Within the context of a fast growing demand of renewable electrical energy, GreenPHOTOSOLV project deals with current development challenges of printed photovoltaic technologies through the novel application of a systemic approach based on reverse engineering. The project addresses two major issues in solution-processed photovoltaic technologies, namely the limited understanding of the role of solvents on the device performance and the need to reduce the significant impact of solvents on human health and the environment. Organic and perovskite photovoltaics have the potential to be fabricated in large scale with low production costs, but the transition progress is slowed by the unfavorable indicators of the current used mostly toxic solvents. However, the selection of solvents with reduced environmental, health and safety impact is currently done empirically, based mainly on accumulated experimental knowledge, with limited effectiveness. The current incomplete understanding of solvent/absorber material interactions is partly responsible for this limitation. Therefore, by implementing a proficient computer assisted molecular design method based on a better understanding of the effect of the solvent on the processing of the absorber layer using organic and perovskite absorber materials, the project will allow a more rational and efficient design of green bio-sourced substitution solvents and will contribute to the generation of renewable electrical energy in a more environmentally friendly and cost-efficient way. Within the project, experimental methods and processes will be optimized in the course of the all fabrication steps (chemical synthesis of absorber materials, thin-film deposition and device assembling) and combined with predictive properties models to produce new fundamental and exploratory knowledge. To achieve this purpose, the proposed consortium brings together complementary competences that cover the project needs in chemistry, chemical engineering, material sciences and device physics. Overall, the results of the project are intended to provide new concepts breaking with existing paradigms and to help in the future energy transitions with improved solution-based solar cells.

在可再生电能需求快速增长的背景下，GreenPHOTOSOLV 项目通过基于逆向工程的系统方法的新颖应用来应对印刷光伏技术当前的发展挑战。该项目解决了溶液加工光伏技术中的两个主要问题，即对溶剂对器件性能的作用的了解有限，以及需要减少溶剂对人类健康和环境的重大影响。有机和钙钛矿光伏电池具有大规模生产、生产成本低的潜力，但由于目前使用的大多数有毒溶剂的不利指标，这一转变进程被减缓。然而，目前主要基于积累的实验知识凭经验选择对环境、健康和安全影响较小的溶剂，效果有限。目前对溶剂/吸收剂材料相互作用的不完全理解是造成这种限制的部分原因。因此，通过在更好地了解溶剂对使用有机和钙钛矿吸收材料的吸收层加工的影响的基础上实施熟练的计算机辅助分子设计方法，该项目将能够更合理、更有效地设计绿色生物源替代溶剂，并将有助于以更环保和更具成本效益的方式产生可再生电能。 在该项目中，实验方法和工艺将在所有制造步骤（吸收材料的化学合成、薄膜沉积和器件组装）过程中得到优化，并与预测特性模型相结合，以产生新的基础和探索性知识。为了实现这一目标，拟议的联盟汇集了涵盖化学、化学工程、材料科学和器件物理领域项目需求的互补能力。总体而言，该项目的结果旨在提供打破现有范式的新概念，并通过改进的基于解决方案的太阳能电池帮助未来的能源转型。
