Yes

Light or photons exert a very small force on matter when they collide with it. Making use of this fact (conservation of momentum) many ideas have come to forefront on how to use it to build the next generation spaceship. The benefits are obvious:
1. No need to use propellant for acceleration.
2. Can reach very high speeds (predicted 1/10 the speed of light).
3. Clean.
4. Low risk level (with regard to propellant).

There are also disadvantages to this solution as you would need a source (the sun) which would have to be close enough (within solar system). A very large mirror would be required to obtain the necessary acceleration to make a mission feasible. Take a look at these websites for more info:
