Open Access articles MAY be cited more, because more people can read the entire article.  

But be careful because many "open access" journals are low quality and will publish anything in order to get your money.  Such journals are NOT likely to be cited often.

Lack of sufficient time and high search costs drives most researchers to citing from open access journals.

However, the researcher will face difficulty in obtaining valuable information that is directly related to the goal of the research or study

“Open access journals” have several benefits such as free access to research papers, less costs for research in both public funded institutions and private concerns, and improved access to information. Probably, a major advantage to the authors is higher citation rates.

Many OA journals are made free utilizing the subsidy they get through grants from funding agencies. In such cases, neither the authors nor the readers pay any money for publishing and accessing the papers. Some open access journals do so by accepting page charges or charges per article from authors. For example, PLOS (Public Library of Science) journals demand specified fees for an article. A third method is to publish the articles in a traditional subscription based journal like Nature, and after a certain period (six months or so), make their paper freely available on the Internet. If you have decided to bear the page charges, before sending the money, make sure that the OA journal is trust worthy with good impact factor.
