The Design of Multi-function Solar Charger for Mobile Phones

ABSTRACT: A new multi-function solar charger for mobile phones was designed and tested based on problems embedded into similar products available in the market. To improve its performance, an adjustable flat reflector and 4 Ni-H rechargeable cells were equipped together with a multi-crystal silicon solar cell as a whole of the device. A field test showed that the output of solar cell could be increased by 41.3% due to the use of reflector. This device can be used at any climatic condition due to use of rechargeable cells.
KEY WORDS: Solar cell; Charger; Flat reflector; Ni-H rechargeable cell

我的英文肯定是有问题的，哪位帮我改下或重写下，不胜感激啊!谢谢！

改了順点!

ABSTRACT: A new multi-functional solar charger for mobile phones was designed and tested based on problems found on some similar products available in the market. To improve its performance, an adjustable flat reflector and 4 Ni-H rechargeable cells were equipped together with a multi-crystal silicon solar cell into an integrated device. A field test showed that the output of solar cell could be increased by 41.3% due to the use of the additional reflector. This device can be used anytime, anywhere and most importantly under any climatic condition as a result of the use of the rechargeable cells.
