Nanocrystal photovoltaics: a review of recent progress

1/f noise in semiconductor and metal nanocrystal solids

“…In nanocrystal systems, 1/f noise has already been shown to limit the sensitivity of chemoresistive sensors based on metal nanoparticles, 8 while with colloidal quantum dot infrared photodetectors, the 1/f noise is a limitation for the detectivity. 9,10 As new materials based on nanocrystal assemblies are being developed for many applications, [11][12][13] this investigation aimed to characterize the 1/f noise in various nanocrystals systems.…”

Excited-State Dynamics in Colloidal Semiconductor Nanocrystals

“…An attractive feature of colloidal semiconductor NCs and hetero-NCs is that they can be used as solution-processable building blocks for nanostructured thin-films, either by directly depositing the colloidal suspension of NCs or hetero-NCs (the socalled NC inks) onto a substrate and evaporating the solvent [20,23], or by allowing the NCs or hetero-NCs to self-organize into long-range three-or two-dimensionally ordered superlattices at air-liquid interfaces and subsequently transferring the superstructure to a suitable substrate [129,130]. Colloidal NCs can also selfassemble into three-dimensionally ordered colloidal superparticles [131].…”

“…Since the pioneering work of Brus, Ekimov, and many others in the early 1980-1990s [1][2][3][4][5][6][7][8][9][10][11][12][13], the study of semiconductor nanocrystals (NCs) has developed into a mature, dynamic and multidisciplinary research field, which attracts increasing attention worldwide, both for its fundamental challenges and its potential for a number of technologies (light emitting devices, solar cells, luminescent solar concentrators, optoelectronics, sensing, thermoelectrics, biomedical applications, catalysis) [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Colloidal semiconductor NCs are particularly attractive, since they consist of an inorganic core that is coated with a stabilizing layer of (usually) organic ligand molecules.…”

CuInSe₂ (CIS) as A light Absorption Layer of Photovoltaic Solar-Cells

“…Arrested precipitation has been a particularly effective way to obtain nanocrystals with a wide range of compositions and tunable sizes and shapes Stolle et al, 2013 Oleylamine was degassed by pulling vacuum overnight at ∼200 mTorr at 110°C and stored in an N 2 filled glovebox before use. All other chemicals were used as received without further purification.…”
