In this experiment,we used the solvothermal method that described by Y.Qian et al,to synthesize nano powder which have different morphology.We had demonstrated it that by controlling and changing the temperature,reaction time and washing agents,to control the size and it leads to the change of the energy gap.In others,we changed the ,and used the same method to synthesize CuGaSe2 powder.It was used to improve the efficirncy of the solar cell devices.
The synthetic temperature 180¢J and rection time 48hrs are the best condition in nano spherical powder experiment.The synthetic temperature 180¢J and reaction time 42hrsare the best condition in nano rods experiment.The synthetic temperature 210¢J and reation time 24hrs,we synthesize CuGaSe2.And in the kinetic mechanism of nano powder,we think that the second phase is the important factor that influence the growth of nano poweder,and also influence the size of powder.
