Abstract |
|
|
| Based on cadmium tellurium (CdTe), photovoltaic cells are designed to absorb and convert sunlight into electricity. In this paper, we tried to describe the underlying mechanisms of scattering ions from surface semichannel formed on the CdTe(001)<110>. When analyzing the calculated trajectories near the center of the semichannel, a special trajectory was discovered, which consists of two focuses - the first refers to ion focusing and is located near the bottom of the semichannel, the second refers to overfocused ions and is located near the surface. The effect of ion focusing is observed at small angles of incidence and the number of trajectories at this value of the angle of incidence is quite large. It is shown that with an increasing angle of ion bombardment, the number of trajectories that have two focus decreases and then disappears. The collision coefficient and energy of scattered ions are calculated. It was found that the collision coefficients and energies are very close to refocused ions.
