I am wondering if there is a heat absorbing material that can absorb heat material at high rate , especially in summer and that heat can be converted to electricity for storage in my battery bank to light my LED lamps.

There are plenty of heat absorbing materials out there. But to your specific question, you can't convert heat directly to electricity. You need to use a Carnot Heat Engine type mechanism to do this.

Well a peltier device will do it, but at very bad efficiency (like 4%).
