Hetereojunction solar cells combine two different technologies into one cell.

A leading manufacturer of space solar cells and panels. The maximum theoretical efficiency that a single bandgap solar cell can achieve with non concentrated sunlight is about 33 5 primarily because of the broad distribution of solar emitted photons. This means that theoretically multi junction solar cells are capable of converting more sunlight that hits them to electricity when compared to single junction cells. The photovoltaic effect is a complicated chemical and mechanical process but can be summarized in three main steps.

Multi junction compound semiconductor solar cells from the iii v family are capable of gaudy efficiency numbers. It is a form of photoelectric cell defined as a device whose electrical characteristics such as current voltage or resistance vary when exposed to light. Researchers at nrel just announced a 31 1 percent conversion efficiency for a. For the first time an efficiency of 25 9 percent has been achieved with a multi junction solar cell grown directly on a silicon substrate.

High efficiency multijunction devices use multiple bandgaps or junctions that are tuned to absorb a specific region of the solar spectrum to create solar cells having record efficiencies over 45. Used together these technologies allow more energy to be harvested compared to using either technology alone. Each material s p n junction will produce electric current in response to different wavelengths of light. A crystalline silicon cell sandwiched between two layers of amorphous thin film silicon.

A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon. Multi junction solar cells are capable of absorbing different wavelengths of incoming sunlight by using different layers making them more efficient at converting sunlight into electricity than single junction cells. Multi junction mj solar cells are solar cells with multiple p n junctions made of different semiconductor materials. Includes product data sheets and online store.
