Advanced Energy Materials Top 40 for August 22, 2012

This week’s top three are all newcomers to the Top 40 table: at #1, Andreas Stein and coworkers review porous materials for lithium ion battery electrodes. They show how porosity affects key performance parameters such as rate capabilities, cycling stability or capacities. Second place goes to David Mitzi and colleagues at IBM Watson for their report on record-breaking CZTSSe solar cells with 11% power conversion efficiency, and third come Stubhan and Brabec et al. with their work on polymer solar cells incorporating a tungsten oxide hole extraction layer that improves fill factor and and open circuit voltage.

Another noteworthy new entrant is Taiho Park’s group with its findings of size-selective ion transfer through nanoporous polymer nanocomposites. At #7, they illustrate how pore size tuning helps improve the performance of dye-sensitised solar cells.
