Chemistry, Physics and Technology of Surface| Zusammenfassung: | Interesting direction of investigations is using surface-periodic structures in solar cells, because micrometer and nanometer periodic structures enlarge area of solar cells surface. At this, for using in solar cells, creation is proposed of p-n or n-p junctions in micro-threads of those structures. Taking into consideration that creation of those junctions is to be realized under a temperature impact, necessity arouses of analyzing temperature distribution in periodic structures through heating. It makes it possible to control the alloying process more widely and to create p-n or n-p junctions in micro-threads. In the process of thermal annealing of porous silicon, desorption of electrochemical processing products takes place on its surface and its luminescent properties change.In this work numerical calculations are made of a temperature distribution in periodic structures on silicon surface in process of thermal annealing.Calculations realized in the given investigation make it possible to forecast a temperature distribution in silicon periodic structures in process of thermal annealing. It gives a possibility for more precise alloying such structures. It is shown that after 40 µs the specimen gets warmed thoroughly. But a small irregular warming takes place between micro-threads that can be caused by heated air fluctuations. Distribution of the temperature profiles is shown at different time intervals.It is shown that in case of thermal annealing a span between micro-threads heats up. |
