Innovative Solutions for Sustainability provides technology solutions to support a sustainable world. The document discusses Abengoa's solar power technologies and the requirements for metal photovoltaic substrates. It also summarizes a current steel photovoltaic project that is developing methods to functionalize structural steels for use as substrates in photovoltaic technologies for building integrated applications. The project involves selecting steels, developing intermediate layers through vacuum, chemical and hybrid approaches, and testing the feasibility of integrating different photovoltaic technologies at both the laboratory and pilot plant scales.
