Solar Power Innovations

light-bulb-solarRain means clouds and clouds mean less sunlight. That can mean bad news for most solar cells, but a new design can actually make use of rain drops that fall on its surface, allowing it to generate electricity even on a rainy day. Now, a group of researchers at the Ocean University of China in Quingdao are looking at combining super-thin graphene with solar panels to produce incredible results.

They believe that the world can easily extract energy using solar panels even when it’s raining or during nighttime with graphene solar panels. This capability is achieved through a chemical reaction that happens when water drops are introduced to graphene. Not just any old water drops will do, however. It’s rain water that the researchers are after, because it consists of various other chemicals, including salts—which can split up into positive and negative ions. The graphene sheets in place of ordinary panels separate the positively and negatively charged ions and in turn, generate electricity.

Have you ever been traveling or taking a hike to find out your phone is about to die? Now you can stay prepared no matter what the situation. When fully charged the Green Lighting Portable Phone Solar Charger, the 4.5 volt, 0.4 watt solar panel will absorb energy from sunlight to recharge the internal 2000mAh Lithium-Ion battery. The convenient suction cup allows you to stick your charger to a window so even while you’re indoors you can recharge your battery. Travel around knowing you won’t have to worry about your phone dying.
