The CCD photometric observations of the eclipsing binary PS Persei ( PS Per ) were obtained on two consecutive days in 2009 .
The 2003 version Wilson-Devinney code was used to analyze the first complete light curves in V and R bands .
It is found that PS Per is a short-period Algol-type binary with the less massive component accurately filling its inner critical Roche lobe .
The mass ratio of q = 0.518 and the orbital inclination of i = 89. ^ { \circ } 86 are obtained .
On the other hand , based on all available times of primary light minimum including two new ones , the orbital period has been improved .
