Variety show photovoltaic conversion efficiency of 10.28% of the silicon thin film solar cells

Jiangsu Arts photovoltaic (ZONEPV) in the "PV EXPO 2010 Third International Solar Exhibition", showing openings of 10.28% module conversion efficiency of amorphous silicon thin film solar panels. When the silicon thin film solar cell of exhibitors dropped when the company has demonstrated high efficiency products.

Variety is the PV panel display and micro-crystalline silicon from amorphous silicon thin-film solar cells in series. Size 1109.6mm x 1309.6mm. Stable openings of the module conversion efficiency of 10.28%, opening voltage 183.025V, short-circuit current of 1.1106A, form factor (FF) is 0.6883. Maximum output power is 139.907W, panel conversion efficiency of 9.6%. The conversion efficiency as a tandem thin-film silicon solar cells is higher. However, these are at a temperature of 21.3 °C measured values.

Variety is a one-stop production of amorphous silicon photovoltaic thin film solar cell and module manufacturers. Shanghai across the Yangtze River with the sea about 100km north of a production base in Nantong. The company is currently building the size of annual production capacity of 80MW manufacturing facility has been completed 30MW scale.

In June 2009, at the "PV JAPAN 2009" on the various manufacturers competing to display a silicon thin film solar cells. But this is completely different, the types of solar cells exhibited drastically reduced. In particular, many manufacturers are not manufacturing equipment exhibition.

Nokia mobile phone revolution in the development of energy kinetic energy battery

According to foreign media reports, Nokia's recent application for a patent, it will develop a way to use the phone generated by small kinetic energy into electrical energy technology, which allows mobile phone batteries, like mechanical watches as the self-charging.

This technique is the use of a mechanical watch and similar devices, the quality of the phone's built a heavy rail, in the daily use of mobile phones, the guide will be with the phone's movement speed or rotation, driven by the internal battery power devices generate electricity, the small power aggregation into large electric power to supplement the cell phone battery power.

If this technology can be developed and put into use, it will greatly improve the phone's standby time. Currently, the battery technology development functions of the phone has become a bottleneck.

Report that a serious surplus production capacity of automotive batteries

International management consulting firm Roland Berger yesterday released a new market research report shows that battery costs will decline significantly in 10 years, thus promoting the automotive battery industry. However, the report also warned that plans to invest in accordance with the current enterprise computing, automotive battery industry in 2014-2017 will lead to serious overcapacity, which will result in the next 5-7 years, only 6-8 global battery manufacturers to survive.
