使用者可以準備帶著手機去外面作日光浴了──摩托羅拉(Motorola)宣佈取得了一項專利，該技術可透過嵌入到液晶顯示螢幕中的太陽能電池來為手機充電。儘管這並不是什麼新創意，摩托羅拉卻宣稱已解決了如何使太陽能電池獲得足夠光能量來給電池充電的問題。
如果摩托羅拉成功將此一技術投入市場，未來消費者不再需要將充電器連接到電力插座中為手機充電，因為該手機會不斷地利用太陽能充電。摩托羅拉表示，該公司採用了一種特殊液晶材料，使照射到LCD上的光能量有75%甚至更多被轉到太陽能電池上。
摩托羅拉表示，透過用膽固醇(cholesteric)和聚合物(polymer)取代向列型晶體(nematic crystal)，將不再需要過去用於LCD中來照亮顯示螢幕的金屬反射器(metallic reflector)；如果使用這種反射器，會使抵達太陽能電池的光量減少到6%以下，根本不夠對電池進行充電。
摩托羅拉在聲明中表示，儘管先前已有類似技術取得專利，但摩托羅拉的專利卻是一個更能在商業上被接受的方案。該公司表示：「一般的低成本液晶顯示技術能用以生產可接受的顯示器解決方案，卻無法提供足夠的光量到太陽能電池。」
不過摩托羅拉對這項應是在上個月通過的專利技術沒有發表其他評論；目前太陽能電池僅應用在計算機等低功率的簡易電子裝置中。 Motorola gets patent for sun-powered mobile Phone
Are cell phone users ready to take their handsets outside and soak up the sun?

Motorola has been awarded a patent for technology the company says will make it possible to recharge the battery of mobile phones through solar cells embedded within the liquid crystal display.

The idea is not new, but Motorola claims in the patent that it has solved the problem of getting enough light to the solar cells to recharge the battery.

If Motorola were to successfully go to market with such a product, then the company would effectively eliminate the need to recharge a cellular phone's battery through a separate transformer that plugs into an electrical socket. The phone would always be charged.

Motorola believes it can get 75% or more of the light entering through the front of an LCD to the solar cell by using a different type of liquid crystal. By switching from nematic crystals to cholesteric or polymer disbursed, Motorola says it can eliminate the use of a metallic reflector that's used in LCDs to illuminate the screen. The use of such reflectors reduces the amount of light that could reach a solar cell to less than 6%, which is insufficient to recharge the battery.

While technologies addressing the problem have been patented before, Motorola's invention is a "more commercially acceptable solution," the company said in the patent.

"Relatively ordinary and cost-effective liquid crystal display technologies can now be utilized successfully to provide an acceptable display and nevertheless provide an acceptable level of light to a stacked solar cell," the company said.

The patent appears to have been awarded last month. Motorola was unavailable for comment. Solar cells are used today to power very low-power electronic gadgets, such as calculators.
