The ever increasing demand for clean environmentally friendly sources of energy has provided a strongimpetus for developing commercially a viable photovoltaics (PV) industry; in particular, one in which the costof electricity from PV equals that from the grid (i.e., so called grid parity) by improving solar cell and moduleefficiency and reducing cell/module costs. The PV roadmap envisions meeting 5% of the global energy needsby 2010 and 11% by 2030,the bulk of which has to be achieved by improvements in current commercialSilicon solar cell technology, before alternative technologies can develop and mature. This requires increase inthe efficiency of Silicon cells from the present level of 16-20% to about 23% by 2020 and about 25% by 2030,in addition to continued cost reduction.Our industrial partner, Canadian Solar Inc., is a leading PV manufacturer with over $1.6 billion revenue in2013. To keep the market position meeting the demands of lower cost, better material utilization and higherefficiencies, CSI urgently needs to transition to newer cell designs including optimized front contact patternsfor reduced shading and resistive losses, inter-digitated back-contact (IBC) cells and hetero-structured celldesigns.The work proposed here combines state-of-the art computational methodologies for optimization of deviceperformance and resource utilization with high-resolution characterization techniques to develop new PV celldesigns that could be utilized in the current and planned manufacturing facilities of CSI. Device designs will bevalidated by measurements on prototypes produced by CSI, in collaboration with CSI engineers. The projectwill provide a unique milieu for the training of highly qualified personnel for our Canadian industrial partner,and help keep Canada at the forefront of the burgeoning industry.

对清洁环境友好的能源的需求不断增长，为在商业上开发一个可行的光伏（PV）行业提供了强大的建议。特别是，从PV发电的成本等于通过改善太阳能电池和模量质量并降低电池/模块成本来从网格（即所谓的网格均衡）中等同。 PV路线图设想在2010年到2010年的全球能源需求的5％，到2030年为11％，在替代技术可以开发和成熟之前，必须通过改进当前的商业硅太阳能电池技术来实现其中的大部分。这需要将硅细胞的效率从目前的16-20％提高到2020年约23％，到2030年，硅细胞的效率除了继续降低成本。 2013年收入超过16亿美元的制造商。为了保持市场位置满足较低成本，更好的物质利用和Higherefficiencies的需求，CSI紧急需要过渡到更新的细胞设计，包括优化的前触点图案减少阴影和电阻性损失，相互依赖的背部接触（IBC）和Hetero - 结构化的CellDeSign。此处提出的工作结合了最先进的计算方法，以优化设备的性能和资源利用率和高分辨率表征技术，以开发可在CSI的当前和计划的制造设施中使用新的PV CellDesigns。设备设计将通过与CSI工程师合作生产的原型的测量值来进行攻击。该项目将为我们的加拿大工业合作伙伴培训高素质的人员提供独特的环境，并帮助将加拿大保持在新兴行业的最前沿。
