Although the technology of solar cells. Has been developed continuously and reliably. Using the semiconductor crystals of silicon (Crystalline Silicon) with high purity and efficiency in the change of the sun.12-17% (Eppo.go.th, 2015) but the price of silicon crystal solar cell Can't be reduced again much due to Crystalline Silicon is the important component of the industry, electronic so valuable. (Value Added) higher. The process in the production of solar cells from Crystalline Silicon to bring the saw into sheets (Wafer) thin can cause loss. In the manner of sawdust to at least half. However, many manufacturers of solar cells Try to develop to reduce production, etc. by pulling a film (Ribbon) and the use of Silicon not are crystal is Amorphous Silicon. In the thin film coated on glass plate or sheet but Amorphous Silicon is less effective than and will deteriorate faster than a lifetime Crystalline Silicon so. They are trying to develop other compounds, such as Copper Indium Dieseline (CIS) and Cadmium Telluride (CdTe).Steel bent curved by the way, then this can help reduce production costs down as much as possible which is expected to have a higher efficiency and a longer lifespan than Amorphous Silicon. It is expected to bring to market solar cells in 5-10 years. Ahead with the price, which is expected to be cheaper than a Crystalline Silicon about half. The development of solar cells is the developed to a power conversion device cheaper more than the past.
