Polarized electroabsorption spectra and light soaking of solar cells based on hydrogenated amorphous silicon
نویسندگان
چکیده
We present grazing-incidence measurements of polarized electroabsorption spectra in p – i – n solar cells based on hydrogenated amorphous silicon (a-Si:H!. We find a significantly stronger polarization dependence in the present measurements compared with earlier work based on electroabsorption detected using coplanar electrodes on a-Si:H thin films. We do not find any significant dependence of the polarized electroabsorption upon light soaking, although this effect was found in previous work with coplanar electrodes. © 1998 American Institute of Physics. @S0003-6951~98!01909-3#

Temperature-Dependent Open-Circuit Voltage Measurements and Light-Soaking in Hydrogenated Amorphous Silcon Solar Cells
We present temperature-dependent measurements of the open-circuit voltage VOC(T) in hydrogenated amorphous silicon nip solar cells prepared at United Solar. At room-temperature and above, VOC measured using near-solar illumination intensity differs by as much as 0.04 V for the as-deposited and light-soaked states; the values of VOC for the two states converge below 250 K. Models for VOC based e...
متن کاملData supporting the role of electric field and electrode material on the improvement of the ageing effects in hydrogenated amorphous silicon solar cells
Hydrogenated amorphous Si (a-Si:H) solar cells are strongly affected by the well known Staebler-Wronski effect. This is a worsening of solar cell performances under light soaking which results in a substantial loss of cell power conversion efficiency compared to time zero performance. It is believed not to be an extrinsic effect, but rather a basic phenomenon related to the nature of a-Si:H and...
متن کاملParameter Estimation and Modeling of Hydrogenated Amorphous Silicon
The use of hydrogenated amorphous silicon material(a-Si:H) in devices such as solar cells, active thin film transistor liquid crystal display panels, various sensors, etc. requires an accurate model of the material characteristics and their dependence on light intensity and light soaking over a broad temperature range. Through the use of nonlinear parameter estimation techniques, a gap state mo...

Hydrogenated amorphous silicon-germanium (aSiGe:H) films and n-i-p solar cells near the threshold of microcrystalline formation have been prepared by plasma enhanced chemical vapor deposition (PECVD) with a fixed germane to disilane ratio of 0.72 and a wide range of hydrogen dilution RH=(H2 flow)/(GeH4+Si2H6 flow) values of 1.7, 10, 30, 50, 120, 180 and 240. The effects of RH on the structural ...
متن کاملElectron drift mobility measurements on annealed and light-soaked hydrogenated amorphous silicon
We measured the effects of light soaking on the electron drift mobility for three specimens of hydrogenated amorphous silicon (a-Si:H) from different laboratories. The temperature range 130-300 K was studied. The measurements in all cases reveal two temporal regimes: an early time regime associated with bandtail transport, and a later-time regime associated with deep trapping of the electrons. ...
