Justifying sub-optimal research quality by lack of supervision
You should be very, very careful about seeming to criticize your own department or supervisor. It might be unfair that you received sub-optimal results, but if you try to blame somebody else for your results, search committee members are much more likely to just think you are a complainer or a malcontent. 

The best advice at this early stage in your career: either find a way to work together better with your advisor, or switch advisors.
