Light Absorption Improvement in Nanostructured Backside Perovskite Quantum Dot Photovoltaics |
| 초록 |
CsPbI3 perovskite quantum dots (PQDs) are promising absorbers for solution-processed thin-film photovoltaics (PVs) due to their outstanding optoelectronic properties. However, CsPbI3 PQD PVs suffer from the low short-circuit current density (JSC) because of an insufficient light absorption within CsPbI3 PQD absorber. Introduction of nanostructured backside in CsPbI3 PQD PVs can improve the light absorption via enhancing the light trapping in CsPbI3 PQD absorber. Nanostructured spiro-OMeTAD hole-transport layer is fabricated using nanoimprint lithography method and subsequently deposited with MoOX/Ag comformally. The light absorption improvement via light trapping enhancement is demonstrated through the total absorption spectra and finite-difference time-domain simulation studies. The nanostructured backside in the CsPbI3 PQD PVs provides a high power conversion efficiency of 15.0% thanks to an increased JSC of 16.5 mA cm-2 obtained by light absorption improvement. |
