一个平板太阳能电池
I made a more portable version of the solar cell in a flat panel form. 我做了一个更加便携的版本的太阳能电池在平板形式。I used the clear plastic top from a plastic CD jewel case as the window, and lots of silicone rubber glue to both attach the pieces together and to insulate them from each other.我用了透明塑胶上了从塑料CD显示珠宝箱,很多硅橡胶胶将碎片粘合起来,都和人免遭对方。
The first step is to make a cuprous oxide plate like we did in the first solar cell. 第一步是要使氧化亚铜板,就像以前在第一个太阳能电池。This time I sanded one corner clean all the way down to the shiny copper, and soldered an insulated copper wire to it for the negative lead.这一次我用砂纸一个角落打扫所有的角度下闪闪发亮的铜,焊接一个绝缘铜导线是负面的领先。
The positive plate is a U shaped piece cut from the copper sheeting, a little bit larger than the cuprous oxide plate, with the cutout portion of the U a little bit smaller than the cuprous oxide plate. 积极的板是一个U形片剪从铜薄膜,大一点的氧化亚铜板,抠图部分你有点小于氧化亚铜板。Another insulated copper wire is soldered to one corner of the U.另一个绝缘铜导线是焊接到你的一个角落里。
The first step in construction is to glue the U shaped copper plate to the plastic window. 第一步,在建设就是要粘U形的铜板到塑性变形的窗口。Use plenty of silicone glue, so the saltwater won't leak out. 用到大量的硅酮胶,所以盐水不会泄露出去。Make sure that the solder connection is either completely covered with glue, or is outside of the glue U, as shown in the photo (completely covered in glue is best).确保焊接连接,要么是完全覆盖了胶、或在外面胶水你,显示在这张照片(满胶水是最好的)。 The photo below shows the back side of the solar cell (the side not facing the sun) at this point in the construction.这张照片下面显示背面太阳能电池(边不能面对太阳)在这一点上,在建设。
The photo below shows the front side of the solar cell (the side that will face the sun) at this point in the construction. 这张照片下面显示正面太阳能电池(边,将面对太阳)在这一点上,在建设。Notice that the silicone glue does not completely cover the copper, since some of the copper must eventually be in contact with the saltwater.注意到硅酮胶不完全覆盖铜,由于一些铜最终一定会在与盐水。
The next step is to lay a good size bead of glue onto the U shaped clean copper plate. 下一步是奠定了良好的大小珠的胶水在U形干净的铜板。This layer will act as an insulator between the clean copper plate and the cuprous oxide plate, and must be thick enough to leave some room for the saltwater. 这层将作为绝缘体之间的干净的铜板和氧化亚铜板,必须厚度足以留下一些空间,给盐水。Again, not all of the copper is covered, so there will be plenty of copper in contact with the saltwater.再次,并非所有的铜盖上了,将有许多的铜接触盐水。 Gently press the cuprous oxide plate onto this layer of glue. 轻压到氧化亚铜板的这层胶水。You should press hard enough to make sure the glue seals off any gaps, but not so hard that the two plates touch.你应按难以确定胶封堵间隙,但不是非常努力,两个盘子的联系。
The photo below shows the back side of the solar cell (the side not facing the sun) at this point in the construction.这张照片下面显示背面太阳能电池(边不能面对太阳)在这一点上,在建设。
The photo below shows the front side of the solar cell (the side that will face the sun) at this point in the construction. 这张照片下面显示正面太阳能电池(边,将面对太阳)在这一点上,在建设。Note that I added extra glue to form a funnel at the top to allow the saltwater to be added.请注意,我增加额外的胶水,形成了一个漏斗榜首让盐水被补充说。
