Finite resources of fuel energy, global warming and climate change, sustainability and green energy supply are the main drives for solar cell technology. Solar cell market has witnessed an exponential growth from 1992 to 2017 and it cumulative capacity reached about 401Gigawatts estimated to be sufficient for about 2.1% of global electricity demand. However, a solar cell efficiency, the ability of the cell to convert sunlight to electricity, has not been improved more than about 30% over the last 45 years of active research on solar cell technology. Improving the conversion efficiency will not only affect the cost but also compensate the intermittency of sunlight to store electricity. ****In this project, Majedi's group with a support of Callisto Integration will design a new solar cell based on superconducting ceramic on top of conventional silicon solar cell to increase the conversion efficiency beyond the physical limit of silicon single junction that is about 32%. This design is based on ultra wide band optical absorption on YBCO ceramic and its cryogenic operation to mitigate the thermal losses in conventional solar cell. This new solar cell will lead the researchers to come up with new physics and engineering design for the new generation of silicon solar cells.**

燃料能源有限、全球变暖和气候变化、可持续发展和绿色能源供应是太阳能电池技术的主要驱动力。从1992年到2017年，太阳能电池市场经历了指数级的增长，累计装机容量达到约401千兆瓦，估计足以满足全球约2.1%的电力需求。然而，在过去45年积极研究太阳能电池技术的过程中，太阳能电池的效率，即电池将阳光转化为电能的能力，并没有提高超过30%。提高转换效率不仅会影响成本，还会补偿阳光存储电能的间歇性。*在该项目中，Majedi的团队将在Calisto集成的支持下，在传统硅太阳能电池的基础上设计一种基于超导陶瓷的新型太阳能电池，以提高转换效率，使其超过硅单结约32%的物理限制。该设计基于YBCO陶瓷的超宽带光吸收和低温工作，以减少常规太阳能电池的热损失。这种新的太阳能电池将带领研究人员为新一代硅太阳能电池提出新的物理和工程设计。**
