Effects of ZnSe or CdSe/ZnSe Core Shell Quantum Dots the Efficiency of Polymer Solar Cells. |
초록 |
Quantum dot (QD) solar cells have the potential capability to increase the maximum attainable thermodynamic conversion efficiency of solar photon conversion up to about 66% by utilizing hot photogenerated carriers to produce higher photovoltages or higher photocurrents. The former effect is based on miniband transport and collection of hot carriers in QD array photoelectrodes before they relax to the band edges through phonon emission. The latter effect is based on utilizing hot carriers in QD solar cells to generate and collect additional electronhole pairs through enhanced impact ionization processes. The most important process in all the QD solar cells for reaching very high conversion effciency is the multiple electronhole pair production in the photoexcited QDs. In this work, we ZnSe or CdSe/ZnSe core shell Quantum dots layer is employed is an electron transport layer in polymer solar cell. |
