long-term stability of polymer solar cells is improving - polycarbonate sheet manufacturers
The polymer solar cell in the general conductive polymer was A as early as 1976. Heeger and A. MacDiarmid.
The first step is to doping these polymers to produce insulators, conductors, and semiconductorsconductors.
The idea of using these materials in solar cell technology was presented in 1992.
Advantages of polymer solar cells or organic photovoltaic cells (OPVs)
It is based on the extraordinary properties of the polymer.
These materials are lightweight, flexible, cheap and easy to produce.
All of these properties make these materials ideal for industry and families
Applications based on solar cells can be integrated into fabrics and buildingsintegrated PVs.
The production and operation of polymer solar cells is a "greener" process than conventional silicon batteries.
Polymer is also used for solar energy-
Control light products (
Protect a building or as a means of transport from excessive heat and harmful sun light, while allowing a high degree of transparency over visible light.
Thanks to advances in this area, Polymer solar glass is finally available at low cost.
The status quo of leading companies in the field of organic photovoltaic is Konarka and Solarmer Energy.
Konarka is mainly an OPV manufacturer, providing a wide range of solar cell applications for other companies.
The company set six world records.
OPV efficiency was 4% in May 2009.
On the other hand, Solarmer Energy set three consecutive world records in 2009. 8 %, 7. 6 % and 7.
The National Renewable Energy Laboratory has certified 9% projects.
They set eight world records in May 2010. 13 %.
Konarka managed to achieve 8 recently.
3% efficiency, which was announced and confirmed by the National Renewable Energy Laboratory in December 2010.
The company has installed polymer solar cells on the outside of large buildings in Florida and bus stops in San Francisco.
They also plan to use new technologies in the production of consumer goods such as luggage and umbrellas.
Difficulties and problems to be overcome in OPV technology is still in its infancy.
Although it already has or may have advantages in the future, the efficiency is still very low compared to traditional PVs such as silicon batteries, with an average efficiency of 14-18%.
Some can even achieve 20% efficiency.
Another drawback of polymer solar cells is the short life span, which increases the cost of use and production.
The following figure shows the structure of polymer solar cells.
In order to solve the problem of low efficiency and short life span of OPVs at present, researchers are constantly testing new materials, structures and combinations.
Their goal is to achieve long-term
The long-term stability of polymer solar cells will make it a commercially viable solution for battery technology.
Polymer solar cell technology may become very competitive in the next few years.
The next goal for OPV manufacturers is to achieve 10% efficiency by the end of 2011.
If polymer solar cells are to dominate the future solar cell market, it is absolutely necessary to improve efficiency.
