Why, despite considerable R&D efforts and significant translational investment over the past 20 years, has the technology of solution-processed thin film solar cells not become a commercial reality? The manufacturing cost-to-power conversion efficiency ratio seems persuasive, as do the energy payback and embodied energy metrics. As new perovskite-based semiconductors achieve impressive efficiencies and organic semiconductors enjoy a resurgence, the lab-to-manufacturing translation and scaling questions require urgent attention. This comment addresses the challenges in solution processable photovoltaic technologies faced by scientists and engineers in addressing these questions, and highlights the concept of thick junctions as a promising solution.

下一代溶液处理的有机和钙钛矿太阳能电池的规模扩展。

在过去的20年中，尽管进行了大量的研发工作和大量的转换投资，为什么固溶处理的薄膜太阳能电池技术还没有成为商业现实呢？制造成本/功率转换效率比，能源回收和具体的能源指标都具有说服力。随着新型基于钙钛矿的半导体实现令人印象深刻的效率，而有机半导体又开始复苏，从实验室到生产的平移和缩放问题迫切需要关注。该评论解决了科学家和工程师在解决这些问题时面临的解决方案可加工光伏技术的挑战，并强调了厚结的概念是一种有前途的解决方案。
