| Description | Measurements were taken to determine the effects that solar cell processing steps have on the minority carrier lifetime in silicon. The experimental work included measurements of diffusion lengths of the silicon at various stages of cell fabrication, of solar cell properties, and of the PN junction properties for ingots covering a wide range of doping and other ingot properties. Resistivities covered the range of 0.01 to 10 ohm-cm, and combinations of extreme concentrations (high and low) of dislocations and oxygen were included. The results showed that the major cell process steps did not usually cause any appreciable change in diffusion lengths. The solar cell currents obtained supported the diffusion length measurements. The effects of heavy doping concentrations on solar cell performance were studied. Attempts were made to relate the voltage behavior of the cells with the diode properties and the properties of the ingots. |
