We propose that 1 + 1 + 1 triple-junction solar cells can provide an increased efficiency, as well as a higher open circuit voltage, compared to tandem solar cells.

A high-performance semitransparent tandem solar cell that uses solutionprocessed graphene mesh and laminated Ag NW as a transparent anode and cathode, respectively, is demonstrated. The laminated top electrode can be deposited without causing any damage to the underneath organic solar cells. Power conversion effi ciencies of 8.02% and 6.47% are obtained when the light is projected from the solution-processed graphene mesh and laminated AgNW, respectively. The performance of the tandem cell is found to be comparable to a tandem solar cell fabricated using commercially available indium tin oxide. These fi ndings offer a high-performance device and open a new pathway in searching for a potential replacement to the frequently used transparent conducting electrodes.

A molecular cross-linking approach of the perovskite grains combined with amine-based surface passivation leads to hysteresis-free perovskite transistors.

We demonstrate an ITO-free tandem polymer solar cell employing Au-doped single layer graphene nanoribbons.
