Hi guys,
can anybody give me some info regarding the pic? well, the one in the right is an IR LED and there is also a ceramic capacitor but can anyone give me some info regarding the IR Receiver in the left with a black patch on its rectangular body?
thanks,
Surya :)

Also possible: this is a homebrew IrDa device or only receiver and trnsmitter.(another side of PCB invisible)

The capacitor seems to be for power supply decoupling. But I am not sure since I don't know where it is connected. Do you have the circuit diagram with you?

Chances are that yes it is decoupling. When a capacitor is placed that close to the pins.
I'm looking at the datasheet for a PNA4602M (an infrared detector module) and that has....
if you were counting the pins left to right signal out, Gnd and Vcc. This is not the same part but the placement of the capacitor would suggest it is possibly close in function and pin out. The sharp datasheet says it may need a capacitor depending on the operating enviroment
