Sure there are small ones. Calculators use postage stamp sizes.
You want really small use a yellow LED.

As Keith said, LEDs (non-phosphor color converted like white) work as micro solar cells, generally most sensitive to their emission color.
Traditional solar cells... I easily found 17 mm diameter and 22 x 7 mm cells:

I have never had the need to look for solar cells... never expected them on DigiKey, either. Good to know. Thanks, Jim!

Years ago did a design of a level sensor that used a bubble level tube with a light source on one side and two solderable photo sensors (custom) on the other. Accurate to a couple arc-seconds. Part of a construction laser leveling system.
Thought I would check real quick with the type of photosensor companies that make these things today. Found this. Smallest one is 1.9 by 4.1mm, and designed for solar cell use.

Wow.
Dang small!
Pretty cool though as some very low average consumption circuits could probably use those for all their energy requirements. Way more energy than vibration or thermal-differences would typically provide.
