How to connect solar cells to simpowersystems blocks???

I am implementing a PV system using MPPT and Dc-Dc converter for my degree project. I want to use the solar cell blocks from simelectronics and connect them to a dc-dc converter made from simpowersystems. I know that the 2 subsystems are not compatible and I have used sensors to connect them together. The problem is that the results i'm getting are not good.

When i use a voltage sensor, the current values are unrealistic. The system is acting as an ideal voltage source. And, when i use a current sensor, it is voltage values which are unrealistic. Many websites have suggested to do that way but it is not working properly.

I have attached my file. Plz help.
