TL;DR: Flexible perovskite based solar cells with power conversion efficiencies of 7% have been prepared on PET based conductive substrates as discussed by the authors, demonstrating their suitability for roll to roll processing.

TL;DR: In this article, a roll-to-roll (R2R) processed organic functional layer was applied to the indium tin oxide (ITO)-free organic solar cells.

TL;DR: In this paper, an alternative transparent electrode consisting of a layer stack of aluminum doped zinc oxide and a thin silver layer was proposed for future industrial production processes of organic solar cells, which will rely on a high-throughput of flexible substrates to achieve low cost of the final product.

TL;DR: In this paper, a reproducible large-area procedure was developed to replace the traditional 1 μm printed space layer with an ultra-thin dense 40 nm sputtered Al2O3 which acts as a highly electrically insulating layer preventing ohmic shunts.

TL;DR: In this paper, a photonic color concept for integrated photovoltaic modules is introduced to achieve an improved angular independent color effect, suitability for module integration, and compatibility with industrial production processes, while maintaining high module efficiencies.
