SOLAR CELL

 The students Lee-Ann Briggs from the Combermere School and Shanice Seale, from the Garrison Secondary School presented on alternative sources of energy and focused on using the sun to harness its energy. They showed a wide range of knowledge as Linda-Joy Forde, Head of the Science Department of the Garrison Secondary School looked on. The students presented two possible alternatives of solar cells,  in the form of a copper solar cell and a titanium solar cell. The cells both are highly cost effective in terms of their production costs and are produced mainly from locally accessed materials.

The copper solar cell functioned using  the process of electrolysis. It made use of use of coprous oxide and copper as the electrodes and simple inexpensive salt water as the electrolyte.  

The titanium solar cell was constructed using a single glass panel,  titanium oxide and raspberry juice as well as carbon emitted from a candle. They also highlighted the importance of the solar cells in relation to functioning as an alternative source for generating electricity to power simple household devices such as a radio, which can be used  during recreational activities

The projects are all developmental and will undergo further modifications over time with a view of developing to commercial production which enables the saving of foreign exchange and the recycling of some material that would normally be discarded after their initial use.
