A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI(G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper indium gallium selenide solid solution on glass or plastic backing, along with electrodes on the front and back to collect current.
Flexible solar cell research is a research-level technology, an example of which was created at the Massachusetts Institute of Technology in which solar cells are manufactured by depositing photovoltaic material on flexible substrates, such as ordinary paper, using chemical vapor deposition technology.
The favorable values in the table below justify the choice of materials typically used for multi-junction solar cells: InGaP for the top sub-cell (E g = 1.8–1.9 eV), InGaAs for the middle sub-cell (E g = 1.4 eV), and Germanium for the bottom sub-cell (E g = 0.67 eV). The use of Ge is mainly due to its lattice constant, robustness, low cost ...
Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...
Three-layer GaAs cells achieved 41.6% efficiency for experimental examples. [9] In September 2013, a four layer cell reached 44.7 percent efficiency. [10] Numerical analysis shows that the "perfect" single-layer solar cell should have a bandgap of 1.13 eV, almost exactly that of silicon.
A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current ...
In the broader category of thin film solar cells, as of 2007 the company was the second-largest U.S. manufacturer, after First Solar. [6] The solar cells are made of 11 triple junction amorphous silicon solar cells connected in series and have 11–13% in conversion efficiency. [7] The laminate encapsulation material was durable ETFE, high ...
