Amorphous silicon degrades under illumination. In a solar cell, all three parameters—VOC, FF, and JSC—can be affected and usually decrease upon illumination. In intrinsic layers, the degradation affects the photoconductivity (which decreases), and the midgap density Do, which increases. The prope...
The dielectric function of thin‐film hydrogenated amorphous silicon (a‐Si:H) grown on fused silica at different substrate temperatures has been investigated by spectroscopic ellipsometry. An improved interpretation of the ellipsometric data is based on a tetrahedron model that takes into account the ...
The photogenerated carriers recombine non-radiatively in a time that can be as short as 1 ps at very large injected density ( N ≤ 10 21 cm 3 ). Several regimes are distinguished, depending on the value of N . In general, the characteristic times for all these processes are much shorter...
5.Thermal insulation materials, gas silicon has low thermal conductivity, which makes it have base thermal conductivity and excellent; 6.Adhesive sealant can be used as thickener and thixotropic agent to increase bonding strength and prevent sagging and collapse during fixe...
Hydrogenated amorphous silicon (a-Si:H) was prepared at a temperature of 460°C by thermal chemical vapour deposition (CVD) of silanes, generated by acid hydrolysis of magnesium silicide obtained from rice husk. Density of states (DOS) were determined from the capacitance-voltage relationships of...
The first part of this result involving the number N (or density) fluctuations is a purely geometrical result and does not involve any assumptions about thermal equilibrium or ergodicity and so is obeyed by all materials. From a large computer model of amorphous silicon, local number fluctuations...
It is proposed that hydrogen reactions near the growing surface control the structure of plasma-deposited amorphous silicon and its alloys. The model explains how the plasma influences the dangling bond density and silicon weak bond dist... Street,A R. - 《Mrs Online Proceeding Library Archive》...
solar cells/ electron trappingElectron deep-trapping mobility-lifetime (μτ) products were measured in a series of hydrogenated amorphous silicon (a-Si:H) specimens using the transient photocurrent charge-collection technique. A logarithmic dependence of the resulting μτ estimate upon the collection...
2.2.1 Amorphous silicon solar cells Amorphous silicon (a-Si) exists in a non-crystalline form of silicon, which can be deposited under benign conditions onto glass substrates. The discovery of hydrogenated a-Si (a-Si:H) showed much reduced defect density and improved photoconductivity, which lar...
