What happened to Konarka?
Konarka Technologies, Inc. In late May 2012, the company filed for Chapter 7 bankruptcy protection and laid off its approximately 80-member staff. The company’s operations have ceased and a trustee is tasked with liquidating the company’s assets for the benefit of creditors.
What is single layer organic solar cell?
Single layer organic photovoltaic cells are the simplest form. 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.
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 organic solar cell work?
A typical organic solar cell consists of two semiconducting layers made of plastic polymers and other flexible materials. The cell generates electricity by absorbing particles of light, or photons. This continuous movement of electrons from hole to hole produces an electric current.
Why is Konarka no longer in operation?
It was its tech, according to a recent report from Lux Research. Konarka Technologies, the organic thin-film solar company that recently filed for bankruptcy, was the victim of its own technology, not market conditions, according to a recent analyst report from Lux Research.
Why did Konarka shut down?
After raising at least $185 million in private capital for its solar power technology, Konarka Technologies Inc. is selling off its assets as part of a Chapter 7 bankruptcy protection filing.
Which electrodes are used in solar cell?
4.4. Device performance. The organic solar cell employs two electrodes, continuous transparent conducting oxide electrode and high work function opaque electrode. The transparent electrode allows the light to pass through and harvest the photocurrent in active layer.
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.
How long do organic solar cells last?
OPV is a rapidly emerging PV technology with improving cell efficiency (currently 18.2% certified), encouraging performance lifetime (>10 years unencapsulated), and demonstrated potential for roll-to-roll manufacturing using solution processing.
When was the first solar cell made?
1883
Take a light step back to 1883 when New York inventor Charles Fritts created the first solar cell by coating selenium with a thin layer of gold.
Where did Konarka Technologies get its name from?
The company was named after Konark Sun Temple in India. As of 2006, Konarka had received $60 million in funding from venture capital firms including 3i, Draper Fisher Jurvetson, New Enterprise Associates, Good Energies and Chevron Technology Ventures.
Who is the founder of the Konark Sun Temple?
Konark Sun Temple (Konark Surya Mandir) is a 13th-century CE (year 1250) Sun temple at Konark about 35 kilometres (22 mi) northeast from Puri on the coastline of Odisha, India. The temple is attributed to king Narasimhadeva I of the Eastern Ganga Dynasty about 1250 CE.
What kind of solar cells does Konarka make?
Konarka was one of several companies developing nanotechnology -based solar cells, others include Nanosolar and Nanosys .
Why was the Konark Sun temple called the Black Pagoda?
Theories range from natural damage to deliberate destruction of the temple in the course of being sacked several times by Muslim armies between the 15th and 17th centuries. This temple was called the “Black Pagoda ” in European sailor accounts as early as 1676 because it looked a great tiered tower which appeared black.
