Comparison of time stability between iodine/ethanol and quinhydrone/methanol solution for chemical passivation of a silicon surface for minority carrier bulk-lifetime measurements
Original language description
Monitoring of the carrier bulk-lifetime is necessary for modifying the whole technological process of solar cells production. This work deals with an examination of a different solution types for the chemical passivation of a silicon surface for minoritycarrier bulk-lifetime measurements. For the measurement of the minority carrier bulk-lifetime is used characterization method MW PCD (Microwave Photoconductance Decay), where result of measurement is effective carrier life time, which is very dependenton the surface recombination velocity therefore on the quality of a silicon surface passivation. The main purpose of this work is to compare time stability of iodine/ethanol and quinhydrone/methanol solution. Another purpose of this work is to identify the parameters of other quinhydrone solutions with different concetrations as compared with the quinhydrone solution in methanol with a concentration of 0.07 mol/dm? marked QM007 (referential solution). It is important to identify the infl
