silicon solar cell.
In this paper, we will discuss what a solar cell is and its history in the first part. To study DSSC, 1st generation solar cell which is silicon crystal and 2nd generation which is multijunction solar cell is introduced. Inparticular, prosand consand principle of DSSC we have studied dare discussed, and we predict absolution of low efficiency with size effect and multijunct i

silicon form familiar materials such as silicones, examples being silly putty and waterproof plumbing sealant. Oxygen is also commonly present in polymer backbones, such as those of polyethylene glycol, polysaccharides (in glycosidic bonds), and DNA (in phosphodiester bonds).
Polymer properties are broadly divided into several classes based on the scale at which the property is defined as well a
Sodium detaches itself,
leaving only carboxyl ions.
Being negatively charged,
these ions repel one another.
The polymer unwinds and absorbs water,
which is attracted by the sodium atoms.
