摘要：

CCD photometric observations of the eclipsing binary PS Persei (PS Per) were obtained on two consecutive days in 2009. The 2003 version of the Wilson-Devinney code was used to analyze the first complete light curves in the V and R bands. It is found that PS Per is a short-period Algol-type binary with the less massive component completely filling its inner critical Roche lobe. The mass ratio of q = 0.518 and the orbital inclination of i = 89.86 degrees are obtained. In addition, based on all available times of primary light minima, including two new ones, the orbital period has been improved.
