Abstract:Conventional silicon solar cells are bulky and inflexible, but researchers in the Rogers Group of the Department of Materials Science and Engineering, University of Illinois at Urbana-Champaign came up with a new method of creating arrays of highly efficient flexible silicon solar cells. This project seeks to further improve these solar cells by changing and optimizing the designs of the solar cell geometry. There are two new designs for the improved solar cells. The first design has the emitter on the bottom layer of the microcells to eliminate metal shadowing and thus to increase the cell efficiency. The second design features a plate-like geometry that makes metal interconnections between cells unnecessary. In this report I will discuss the procedures of fabricating these devices, present the results of these new solar cells, and compare the results with those of previous designs.
