Objective
The general foal of this research is the preparation and characterisation of shallow P/N junctions realized by coupling non-analyzed ion implantation of the dopant (developed by PHASE laboratory) or any kind of deposition techniques with a special transient optical heating technique (developed by FhG-ISE) which can operate in the liquid and solid phase regime.
Research has been carried out with respect to the preparation and characterization of shallow P/N junctions realized by coupling nonanalyzed ion implantation of the dopant (or any kind of deposition technique) with a special transient optical heating technique which can operate in the liquid and solid phase regime.
Research was carried out in the following areas:
doping procedures (doped silicon presses);
transient annealing (rapid thermal processing in lamp furnaces);
characterization of the junction;
crossing comparison of the techniques;
solar cell manufacturing (15% efficiency for a single P/N junction).
Perspectives of a dry processing are being investigated in a new project.
The best result of this research was the realization of 15% conversion efficiency P/N junction silicon solar cells by employing a doping using doped silicon glasses to rapid thermal diffusion in a lamp furnace.
