What is organic solar cell?

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”.

What are 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 do solar photovoltaics do?

Solar PV panels are comprised of many small photovoltaic cells – photovoltaic meaning they can convert sunlight into electricity. These cells are made of semi-conductive materials, most often silicon, a material that can conduct electricity while maintaining the electrical imbalance needed to create an electric field.

Why we use organic solar cells?

The molecules used in organic solar cells are solution-processable at high throughput and are cheap, resulting in low production costs to fabricate a large volume. Combined with the flexibility of organic molecules, organic solar cells are potentially cost-effective for photovoltaic applications.

What is a benefit of using organic solar cells?

It has several promising advantages, including its lightweight, large surface area, low cost and robustness. The organic solar cell can store much larger quantities of solar energy than other solar technologies due to its high optical absorption coefficients.

How organic solar cells are made?

These cells are made by sandwiching a layer of organic electronic materials between two metallic conductors, typically a layer of indium tin oxide (ITO) with high work function and a layer of low work function metal such as Aluminum, Magnesium or Calcium.

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.

What is solar cell explain its working?

A solar cell is a sandwich of n-type silicon (blue) and p-type silicon (red). It generates electricity by using sunlight to make electrons hop across the junction between the different flavors of silicon: When sunlight shines on the cell, photons (light particles) bombard the upper surface.

What are organic photovoltaics made of?

Organic photovoltaics are made of electron donor and electron acceptor materials rather than semiconductor p-n junctions.
