In a breakthrough, scientists have developed a new low cost, efficient and environment-friendly solar cell that uses tin instead of the hazardous lead. Researchers from Northwestern University are among the first to create a solar cell that uses a structure called perovskite, with tin as the light-absorbing material instead of lead. "Exculding the use of lead is a quantum leap in the process of creating a very promising type of solar cell called a perovskite," said Mercouri G Kanatzidis, an inorganic chemist with expertise in dealing with tin. "Tin is a very viable material, and we have shown that it works as an efficient solar cell," said Kanatzidis. Lead perovskite has achieved 15 per cent efficiency and tin perovskite should be able to match - and possibly surpass - this level of efficiency, researchers said. Perovskite solar cells are being touted as the "next big thing in photovoltaics" and have reenergised the field.
Finance experts expect more initial public offerings (IPO) in the wind energy sector in 2014 after a year in which half a dozen companies on both sides of the Atlantic successfully raised nearly $2.3 billion by tapping the public equity markets. "It is hard to really predict how many will come out of the gate and actually get done. But there are 10-20 companies out there working on it, wondering if this is good source of low-cost capital for them and if they have what it takes to make a placement like this," says Michael Eckhart, global head of environmental finance with Citigroup. British fund Greencoat UK Wind started a wave of IPOs in March 2013, raising £260 million ($433 million). NRG Yield in the US and the Renewables Infrastructure Group (TRIG) in the UK followed in July with offerings of $431 million and £300 million, respectively. Canada's TransAlta Renewables completed a C$221 million (US$200 million) share sale in August, California-based Pattern Energy raised $352 million in October, and the UK's Infinis rounded up the year with a £234 million share sale in November.
