Photogalvanic Cells
Photogalvanic Cells are resemble regular galvanic cells. One of the half-cells is assembled using a photoelectrode, and this electrode needs to be irradiated with light in order to generate electricity.
Assembly of a titanium dioxide photoelectrode
In this video, the assembly of a photoelectrode from FTO glass and titanium dioxide is shown step by step - from the required materials to the application of the titanium dioxide layer to sintering on a hotplate.
Assembly of a photogalvanic 2-Pot-Cell
The assembly of a photogalvanic Two-Pot-cell, which is similar to that of a daniell cell, is show in this video. At the end of the video, it is also shown, that the assembly is photosensitive, by irradiating the photoelectrode with light from a torch.
Assembly of a photogalvanic 1-Pot-Cell
In this video the assembly and operation of a photogalvanic cell on the basis of titanium dioxide is shown in a 1-pot-configuration.
Assembly of a photogalvanic compact cell
In this video the assembly and operation of a photogalvanic compact cell is shown.
Directions on photosesibilisation
The video shows, how a photoelectrode based on titanium dioxide can be sensitized using substances derived from natural products.
Operation of a motor using a photogalvanic compact cell
The video shows very shortly, how a photogalvanic compact cell powers a small motor when irradiated with uv light.
Powering a Motor with a photogalvanic One-Pot-Cell
The video shows how a motor is powered using a photogalvanic one-pot-cell while the cell is irradiated with light.
With Raspberry Juice sensitized photogalvanic 1-pot-cell
In the video a photoelectrode, sensibilized using raspberry juice is compared to one that hasn't been photosensibilized. The difference between both electrodes becomes apparent when irradiating them with red light.
Photogalvanic 1-Pot-Cells with Flash Lights
In the Video a sensitized and a not sensitized photoelectrode are compared with one another when irradiated with different wavelength of light from LED flash lights.
Compact Cells irradiated with Sunlight
Several types of compact cells are shown that power a motor each when irradiated with sunlight. The duration the motor is running is dependent on the electrolyte and the make up of the cell.
