33、ghtSolar photovoltaic thermal energy systems,or PVTs, generate both heat and electricity, but until now they havent been very good at the heat-generating part compared to a stand-alone solar thermal collector. Thats because they operate at low temperatures to cool crystalline silicon solar cells, wh

34、ich lets the silicon generate more electricity but isnta very efficient way to gather heat.Thats a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And its also a space problem: photovoltaic cells can take up

35、all the space on the roof, leaving little room for thermal applications.In a pair of studies, Joshua Pearce, anassociate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Giro

36、tra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queens University, Canada.Most solar panels are made with crystalline silicon, but you can also make solar cells out of amorphous silicon, commonly known as thin-film silicon. They dont create as much electricity, but t

37、hey are lighter, flexible, and cheaper. And, because they require much less silicon,they have a greener footprint. Unfortunately, thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.“That means that their efficiency drops when you expose t

38、hem to light pretty much the worst possible effect for a solar cell,” Pearce explains,which is one of the reasons thin-film solar panels make up only a small fraction of the market.However, Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film sili

39、conin a new type of PVT. You dont have to cool down thin-film silicon to make it work. In fact, Pearces group discovered that by heating it to solar-thermal operating temperatures, near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When

40、they applied the thin-film silicon directly to a solar thermal energy collector,they also found that by baking the cell once a day, they boosted the solar cells electrical efficiency by over 10 percent.31. PVTs are not efficient inA. creating electricity.B. cooling silicon solar cells.C. generating

41、heat.D. powering solar thermal collectors.32. One of the problems PVTs have is thatA. their thermala pplications are costly.B. they are too expensive to afford.C. it is hard to fix them on the roof.D. they occupy too much space.33. Which of the following is NOT mentioned as an advantage of thin-film

42、 silicon solar cells?A. They are flexible.B. They are less expensive.C. They are electrically efficient.D. They are environment friendly.34. Thin-film solar panels do not sell well on market becauseA. they do not work well if exposed to light.B. their advantages are not well-recognized.C. they need

New techniques have been developed to produce thin-film silicon.B Thin-film silicon works efficiently at low temperature.C Thin-film silicons electrical efficiency improves when heated up.D Anew materi

44、al enlarging the Staebler-WronsKi effect has been created.譯文：第十三篇 更有效的太陽能系統(tǒng)：更多熱量，更強燈光太陽能光伏熱能系統(tǒng)，也叫PVT，能夠生成熱量和電能。與太陽熱能單機收集器相比，傳統(tǒng)太陽能光伏熱能系統(tǒng)在轉(zhuǎn)換熱能方面效率不是很高。原因是，為了使晶體硅太陽能電池冷卻，該系統(tǒng)在低溫下工作。因此，硅體能產(chǎn)出更多的電能，卻不能有效地產(chǎn)生熱量。第一，經(jīng)濟問題。好的太陽能熱水系統(tǒng)比太陽能電力系統(tǒng)收集的能量更多，而且成本低得多。第二，空間問題。光電管占去屋頂?shù)乃械目臻g，幾乎沒有空間留給熱能的產(chǎn)出。在一項研究中，材料科學與工程副教授Josh

45、ua Pearce找到了一個解決方案：用另外一種硅制成PVT來解決效能問題。他的合作者有：來自加利福尼亞ThinSilicon的Kunal Girotra和加拿大皇后大學的Michael Pathak和Stephen Harrison。大部分太陽能電池板是由晶體硅制成，但是，你也可以用非晶硅制成太陽能電池，這種非晶體硅通常被叫作薄膜硅。它們不能產(chǎn)生那么多的電能，但是更亮、更靈巧、成本更低。而且，由于它們需要的硅較少，它們更環(huán)保。不幸的是，薄膜硅太陽能電池易受SWE效應攻擊(在光的照射下，非晶硅氫的導電性短時間內(nèi)顯著衰退，這種特性被稱為SWE效應)。“當被暴露在光線下，那就意味著它們的能效會降低

46、這幾乎是太陽能電池最可能糟糕的效應?！盤earce解釋道。這就是薄型太陽能板只占有一少部分市場的原因。然而，Pearce和他的團隊把薄膜硅合成為一種新型的PVT，可以克服或繞過SWE效應。這種方法可以不用冷卻薄膜硅而讓它們產(chǎn)生效能。事實上，Pearce團隊發(fā)現(xiàn)，通過把薄膜硅加熱到太陽熱能操作溫度，即臨近水的沸點，可以把它制成較厚的電池，從而可以遏制SWE效應。當把薄膜硅直接應用到太陽熱能集熱器時，他們也發(fā)現(xiàn)，如果一天把太陽能電池加熱一次，那么太陽能的電力效能會增加10%。第二篇 Whats killing the BatsFirst it was bees. Now it is bats. B

47、iologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats (Myotis lucifugus,) but other species, such as the long-eared bat, the small-footed ha

48、t, the eastern pipistrelle, and the Indiana bat have also been affected. In some caves, more than 90 percent of the bat populations have died.One possibility is disease. A white fungus (真菌)known as fusarium has been found on the noses of both living and dead bats. However, scientists dont know If th

49、e fungus is the primary cause of death, a secondary cause of death, or not a cause at all, but the result of some other conditions.Another possible cause is a lack of food. For example, bats typically eat a large number of moths (蛾), and in some states such as New York, the number of moths has been

50、declining in recent years. If bats cant eat enough food, they starve to death.Still other scientists believe that global warming is to blame. Warmer temperatures in recent years have been waking up hibernating (冬眠)bats earlier than usual. If bats break their hibernation at the wrong time, they might

51、 not find their expected food sources. The weather might also turn cold again and weaken or kill the bats.Scientists might not agree on the causes of the bat die-off, but they do agree on the consequences. Bats are an important predator of mosquitoes; a single brown bat can eat 1,000 or more insects

52、 in an hour. They also eat beetles and other insects that damage plant crops. If there arent enough bats, damage will be great from the insects they eat While bats live a long time for their size 一 the little brown bat can live for more than 30 years 一 a female bat has only one baby per year, so bat

53、 populations grow slowly. Many bat species in the United States are already protected or endangered.How can you help? Do not disturb sleeping or nesting bats. If you discover bate that seem to be sick or that are dead, contact your local Fish& Wildlife Department with the details. However, be carefu

54、l not to touch the animals.36. What is the main idea of this passage?A. All species of bats in North America are dying.B. Scientists already know the cause of the deaths of batsC. The bat deaths are a serious problem.D. There are many possible causes of the deaths of bats.【答案】D【解析】文章的題目是“是什么殺死了蝙蝠”。第