You can click on the photo above to get a bigger picture.你可以用鼠标点击上面的照片得到一个更大的图景。 Not shown in the photo is a generous extra bead of glue all around the outside of the plates, to ensure that no saltwater will leak out. 未出现在照片是一个慷慨的额外的一连串的胶在以外的盘子,确保不盐水会泄露出去。Allow the glue to cure before going on to the next step.允许胶水治疗之前进行到下一阶段。 Next, use a large eyedropper to add the saltwater. 其次,使用大眼药加入盐水。Fill the cell up almost to the top of the copper plate, so it almost spills out. 把细胞几乎至最高的铜板,所以它几乎泄漏出来。Then seal the funnel with another generous bead of glue, and allow the glue to cure at least a half hour.然后密封了漏斗与另一个慷慨的一连串的胶水,让胶水治疗至少半小时。
In the photo above you can see the flat panel solar cell in action in the bright sun. 上面图片中你可以看到的平板太阳能电池,在行动在明亮的阳光。It is delivering about 36 microamperes of current. 它为36 microamperes的电流。You can also see the extra bead of glue around the edges of the plates, and filling the top of the funnel.你也可以看到额外的一连串的胶板的边缘,并填充漏斗的顶端。
Finally, another shot of the author's shadow. 最后,又喝了作者的影子。Note that the meter now reads about 4 microamperes, since no sunlight is falling on it.注意仪表现在阅读能力大约4 microamperes,因为没有阳光正在下降。
A note about power一张纸条,论述了电力Many readers were jumping straight to this page without reading the previous project, so I am repeating this note here:许多读者直接跳这一页没有阅读以前的项目,所以我重复这个注意到这里: The cell produces at most about 50 microamps at 0.25 volts.在大部分的细胞产生约50微安在0.25伏特。 The 0.0000125 watts (12.5 microwatts) is for a 0.01 square meter cell, or 1.25 milliwatts per square meter. 这0.0000125瓦(12.5 microwatts)是为0.01平方米的细胞,(125毫瓦的功率超过130平方米。To light a 100 watt light bulb, it would take去点燃一100瓦的灯泡,将需要80,000 square meters8万平方米of cuprous oxide for the sunlit side, and 80,000 square meters of copper for the dark electrode. 的氧化亚铜为深谷,旁边,8万平方米的铜黑暗的电极。To run a 1,000 watt stove, you would need 800,000 square meters of cuprous oxide, and another 800,000 square meters of plain copper, or 1,600,000 square meters all together. 运行1000瓦炉,你需要80万平方米的氧化亚铜,另一个80万平方米的平原铜、或160平方米结合在一起。If this were to form the roof of a home, each home would be如果出现这种形式的屋顶,每个家庭有家,282 meters long and 282 meters wide282米长和282米宽, assuming all they needed electricity for was one stove.,假设所有他们需要电是一个炉子。 There are有17,222,256.7 square feet17,222,256.7平方英尺in 1,600,000 square meters. 在160余万平方米。If copper sheeting costs $5 per square foot, the copper alone would cost $86,110,283.50 USD. 如果铜薄膜要花费5美元,每平方英尺铜就将花费$ 86,110,283.50美元。Making it one tenth the thickness can bring this down to $8,611,028.35. 使它成为一个可以把这十厚度下8,611,028.35美元。Since you are buying in bulk, you might get it for half that, or about $4,300,000.00.既然你买散装的,你很有可能得到它一半,4,300,000.00美元左右。 If you used silicon solar panels costing $4 per watt, you could run the same stove for $4,000.00. 如果你使用的硅太阳能电池板耗资4 %瓦特,你可以运行,同时另起炉灶,为$ 4,000.00。But the panels would only be about 10 square meters.但面板将会约10平方米。 Or, for about a dollar, you can build a solar stove out of aluminum foil and cardboard. 或者,约一美元,你可以建立一个太阳能炉灶出的铝箔纸和纸板。For about $20, you can build a very nice polished aluminum parabolic solar cooker.大约20块钱,你可以建立一个很好的抛光铝抛物型太阳能炊具。 |
