While this definition is also adequate for several other photovoltaic technologies, including thin film solar cells constructed from multi-junction solar cells due to their wider absorption bandwidth of 300 1800 nm.
32.
Concerns with the price and availability of indium in CIGS and tellurium in CdTe, as well as toxicity of cadmium have been a large motivator to search for alternative thin film solar cell materials.
33.
Macro-architecture of the solar cells could result in different surface areas being placed in any fixed volume-particularly for thin film solar cells and flexible solar cells which may allow for highly convoluted folded structures.
34.
Recent research has experimented with lead selenide ( PbSe ) semiconductor, as well as with cadmium telluride photovoltaics ( CdTe ), which has already been well established in the production of second-generation thin film solar cells.
35.
Each thin film solar cell would have a different band gap which means that if part of the solar spectrum was not absorbed by the first cell then the one just below would be able to absorb part of the spectrum.
36.
There are four main categories of photovoltaic cells : conventional mono and multi crystalline silicon ( c-Si ) cells, thin film solar cells ( a-Si, CIGS and CdTe ), and multi-junction ( MJ ) solar cells.
37.
Solar cells made from c-Si are single-junction cells and are generally more efficient than their rival technologies, which are the second-generation thin film solar cells, the most important being CIGS, and amorphous silicon ( a-Si ).
38.
Leveraging on the common technologies with optical disc manufacturing technology, the Group developed the solar business in 2008 to sell production system for thin film solar cell and engaged in solar cell manufacturing and trading business and also in R & D in OLED panel manufacturing technology.
39.
While the commercial success of flat-panel display opens an era of large area electronics, other emerging applications, such as rollable display, printable thin film solar cell and electronic skin, demonstrate further desirable attributes for macroelectronic systems, including flexibility, portability and low-cost.
40.
For instance, a comparison between primarily quadratical solar cells like typical crystalline silicon solar cells and narrow but long solar cells like typical thin film solar cells can lead to wrong assumptions caused by the different kinds of current paths and therefore the influence of, for instance, a distributed series resistance contribution to " r"
