With the advent of global warming, rapidly increasing demand for energy, and concerns over the security of supply of traditional carbon based fuels the requirement for alternative, sustainable energy sources is recognised throughout the world. Photovoltaics (PVs) harvest electrical energy directly from sunlight, delivering power at the point of use and are potentially a major component of the long term solution to this growing challenge. The current market is dominated by first generation Si devices which offer good power conversion efficiencies and operational lifetimes, but remain too expensive for major deployment. Second generation thin film technologies based on materials such as cadmium telluride and copper indium gallium diselenide are also showing significant promise, however the lower device efficiencies and relatively high processing costs means that market penetration remains low. Consequently, there is a rapidly growing worldwide focus on the development of new third generation PV technologies which offer the prospect of significantly improved performance and/or low cost manufacture, thus helping to accelerate commercial exploitation and large-scale deployment. New PV technologies will require innovations in materials, concepts and devices and the unique and flexible nature of Platform Grant funding will help the Warwick group tackle this important strategic challenge.

随着全球变暖的到来，对能源的需求迅速增加，以及对传统碳基燃料供应安全的担忧，对替代、可持续能源的需求在全世界都得到了认可。光伏（pv）直接从阳光中获取电能，在使用点提供电力，可能是解决这一日益增长的挑战的长期解决方案的主要组成部分。目前的市场由第一代硅器件主导，它们提供了良好的功率转换效率和工作寿命，但对于大规模部署来说仍然过于昂贵。基于碲化镉和双硒化铜铟镓等材料的第二代薄膜技术也显示出巨大的前景，但较低的设备效率和相对较高的加工成本意味着市场渗透率仍然很低。因此，世界范围内对新第三代光伏技术发展的关注迅速增长，这些技术提供了显著改善性能和/或低成本制造的前景，从而有助于加速商业开发和大规模部署。新的光伏技术将需要材料、概念和设备的创新，而平台资助的独特和灵活的性质将帮助华威集团应对这一重要的战略挑战。
