Spanish tech company Oxolutia has developed Solar Oxides, flexible photovoltaic solar cells that can be manufactured by 3D printing. Using conductive oxides, a non-toxic, stable, and low-cost material found abundantly in nature, the cells open up exciting new opportunities for generating low-cost solar energy.

The Solar Oxides team

The photovoltaic solar cells are installed on panels to absorb solar radiation for solar thermal plants. More traditional methods include using monocrystalline silicon, however given the low cost of the raw materials and 3D printing production process, Solar Oxides offer a much more competitive advantage. This technological breakthrough would be a boon to the energy sector, where there is a growing demand for environmentally friendly, stable, secure and more energy efficient systems, especially as we continue to deplete earth’s natural resources and increase carbon emissions. The affordable, 3D printing-enabled solar technology could also be used in other industries, such as transportation, medicine and tele-communications.

Oxolutia is a technology-based spin-off of the Institute of Materials Science of Barcelona (ICMAB) that aims to conduct research and bring to market processes and materials in the field of applied superconductivity and nanotechnology. In order to create the flexible solar cells, the engineering team utilized 3D inkjet printing, which allows drop-wise deposition of liquids onto surfaces, combined with chemical solution deposition approaches for producing oxide thin films. They believe this is a technology that will open new avenues for digital fabrication, graded materials, and additive manufacturing. Having developed the pilot plant in 2013, they expect to have a workable prototype by next year.

The project has been selected by Repsol as one of nine winners of the 2015 Fundación Repsol Entrepreneurs Fund. Repsol is one of the world’s largest energy groups committed to renewable sources and preserving the environment, and their Fund, now in its fourth year, is aimed at entrepreneurs dedicated to improving the field of energy efficiency and energy saving with innovative technological projects.

Of the nine projects awarded grants, four were submitted by researches and entreprenurs at the Esfera UAB-CEI research cluster, including Solar Oxides. Chosen from among over 200 entries, these projects will receive a grant of up to €288,000 over a maximum of two years, and will also be allocated a team of tutors, specific training, and technical and legal advisors in order to get their technological solutions to the market as quickly as possible. To that end, they will also be granted office space in the Repsol Technology Centre in Madrid, Spain.

Would love to know how such 3D cells for photovoltaics are printed and the support material used. Are they printed in gravure, in offset, flexography, inkjet....Obviously: I would love to know the ink used..... Is there any Company researching about the pros by using the 3D technology instead of the silicon material?

Nowhere do they say the power density or efficiency of these "cheap" solar cells. If it takes an acre of land area of cheap solar cells to make the same amount of solar energy as one can get off of the roof of a house with monocrystalline PV, then the amount of structure you have to build to support the "cheap" cells is going to cause the old "expensive" monocrystalline cells to be more cost effective. Currently the cost of the "expensive" PV cells are a small part of the cost of an installed solar system - you also have to pay for a mounting system, and "balance of system" electronics to prevent your PV array from damaging itself or the equipment you want to power with it, and you have to connect to the electricity grid or a storage system for the power. Not to mention all the labor involved in designing and building all these systems, which goes up at least proportional to the area occupied by the array. So "cheap' cells that are inefficient or low power density are not necessarily the most cost effective solution.

10 years ago someone proposed printing solar cells with a ink jet printer. Do you have ink jet solar cells covering your roof? This id Bovine fecal matter
