Unconventional computing and artificial photosynthesis seem to be completely unrelated fields of research. However, both technologies try to sustain the development of our civilization despite the flood of information and limited energy resources. In this review, we will show that the same materials – namely organic–inorganic metal halide perovskites and other iodine-based semiconductors – are materials of choice for both fields of scientific and technological activity. This contribution reviews the most up-to-date achievements in the fields of artificial photosynthesis and neuromimetic unconventional computing that utilize metal halide perovskites or other heavy metal-halogen compounds as active materials. Recent advances about photocatalysis and perovskite photovoltaics are also added to demonstrate the versatility of the applications that result from the peculiar geometric and electronic structures of iodine-based semiconductors.

非常规计算和人工光合作用似乎是完全无关的研究领域。然而，尽管信息泛滥且能源资源有限，但这两种技术都试图维持我们文明的发展。在这篇综述中，我们将显示相同的材料，即有机-无机金属卤化物钙钛矿和其他基于碘的半导体，是科学技术活动领域的首选材料。该贡献回顾了利用金属卤化物钙钛矿或其他重金属卤素化合物作为活性材料的人工光合作用和模拟神经的非常规计算领域的最新成就。
