Achieving an efficient and sustainable photovoltaic system has become a necessity to meet the growing demand for energy in many areas and contexts. However, mass production methods to manufacture efficient and stable halide perovskite solar cells in a safe and sustainable manner pose scientific and technological challenges, and laboratory-scale manufacturing methods cannot be scaled up.

The commercialisation of halide perovskites, which have revolutionised the field due to their high photoconversion performance in the laboratory, has become a priority issue involving many research groups and companies worldwide. A consortium of six research centres and four companies (HEPAFLEX), including the team from the Institute of Advanced Materials of the Universitat Jaume I in Castelló, led by Iván Mora Seró, has set out to develop flexible, high-performance perovskite solar cells that can be adapted to different contexts.

To achieve large area efficiency, HEPAFLEX will combine fast photonic annealing methods and large area perovskite thin film fabrication with green chemistry routes, redesigning the processing approach and establishing a sustainable photovoltaic technology based on manufacturing circularity, flexibility, versatility, substitution and recycling.

This high-performance approach, based on versatile and low-cost flexible substrates, is an opportunity to reduce the environmental and economic impact of cells by ensuring versatility of use in multiple applications and by enabling a flexible substitution strategy that will extend the effective lifetime of high-power rigid modules to more than 25 years, reducing the cost and carbon footprint of today's photovoltaic technology.

The development of a unique process will also enable pure non-utility scale flexible applications that maintain the highest efficiencies. These applications, which are not currently feasible, will reduce competition between different types of land use. The project will therefore ensure the safety of the technology with additives to sequester lead to prevent leakage, integrated with recycling methods to reuse the materials used in the manufacture of the modules.

The consortium partners have been carefully selected on the basis of their research and commercial activities in the development, characterisation, regeneration and exploitation of perovskite solar cells and other photovoltaic technologies. The consortium consists of CSIC, the universities of Valencia and Jaume I de Castelló (Spain), Ben-Gurion of the Negev and Bar-Ilan (Israel), Kauno Technologijos (Lithuania) and École Polytechnique Federale de Lausanne (Switzerland), as well as the companies Saule Spolka Akcyjna (Poland), Solaveni GMBH (Germany), Lomartov SL (Spain) and Rinovasol Global Services BV (Netherlands).
