To give it more surface area in order to maximize its gas diffusion function
Why Does Red Blood Cells Have Biconcave Shape?
1-provide more surface area
2-due to lack of nucleus
3-so that they could pass through small capillaries
4-distruction in spleen

Red blood cells are most important among the blood cells. Their functionis to deliver oxygen from the lungs to the whole body through the blood. They are also called as Haematids. At rest all the RBC have bioconcave share. This shape allows more and more oxygen molecules to come in contact with the cell's surface, thus making it an effective oxygen carrier.
