文摘

In this work, improved solar cells from aqueous CdTe NCs is achieved by replacing evaporated MoO_x with spiro-OMeTAD as a hole transfer layer. The increased V_oc and J_sc can be attributed to interfacial dipole effect and reduced back recombination loss, respectively. A high PCE of 6.56% for solar cells from aqueous NCs is obtained by optimizing the microstructure further.
