Synthesis and Photovoltaic Application of Copper(I) Sulfide Nanocrystals

Abstract

We present the rational synthesis of colloidal copper(I) sulfide nanocrystals and demonstrate their application as an active light absorbing component in combination with CdS nanorods to make a solution-processed solar cell with 1.6% power conversion efficiency on both conventional glass substrates and flexible plastic substrates with stability over a 4 month testing period.

Enhancing the efficiency of SnS solar cells via band-offset engineering with a zinc oxysulfide buffer layer

“…1 Tin(II) sulfide (SnS) is among the ongoing investigated materials such as Cu 2 O, 2 Cu 2 S, 3 FeS 2 , 4,5 Cu 2 ZnSn(S x Se 1-x ) 4 , 6 and ZnSnP 2 . 7 SnS has a suitable bandgap (E g ~ 1.1 -1.5 eV), 8,9 strong optical absorption (α > 10 4 cm -1 ), 10 and proper carrier concentration ([p] ~ 10 14 -10 17 cm -3 ).…”

Photovoltaic Devices Employing Ternary PbSxSe1-x Nanocrystals

“…5,[7][8][9][10][11][12] With so many parameters to adjust in terms of size and shape, little work has focused on ternary or quaternary compositions of nanoparticles for solar cells. Yet it is well known from thin film solar cell studies that such compositional tuning can sometimes yield significant improvements in performance.…”

Electrochemical synthesis of nanoplatelets-like CuS0.2Se0.8 thin film for photoluminescence applications

“…IB -VIA is a very important group because CuS and CuSe thin films are useful in various fields, including nanoelectronics, nanophotonics, biotechnologies, also for energy storage and conversion [1]. Cadmium sulfide (CdS) and cadmium selenide (CdSe) belong to IIB-VIA group which is also very important because its band gap is in between the visible solar spectrum (1 to 3 eV) [2].…”
