Better Solar Energy Systems: More Heat, More LightSolar photovoltaic thermal energy systems,or PVTs,generate both heat and electricity,but until now they haven't been very good at the heat-generating part compared to a stand-alone solar thermal collector. That's because they operate at low temperatures to cool crystalline silicon solar cells,which lets the silicon generate more electricity but isn't a very efficient way to gather heat.That's 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 it's also a space problem:photovol-taic cells can take up all the space on the roof,leaving little room for thermal applications.In a pair of studies,Joshua Pearce,an associate professor of materials science and engineer-ing,has devised a solution in the form of a better PVT made with a different kind of silicon.His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen's 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 don't create as much electricity, but they 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 them 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 silicon in a new type of PVT. You don't have to cool down thin-film silicon to make it work.In fact,Pearce's 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 they applied the thin-fulm silicon directly to a solar thermal en-ergy collector,they also found that by baking the cell once a day,they boosted the solar cell's e-lectrical efficiency by over 10 percent. Which of the following is NOT mentioned as an advantage of thin-film silicon solar cells?A:.They are electrically efficient.B: They are less expensive.C:.They are flexible.D: They are environment friendly.

Google's Solar Energy Gambit（策略）Google is making its largest investment yet in clean energy,setting up a $280 million fund to finance home solar rooftop（屋顶）installations.The search giant announced today it was teaming up with the Silicon Valley's Solar City一a company chaired by Paypal co-founder and Tesla Motors executive Elon Musk一in an effort to break down the biggest barrier to solar energy adoption:the cost."It's a great way to support installations going into more homes,"said Google spokesperson Parag Chokshi.The $280 million fund is the largest fund ever created for residential solar in the United States,according to Solar City,which has raised a total of$I.28 billion in financing capacity during its five-year history.Google over the past several years has invested in large,utility-scale wind and solar,enhanced geothermal（地热）energy,and other renewable energy projects,for a grand total of more than $680 million in the sector. But today's deal is not only Google's largest foray（突袭）into the sector, it is its first investment in distributed energy. Based in San Mateo,California,less than 20 miles north of Google's Mountain View headquarters,Solar City describes itseff as a solar power service provider. The idea is that people want affordable,clean energy一but they often can't afford to buy a photovoltaic system upfront. Solar City is one of a number of companies that have attempted to help people overcome that cost hurdle（障碍）by leasing,instead of owning their rooftop solar systems.Solar City's leases and power-purchase agreements to homeowners,businesses,and schools promise a lower monthly electricity bill(including a set payment to Solar City in addition to utility payments)than customers would get with their usual electricity from the grid.Solar City not only finances these photovoltaic projects,but also designs,installs,monitors,and maintains the systems. Recently,since buying the assets of a company called Business Solutions last year,Solar City has also begun offering energy audits and small home improvements(like installing programmable thermostats)that can make a big difference in energy use.Until now,Solar City has financed most of its 15,000 projects through banks,Chief Executive Lyndon Rive said in an interview. But the problem is only about a half dozen banks are doing solar financing,he said.So in order for Solar City's model to achieve"true scale,"it must"unleash the available capital of corporate America,"he said.Rive is hopeful that Google's move today will set an example for other corporations to make similar investments. Google is the biggest clean energy company in the world.A:Right B:Wrong C:Not mentiond
