Al-doped ZnO mechanical milled powders for dye sensitized cells

Facile synthesis of ZnO nanobullets/nanoflakes and their applications to dye-sensitized solar cells

“…ZnO is an effective n-type semiconductor material, which has been explored in this field with great potential [33][34][35][36][37][38][39][40][41][42]. Recently, Zhang et al reported polydisperse ZnO aggregates based DSSCs, which achieved an overall energy conversion efficiency up to 5.4% [33,34].…”

Facile synthesis of highly oriented p-type aluminum co-doped zinc oxide film with aqua ammonia

“…The synthesis of a wide range of ZnO nanostructures has recently attracted considerable research interests (e.g., nanowires [2,3] and nanoflowers [4]). The potential applications of ZnO nanostructures include, solar cells [5,6], gas sensors [7][8][9], nanostructured transparent conductive oxide (TCO) [10] and bio-related applications [11]. The effective and reliable creation of the p-type ZnO plays a crucial part in the advancement of ZnO for optoelectronic device applications.…”

Surfactant and dopant addition effect on optical and structural properties of ZnSe (Te) nanostructured semiconductors

“…have proved this statement. In addition, solid state reaction techniques, like mechanical milling [18] have also been applied to obtained nanoparticles, quantum dots and doped semiconductors [8,10,[19][20][21][22]. However, one disadvantage of this synthesis method is particles agglomeration and cold-welding producing increase particle sizes during ball milling operations.…”
