ORGANIC SOLAR CELLS

About:

• Organic solar cells are made of thin layers of organic materials with thickness in the 100-nanometre range.
  
  
• They were first introduced by the research group of Dr. Ching Tang at Kodak Research Laboratories in 1986.
  
  

Working:

• Organic solar cells basically comprise the following layers: first electrode, electron transport layer, photoactive layer, hole transport layer, and second electrode.
  
  
• In general, a solar cell absorbs light, separates the created electrons and holes from each other and delivers electrical power at the contacts.
  
  

Benefits:

• Compared to silicon-based devices, polymer solar cells are lightweight, potentially disposable and inexpensive to fabricate, flexible, customizable on the molecular level and potentially have less adverse environmental impact.
