#390 Solar cells - efficiency

 Solar cells come in the broad range of material-device structure combinations. From elemental semiconductor  (silicon) to compound semiconductor based, from inorganic to organic semiconductors, from thin-film amorphous to single-crystal cells, from flexible to rigid, from low-cost to costly, ect. etc., performance of various classes of solar cells varies widly.

 

Parameter commonly used to describe performance of the solar cell  is its efficiency defined as a ratio of maximum power generated by the cell and the input power of the solar energy.  Efficiency of the solar cell is a function of material from which it is constructed and complexity of its structure, and thus, complexity of the processing steps employed in its manufacture. It can be as low as few % for the low-cost cells to close to 50% for the complex, multilayer cells. A universally valid rule is that the efficiency of solar cell is proportional to its cost which encompasses cost of the material used and cost of the manufacturing process.
