Design Rules for Donors in Bulk‐Heterojunction Tandem Solar Cells�Towards 15 % Energy‐Conversion Efficiency

The study we present here aims at evaluating the efficiency of tandem organic solar cells expectable by stacking two materials, comparing this efficiency to the one that could be achieved by single cells based on these materials, and identifying the characteristics of the materials to be stacked to...

Description
Summary:The study we present here aims at evaluating the efficiency of tandem organic solar cells expectable by stacking two materials, comparing this efficiency to the one that could be achieved by single cells based on these materials, and identifying the characteristics of the materials to be stacked to achieve efficiency higher than the single cells. In other words, we intend to clarify the potential of organic tandem solar cells and the expectations that one might have by realizing some.
