Rapid increase in the deployment of photovoltaic installations since the beginning of the century has led to the global capacity exceeding 220GW today. Projections foreseeing growing solar panel deployment rates show that photovoltaic installations will be an important asset in developing a more sustainable world economy. Yet, increasing deployment rates will lead to large volumes of waste photovoltaic modules in the future and large volumes of decommissioned panels can be expected by the middle of this century. Efficient end-of-life treatments will be needed to recover valuable components. Perovskite solar cells were first reported half a decade ago and improvements in efficiency of laboratory scale devices have been achieved at an unprecedented pace. This Perspective discusses some important environmental, regulatory, and practical aspects potentially arising at the end of life of decommissioned perovskite solar cells. With increasing PV deployment rates, resulting waste volumes can be foreseen with a 20- to 30-year lag.

自本世纪初以来，光伏装置的部署迅速增加，导致今天的全球容量超过220GW。可以预见的太阳能电池板部署率的增长预测表明，光伏装置将是发展更可持续的世界经济的重要资产。然而，越来越高的部署率将导致将来产生大量的废弃光伏组件，并且预计到本世纪中叶将会有大量的退役面板。需要有效的报废处理来回收有价值的成分。钙钛矿型太阳能电池是六十年前首次报道的，实验室规模的设备效率得到了前所未有的提高。本《观点》讨论了一些重要的环境，法规，退役的钙钛矿太阳能电池寿命终止时可能产生的实际问题。随着光伏部署率的提高，可以预见到产生的废物量将有20至30年的滞后。
