Shenzhen Wanyelong Industry Co., Ltd. (formerly known as Wan Ye Long Glass Products Co. Ltd.) was established in December, 1993. Our company focuses on glass processing and trade. After years of efforts, our company has developed rapidly and has gained confidence and support from a great number of customers by good reputation and effective services. Our company has established and maintained efficient operation of a bulk sale network, and obtained a big market share. Today, our company has developed into an integrated operation combining both glass processing and glass trade.Also our branch company-Guangdong Shenzhen Wanyelong Solar Technology Co.,LTD is a high technology company which professionally produce A-Si thin film modules,develop and design solar dynamoelectric system.Wanyelong Solar technology prophase invested 280 million to build a producing base over 50,000m2,had advanced producing and testing equipment and professional staff. Now,company has producing ability over 5 MW,the transitional rate of photoelectricity could be 6%. In the meantime,the develop Dept. commit themselves to the solar resource,supply production with environment,fashion, applied and low price,to make the new solar resource to humen-life.A-Si thin film advantage and distinguishing Amorphous silicon, or more precisely a-Si:H, based thin-film photovoltaic cell has been successfully used in a wide range of solar battery applications for several decades. Silicon is abundantly available, and is known to be stable and environmentally safe.The basic device is constructed by depositing on conductive substrate, such as a TCO coated glass, layers of a-Si:H alloy with different doping agent to form a p-i-n junction, and caped with another conductive layer to form back contact.Much development efforts have been put into improving the device in the last 30 years. Recent innovations have made amorphous silicon one of the most promising and mature commercial PV technology for low cost power generation.
