Photovoltaic Cells Specifications

Help with Photovoltaic Cells specifications:

General Specifications

	Material
	Your choices are...
	Amorphous Silicon		Amorphous silicon, sometimes referred to as a-Si, is a non-crystalline allotropic form of silicon. Photovoltaic cells are made from amorphous silicon.
	Monocrystalline Silicon		Mono-crystalline silicon PV cells are designed with single crystal wafers.  Has the highest efficiency of all silicon cells.
	Polycrystalline Silicon		Polycrystalline or multicrystalline silicon PV cells are designed with many crystal wafers. They are generally less efficient than mono-crystalline silicon wafers.
	Gallium Arsenide		Gallium arsenide cells are a multifunction cell that are more efficient than silicon but have a high cost and toxicity.
	Organic / Polymer		Organic/polymer PV cells used organic polymers or small organic molecules that are affected by sunlight.
	Ribbon Silicon		Also known as a ribbon wafer, this cell is designed with thin strips of silicon that are melted together.
	Thin Film		Thin-film PV cells are made of thin layers of semiconductor material.  Thin-film cells generally are less efficient than silicon and gallium arsenide.
	Other		Other, specialized type of PV cell material.

Performance Specifications

	Power		The output power of the solar cell.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Efficiency		The efficiency of the solar cell.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Open Circuit Voltage		The open circuit voltage is maximum voltage of the cell when the device is under infinite load, or in an open-circuit situation.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Short Circuit Current		The short circuit current is the maximum current when the cell is under zero load.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Peak Voltage		The maximum voltage produced by the panel or cell.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Peak Current		The maximum current produced by the panel or cell.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Standard/Certifications

	Standard/Certifications
	Your choices are...
	ASME		The power generator is ASME certified.
	CSA		Products that bear a CSA Mark have been tested by the Canadian Standards Association (CSA) and meet applicable standards for safety and/or performance. These standards are written and administered by organizations such as the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and CSA International.    CSA Marks may appear alone or with indicators. CSA Marks that appear alone are used with products certified primarily for the Canadian market, to the applicable Canadian standards. CSA Marks that appear with the indicators “C” and “US” or “NRTL/C” is used with products certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards.
	IEC		The International Electrotechnical Commission (IEC) is a global, non-profit organization that develops and maintains voluntary quality, safety, and performance standards for electrical materials, products, and systems The IEC also publishes standards for the electronics and telecommunications industries. The IEC’s membership consists of the electrotechnical standards organizations from each of its 51 member nations. The American National Standards Institute (ANSI) represents the United States.
	IEEE		The power generator is IEEE certified.
	NFPA		The power generator is NFPA (National Fire Protection Association) certified.
	RoHS Compliant		Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ether. RoHS became effective on July 1, 2006.
	UL		Underwriters Laboratories (UL) is a non-profit organization that tests components, systems, and materials according to its published standards for safety. Products that receive UL approval bear a UL Mark.
	WEEE Compliant		“The Waste Electrical and Electronics Equipment Regulations (WEEE Regulations) is a European Parliament Directive with the aim of encouraging reuse, recycling and recovery of electrical and electronic equipment, and to improve the environmental impact and performance of these equipments."  This directive sets the requirements and criteria for the collection, treatment, recycling and recovery of these equipments. It makes producers responsible for financing these activities, and retailers and distributors must provide means for consumers to return used or obsolete equipments without charge.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
