Build Solar Cell
In this article we will learn how to build solar panel photo that. As Grätzel cell after scientist named who developed this technology photo cell imitates nature in ways that plants enjoy and absorb UV light from the sun. Radiant energy is transmitted similar to photosynthesis into electrical energy by chemical processes in the solar cell.
When light transparent electrode meets, dye in the cell excited and electrons are discharged. Photochemical solar cells are able to produce even cheaper than photovoltaic, because titanium dioxide used in this process together products such as paints and tooth paste is readily available. Titanium dioxide can products such as whitening toothpaste and titanium white paint are found together.
Build Solar Cell
To make this type of solar cell, grind titanium dioxide into small particles using mortar and pestle. Next, coat powdered suspension onto glass plate. You can easily spread powder by using small glass rod.
Be sure to get even coverage of titanium dioxide to boost reaction rate. Reduce resistivity of titanium dioxide by sintering it. most conventional method of heating plate to approximately 450 degrees Celsius 842 Fahrenheit is to sinter it over tip of Bunsen flame.
steady exposure of fifteen minutes is enough to allow titanium dioxide particles to adhere into film. To sensitize solar cell, first crush up handful of berries. Use mortar and pestle to produce deep red or purple fluid.
You can use blackberries, raspberries, strawberries, or even pomegranate seeds to make dye. Take electrode which has been coated in titanium dioxide film and spread berry fluid onto it. Make sure dye is evenly spread.
