Report on carbon-electrode based PSC with PCE ≥ 21% and roadmap to PCE ≥ 23% with long-term stability

This deliverable is related to T2.3 and will summarize the developments and results achieved to realize high performance (PCE 21%) perovskite solar cells based on carbon electrodes. Taking into account results from WP1 on novel materials, a roadmap towards long-term stable carbon-electrode based cells with PCE 23% will be presented.
