Thin-Film Solar Panels
Deposition of one or more layers of photovoltaic material on a thin podolzhku is the main method of production of thin-film solar cells and modules. There are various subtypes tokoplenochnyh solar modules, which differ in substrate material and the layers used:
- Amorphous silicon (a-Si)
- Cadmium telluride (CdTe)
- Copper, indium, gallium and selenide (CIS / CIGS)
- Organic elements (OPC)
Depending on the technology, the efficiency of thin-film modules is in the range 7-13%. It is expected that the efficiency of these modules will increase in the future, up to about 10-16%.
The market of solar panels on thin films grown by 60% between 2002 and 2007. In 2011, thin-film technology has been used for the production of 5% of photovoltaic modules designed for the private sector.
- The relatively low cost of production, compared with the crystal module. As a consequence – lower cost.
- Due to the homogeneity of thin-film panels – they look aesthetically pleasing.
- There is a flexible thin-film modules
- Less heat loss in consequence of indirect lighting
- It requires a large area for installation
- Lower occupancy and lower efficiency means longer need to purchase reference designs, cables, etc., which increases the cost of the final grid
- Less lifetime. Less warranty.
