Tuning the plasmonic absorption of metal reflectors by zinc oxide nano particles: Application in thin film solar cells

Analytical Modeling of the Light-to-Heat Conversion by Nanoparticle Ensemble under Radiation Action

“…If the condition t / τ 01 << 1 is obeyed and the loss of heat from a NP by heat conduction during the time t can be ignored, we find from expression (25) The parameters P 2 , P 3 for heat exchange between NPs and medium are presented from (9,29,30) …”

“…INTRODUCTION In recent years the absorption of radiation energy by NPs, light-to-heat conversion, heat dissipation and exchange with a surrounding material (medium), and following thermal and accompanied phenomena have become increasingly important topics in nanotechnology . Many reasons exist for this interest, including the applications of the light-to-heat conversion in nanoenergy [1][2][3][4][5][6][7][8][9][10][11][12], in photothermal laser nanomedicine [13][14][15][16] and catalysis [17,18], in laser processing of NPs (laser induced transformation of NP size, shape and structure) [19][20][21][22][23][24], etc. These advances in nanotechnology are based on the efficiency of light-to-heat conversion, thermal effects and the processes induced by the laser-NP interaction [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…Theoretical investigation of the light-to-heat conversion under action of radiation on NPs [1][2][3][4][5][6][7][8][9][10][11][12] is predominantly based on the description of the processes with single NP. The light-to-heat conversion with NP ensemble practically did not investigate and only a few general equations were formulated and the estimations were made.…”

Aluminum–Titanium Alloy Back Contact Reducing Production Cost of Silicon Thin-Film Solar Cells

“…To achieve silicon thin-film solar cells with high short circuit currents and conversion efficiencies, the incident light has to be efficiently scattered and diffracted. Conventional solar cells normally achieve light trapping with three methods, a textured front surface, a highly reflective rear reflector and an antireflection coating [4][5][6]. Silver (Ag) is the conventional metal for back reflectors, but its drawbacks are high price, low adhesion and agglomeration behavior [7][8][9].…”

Characteristics of vented nano-polymethyl methacrylate dust explosions

“…Nano-materials are widely used in the field of high-density magnetic recording materials, microchip heat conductive substrates and their wiring materials, solar cell materials, high toughness ceramic materials, catalyst materials and body repair materials [1][2][3]; therefore, it is important to seriously consider accidental nano-dust explosions. Compared with micro-materials, nano-materials exhibit smaller particle size, larger specific surface area, higher surface energy and larger proportion of surface atoms, which lead to higher potential explosion severity for nano-dusts.…”
