphous and crystalline silicon as well as amorphous and crystalline silicon carbide. In the second part of this chapter, recent device developments for the photovoltaic characterization of Si NCs are examined. The controlled growth of Si NCs involves high-temperature annealing which deteriorates the properties of any previously established selective contacts. A membrane-based device is presented to overcome these limitations. In this approach, the …
