Solar Energy

Imagine a world where sunlight can be captured to produce electricity anywhere, on any surface. The makers of thin-film flexible solar cells imagine that world too. But a big problem has been the amount of silicon needed to harvest a little sunshine.Now, researchers at Caltech say they’ve designed a device that gets comparable solar absorption while using just one percent of the silicon per unit area that current solar cells need. The work was published in the journal Nature Materials.

In recent years, the solar energy for the benefit of mankind's technology industry has become more and more developed.Human has a long history to use the solar energy. “China as early as two thousand years ago, during the Warring States period, know the use of four steel mirror to focus sunlight ignition; use of solar energy to dry agricultural products.”The development of modern, solar energy has become increasingly widespread use, which includes the use of solar energy solar thermal, solar photovoltaic.What’s more solar energy was used by photochemical and so on.People use the solar energy in two ways: the photothermal conversion and the photoelectric conversion.

At present, many scientists hold optimistic attitude on the prospect of the solar energy .There are three reasons:（1）General: the sun shines on the earth, whether land or sea, regardless of the mountains or islands, are found everywhere, direct the development and utilization, and exploitation and transportation needless. (2) Sound: the development and utilization of solar energy will not pollute the environment, it is one of the most clean energy。For today's increasingly serious environmental pollution, it is extremely valuable. (3) The great amount: “the solar radiation which reach the earth's surface each year about 130 trillion t standard coal.Therefore the solar energy has the largest amount among nature sources.” (4) constancy : according to estimation at present about the rate of nuclear energy produced the sun, the amount of hydrogen storage is sufficient to maintain human for the tens of billions of years, and the earth life is only about billions of years. In this sense, the solar energy can be inexhaustible.

On the other hand, we can’t ignore the disadvantages of solar energy. First,solar has dispersion.Although there is the large amount of scatter solar radiation reaching the earth's surface, energy density is low.Second solar has instability. due to diurnal, season, geographical latitude,altitude restrictions and other natural conditions, and clear, Yin, cloud, rain and other random factors, solar irradiance reaching a certain surface is continuous and very unstable, which increased the difficulty for the solar energy large-scale applications.Third,solar has the low efficiency and high cost. “The current development level of solar energy utilization, is feasible in theory and technology is mature too. But some of the solar energy utilization device, because of the limitation both of efficiency and cost, in general, can't compete with conventional energy . In the future a considerable period of time, the further development of solar energy utilization, mainly faces much difficulty for economic constraints.”

In a word,if we can solve these difficult problems,human will take better use of the solar energy.

篇二:《自制太阳能风扇》

自制太阳能风扇{制作太阳能作文}.

“快点按上！快点！”这时什么声音？告诉你吧，我们在做太阳能小风扇呢！

开始做了，我们先拿出所有的零件，其中有：风叶，鳄鱼夹线，方柱，黄色底板，太阳能板，四毫米螺丝，十六毫米螺丝，电机固定片，L型铁轴架。我先把铁轴架放在黄底板上，用螺丝固定住。然后把方柱放在铁轴架上，用螺丝固定住。

开始安腿了，我用螺杆拧在在黄色底板上，当它的四条腿。然后把电机固定片放在方柱的上面，用螺丝固定住。把马达放在电机固定片的中间。我想这能转起来吗？然后把小风扇按在马达上。用两个鳄鱼夹，一头夹住马达的小耳朵，另一头夹住太阳能板，这样就做完了。我拿到外面去看看转吗？果然转开了。我开心地说：“转起来了”{制作太阳能作文}.

很快科学小实验就结束了，可是我们高兴的心情依然存在。

篇三:《我的太阳能热水器》

我的太阳能热水器

星期天早晨，我做了一个太阳能热水器，主要材料用的是可乐罐。我先买一罐可乐喝了，用清水把可乐罐洗干净，再把可乐罐装满水，放到阳台上晒太阳。下午太阳快下山的时候，我去阳台一摸可乐罐，啊，好热呀！我的太阳能热水器成功了。我赶快把这件事告诉了爸爸、妈妈，他们都很高兴，夸我是个好孩子。

晚上我做了个梦，梦见所有人都用我的太阳能热水器洗澡，可以省好多好多的电。

方便的太阳能游艇广东省深圳市盐田区田心小学六（2）班袁小婷许多人因工作太卖力而感到疲乏，多余的时间想轻松一下。怎么轻松法呢？有些人会呆在家

里睡大觉，也有些人会约老朋友在船上谈自己的生活事情，可是在船上容易摇摇摆摆，怎么

办呢？哦！原来我们新建的太阳能游艇已经上场了。这是一种特殊的游艇，不会摇摆。是有

顶的。第一艘以太阳能和风能为动力的游艇最近在悉尼下水，它能运载一百名乘客。这艘游

艇由太阳能电池板吸收阳光供能。太阳能是很厉害的，一些物体如果吸收了太阳，这些物体

就回启动起来。游艇也一样，也是靠太阳来奔驰于水面。这艘游艇分为四人座.六人座和四十
