How do organic solar cells work?
Organic solar cells are based on the photosynthesis process in plants. The absorption of light in organic cells is done by the ‘dye’ which substitutes for the silicon in conventional cells. This light causes the dye molecules to excite and release electrons that are converted to electrical energy.
What is solar Organic?
An organic solar cell uses carbon-based materials and organic electronics instead of silicon as a semiconductor to produce electricity from the sun. Organic cells are also sometimes referred to as “plastic solar cells” or “polymer solar cells”.
How efficient are organic solar cells?
“A typical silicon-based solar cell can reach efficiencies as high as 20 to 25%, while organic solar cells can reach efficiencies of around 19% under laboratory conditions, and real-world efficiencies of about 10 to 12%.”
Why are organic solar cells better?
Advantages of Organic Solar Cell Organic solar cells have the ability to utilise larger areas than its inorganic counterparts. Containing flexible solar modules, organic cells can be fabricated using roll-to-roll production, a process that is less costly than the conventional manufacturing way.
Why are organic photovoltaics better?
Benefits. The benefits promised by OPV solar cells include: Low-cost manufacturing: Soluble organic molecules enable roll-to-roll processing techniques and allow for low-cost manufacturing. Abundant materials: The wide abundance of building-block materials may reduce supply and price constraints.
What are the advantages and disadvantages of organic solar cells?
➨The efficiency of organic solar cells is less (about 5%) compare to silicon solar cells (about 15%). They are stable in the dark but degrade in the light conditions. Moreover as electricity can not flow very easily in organic solar cells (OSCs), its efficiency is limited.
