Synthesis and layering of Si quantum dots/SiO2 composite films for third generation solar cells

4nm silicon quantum dots (Si-QDs) produced by laser pyrolysis have been embedded in a SiO2 matrix using sol–gel process. The nanocomposite layers exhibit promising properties for third generation solar cell application. High resolution transmission electron microscopy observations show that the part...

Zusammenfassung:4nm silicon quantum dots (Si-QDs) produced by laser pyrolysis have been embedded in a SiO2 matrix using sol–gel process. The nanocomposite layers exhibit promising properties for third generation solar cell application. High resolution transmission electron microscopy observations show that the particles are well dispersed in the matrix, and separated by a short distance (
