摘要

Ultra-thin crystalline silicon (c-Si) solar cells are that they are not only deemed to dramatically reduce material usage but also offer the potential of achieving higher efficiency due to higher open-circuit voltages. In this talk, we will demonstrate that an 8.5 micro ultrathin c-Si tandem solar cells, with the emphasis on the fabrication processes and the inverted nanopyramid light trapping structure. First, we will show how to obtain the ultrathin c-Si film and then transfer it to the rigid substrate with the aid of anodic bonding process; Second, an inverted nanopyramid light trapping structure, which is developed to adapt to the ultrathin device design, is also demonstrated as an effective light trapping scheme in the ultrathin c-Si tandem solar cells; Third, the concept of diffractive intermediate layer is also presented based on the nanoscale light trapping structure implemented in the c-Si tandem solar cells.  At the last part of this talk, we will also show some of our progress on the development of large-scale and stable perovskite solar cells.
