摘要:
After a liquid-phase epitaxial growth step by an n-type GaAs saturated solution (21) is terminated, a substrate (1) is temporarily dipped in an undoped GaAs saturated or supersaturated solution (22), and thereafter liquid-phase epitaxial growth is performed by a p-type Al x Ga 1-x As saturated solution (23). Thus, the n-type GaAs saturated solution (21) is prevented from being mixed into the p-type Al x Ga 1-x As saturated solution (23) to contaminate the same, whereby a solar battery of high quality can be obtained even if the number of times of crystallization is increased.
