Solar cell costs have dropped dramatically over the last decade. According to the International Energy Agency, "solar is now the cheapest source of electricity in most countries” and “now offer some of the lowest cost electricity ever seen”, with their installed capacity “set to triple before 2030 under current and proposed policies with the potential to grow much faster”. This talk will describe how the cells work, why the costs have fallen so quickly, how much further cost reduction is likely and the role solar can play in displacing fossil fuel use, decreasing carbon dioxide emissions on a timeline consistent with constraining global temperature rise to manageable levels.
近十年来，太阳能电池的成本急剧下降。据国际能源署报道，“在大多数国家，太阳能现在是最便宜的电力来源”并且“提供了前所未见的低成本电力”，“依据现行和已经提出的政策，太阳能装机容量将在2030年前增加两倍，并有可能实现更快增长”。本次讲座会讨论太阳能电池的工作原理、成本快速下降的原因、进一步成本下降的空间，以及太阳能在逐步替代化石燃料、降低二氧化碳排放量以稳定全球温度上升方面的作用。
BIOGRAPHY
Green was born in Brisbane on 20 July 1948,[10] and was educated at the selective Brisbane State High School, graduated from University of Queensland and completed his PhD on a Commonwealth Scholarship at McMaster University in Canada, where he specialised in solar energy. In 1974, at the University of New South Wales, he initiated the Solar Photovoltaics Group which soon worked on the development of silicon solar cells.[3] The group had their success in the early 80s through producing a 20% efficient silicon cell, which now has been improved to 25%.
格林1948年7月20日出生于布里斯班，[10]，在布里斯班州立中学接受教育，毕业于昆士兰大学，并在加拿大麦克马斯特大学（McMaster University）获得英联邦奖学金，在那里他专攻太阳能。1974年，在新南威尔士大学，他创立了太阳能光伏小组，该小组很快就致力于硅太阳能电池的开发。[3]该小组在80年代初取得了成功，生产了效率为20%的硅电池，现在已提高到25%。
