Solution-processed solar cells utilising Organic or Perovskite absorber materials are a low-cost alternative to established and emerging inorganic technologies. Printing and coating techniques provide an affordable and scalable route to manufacture these Organic or Perovskite solar cells from solution and under atmospheric conditions.

SPECIFIC (Swansea University), along with other academic and commercial institutions have demonstrated significant success with the solution-processing of Organic and Perovskite materials for the generation of electrical power. A number of printing and coating techniques have been demonstrated on rigid glass, and flexible substrates such as plastic and metallic foils. The printing and coating techniques are typically employed as batch processes on a series of discrete substrates. This poster presents recent work to translate developments in batch processing on flexible substrates into a continuous process using a Roll 2 Roll (R2R) coating line (Coateema Smart-Coater). Preliminary findings and developments are described as the journey towards a device fully-manufactured by R2R processing continues.

This R2R approach allows high-throughput manufacturing onto flexible substrates, a prospect of significant importance to the commercialisation of low-cost large-area solar cells by solution processing.
