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.
Why are organic solar cells less efficient?
As there is a stronger attraction between the electron and hole in carbon-based materials than in silicon, organic solar cells are more prone to recombination, which in turn affects their efficiency.
What is the difference between organic and inorganic solar cells?
While inorganic photovoltaic cells utilize crystalline elements as a light absorber, organic photovoltaic cells utilize molecules or polymers to convert sunlight into electricity.
What are the types of organic solar cells?
Based on their method of production, organic polymeric-based solar cells can be further classified into three types: organic bulk heterojunction thin-film solar cells, organic tandem solar cells, organic DSSCs.
Who invented organic solar cell?
1953 – Gerald Pearson begins research into lithium-silicon photovoltaic cells. 1954 – On April 25, 1954, Bell Labs announces the invention of the first practical silicon solar cell. Shortly afterwards, they are shown at the National Academy of Science Meeting. These cells have about 6% efficiency.
How does solar energy work simple explanation?
When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
