In order to enhance the metal grid adhesion on silicon heterojunction (SHJ) solar cell, an acid etching treatment is applied onto indium tin oxide (ITO) layers before preparing Ag by screen printing. At same time, different annealing procedures ITO prior are comparatively investigated according variation of and SHJ cell performance. It found that can improve surface modifying roughness. However, corrosion degrade electrical optical properties layers. To mitigate this, process implemented...
A rear emitter with a p-type boron-doped hydrogenated amorphous silicon/nanocrystalline silicon [a-Si:H(p)/nc-Si:H(p)] stack was prepared for the heterojunction (SHJ) solar cell to improve its short-circuit current density (JSC). CO2 plasma treatment (CO2 PT) applied a-Si:H(p) facilitate crystallization of subsequently deposited nc-Si:H(p). To evaluate effect PT, two different nc-Si:H(p) layers low and high crystallinity (χC) were investigated. For (χC = 21%), efficiency could boost from...
Reducing the Cu(InxGa1−x)Se2 (CIGS) thickness is an effective way to reduce material use and increase manufacturing throughput. However, it still a challenge obtain high efficiency in ultrathin CIGS solar cell. Here, cell with 1.3 µm-thickness-CIGS was synthesized via three-stage co-evaporation method. The obtained cells were characterized by capacitance-voltage, capacitance-frequency, secondary ion mass spectrometry, X-ray fluorescence, transmission electron microscope, beam induced current...
Black silicon shows excellent anti-reflection and thus is extremely useful for photovoltaic applications. However, its high surface recombination velocity limits the efficiency of solar cells. In this paper, effective minority carrier lifetime black improved by optimizing metal-catalyzed chemical etching (MCCE) method, using an Al2O3 thin film deposited atomic layer deposition (ALD) as a passivation layer. Using spray method to eliminate impact on rear side, single-side was obtained n-type...
In future tokamak nuclear fusion devices, the development of suitable plasma facing materials is considered to be one great challenges. Liquid metal, instead conventional solid materials, has been proposed as a potential solution components (PFCs) for reactors, and it can solve problems that most reactors are facing. The splashing liquid metal into big problem because implementation PFCs in reactors. An experiment involving developed under strong magnetic field electric imitate interaction...
The SiOx(C)/SiNx dual-layer shows a better anti-reflection coating compared with standard SiNx films, after deposition and annealing. In this paper, the effect of film thickness, sintering peak temperature, belt speed, etc. on anti- reflectance SiOx(C) were discussed. Under optimized condition, weighted obtained 1.25% reduction; efficiency solar cell rises 0.35%. Sixty cells encapsulated modules gained 0.5 W larger power as well light stability than ones single layer.
On the basis of perfect PC2D simulation to measured current density vs voltage (J–V) curve best selective emitter (SE) solar cell fabricated by CSG Company using screen printing phosphoric paste method, we systematically investigated effect parameters gridline, base, emitter, back surface field (BSF) layer and recombination rate on performance SE cell. Among these parameters, identified that base minority carrier lifetime, front ratio sheet-resistance heavily lightly doped region are four...
This paper introduces a kind of field test system appraisal driver application in GPS technology inspection.Through two sets devices installed on the vehicle and difference base station established ground, contour coordinates outside movement state are get, comparing with specific area information to determine whether pressing line, get discretion pass exam or not.
Objective To explore the preventive effects of traditional chinese medicine education breast feeding on disease during lactation. Methods From October 2012 to 2013, a total 1 022 women who delivered at fourth Hospital shijiazhuang City were included in study.They divided into study group(n=512, with Chinese eduction) and control group(n=510, without education) according if they accepted school pregnant. The incidence rate postpartum galactostasis disease, cracked nipple mastitis...
Arrangement selected crystallization of different thickness from 100nm to 350nm amorphous silicon thin films on glass were prepared by 248nm wavelength UV excimer laser. A cleverly designed 5-dot-mask was used reshape the laser beam and sample placed scanned a XY-Axis translation stage with movement controlled programmable controller accurately in order optimize process conditions, kinds energies utilized. The laser-crystallized samples characterized Raman spectrometer, metallurgical...
