Light can be stored or not

Before going for an answer first of all we should know the properties of light.

the properties which light possesses are
*Reflects: bounces off and goes along a different direction. This applies to opaque objects like walls or mirrors.

*Passes through: Goes right through the object, such as glass.

*Gets absorbed: and become released as heat energy.

YES. Light can be stored

Convert the light into something that can be stored and then convert that back into light when need it.
EXAMPLE :PHOTO-VOLTAIC CELL

It is a semiconductor diode that has the capacity to convert visible light into direct current
But then another question arises i.e 

Can we store light as light itself?
The answer is YES.
 
Suppose if we had a box that was made of material that is 100% reflective inside.
 
In reality, even extremely reflective things are at best ~99% reflective. That means each time the light in the box hits the wall, it is 99% of its former intensity. 

 The rest is lost through absorption.
So practically we cannot store light as light itself

IF WE DESIGN A MATERIAL WHICH IS 100% REFLECTIVE WE WILL BECOME A Millionaire
