In DSSC, electrodes consisted of sintered semiconducting nanoparticles, mainly TiO2 or ZnO . @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

@albairaqqatar The excited electrons are injected into the conduction band of the TiO2 electrode.

[ABW-Pearls-7 @ABWPearls7]

The photosensitizers are excited from the ground state (S) to the excited state (S∗). @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

@albairaqqatar 1. The incident photon is absorbed by Ru complex photosensitizers adsorbed on the TiO2 surface.

[ABW-Pearls-7 @ABWPearls7]

In existing designs, this scaffolding is provided by the semiconductor material, which serves double-duty. @albairaqqatar

Today is the last day @albairaqqatar for the Twitter #help #followers .. @ABWPearls7 ..

[ABW-Pearls-7 @ABWPearls7]

Commercial applications, which were held up due to chemical stability problems . @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

The DSSC has a number of attractive features; it is simple to make using conventional roll-printing techniques @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

A dye-sensitized solar cell (DSSC, DSC or DYSC ) @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

This reaction occurs quite quickly compared to the time that it takes for the injected electron . @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

The dye strips one from iodide in electrolyte below the TiO2, oxidizing it into triiodide. @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

@albairaqqatar Several important measures are used to characterize solar cells.

[ABW-Pearls-7 @ABWPearls7]

All the Thanks for @albairaqqatar for supporting us and give us alot of instructions ..

[ABW-Pearls-7 @ABWPearls7]

Today we will put the finals details on the presentation and start with the Application of the product @albairaqqatar

[ABW-Pearls-7 @ABWPearls7]

Our Girls in the school are helping & cheering Us alots @albairaqqatar
