VALAIS PEROVSKITE

Enoil Bioenergies SA owns 40% of VPS – Valais Perovskite Solar SA.
VPS – Valais Perovskite Solar is a company based in Switzerland with the focus on Molecular Engineering of Functional Materials for Photovoltaic and Light-emitting applications. Prof. Md. K. Nazeeruddin owns 50% of VPS – Valais Perovskite Solar SA and is Head of Research and Development.


OUR VISION

The target of the company is to bring an abundant and renewable source of energy using low-cost solar cells to all over the world.

The goal of the group is to engineer at molecular level novel panchromatic sensitizers and functionalized hole-transporting materials to achieve power conversion efficiency (PCE) surpassing 23%. Because many chemical combinations result in a perovskite crystal structure, and each of them has different optical properties, choosing the chemistry of a cell also means choosing what part of the spectrum it absorbs, this could push efficiency levels in the future up to around 36%. It may be possible to manufacture also a panel that is 30% efficient using standard solar cells in combination with perovskites.

One of the most exciting parts of perovskites is their high efficiencies. Based on lab calculations, perovskite solar cells are capable of beating the capabilities of traditional mono- or poly-crystalline silicon cells. Another advantage of perovskite solar cells is that they are based on a human-made material that can be produced at a low cost.Perovskite solar cells are a new type of solar cell made from a class of man-made materials called perovskites. Perovskites are a different material than the silicon wafers that make up traditional solar panels. They have a crystallographic structure that makes them highly effective at converting photons of light from the sun into usable electricity. Perovskite solar cells represent a high-efficiency, low-cost solar technology, and shall be the future replacement for traditional silicon solar panels.

POTENTIAL

One of the most exciting parts of perovskites is their high efficiencies. Based on lab calculations, perovskite solar cells are capable of beating the capabilities of traditional mono- or poly-crystalline silicon cells. Another advantage of perovskite solar cells is that they are based on a human-made material that can be produced at a low cost.

Presently, over 85% of the World’s energy requirements are satisfied by fossil fuels with devastating consequences on the environment and society.1 The energy demand is predicted to increase by almost 30% during the next 20 years due largely to population growth and, consequently, solar energy is considered as the ultimate source of clean, secure and renewable electricity. The world global installed photovoltaic (PV) capacity will likely reach well over 1000 GW by 2030 and could reach up to 5000 GW by 2050. At this moment, solar energy will be one of the major electricity sources worldwide, with the lowest costs and environmental impact, while contributing to mitigating CO2 gas emissions. Solar energy is indeed recognized as the fastest growing technology by the World economic forum (press, October 2017), and appointed as the future solution for a carbon-free economy given the limited finite sources of planetary energy reserves (see Figure 1). The use of silicon-based solar systems is widespread accounting for over 90% of the installed PV. However, their manufacturing costs remain high due to in part technologically intensive fabrication of silicon wafer. New PV technologies with higher potential performances at a lower manufacturing and materials cost will lead to a paradigm shift in energy generation. In this context, the new technology based on Perovskite solar cells (PSCs) has emerged in the last few years and nowadays considered one of the most excited PV technology of our time. PSCs are leading a real revolution in power generation, standing over the main technologies on the market, reaching power conversion efficiency (PCE) surpassing 23%.2 In addition to high efficiency, their low-temperature solution deposition methods compatible with printing are the great advantage over existing technologies making the PSCs cost effective with the levelled cost of electricity below the mainstream silicon photovoltaics.


AWARD

Valais Perovskite Solar Energy and Enoil Bioeneriges SA won in 2018 the gold medal in the International Exhibition of Inventions in Geneva, Switzerland.


F.A.Q.


R&D DIRECTOR

Prof. Md. K. Nazeeruddin received M.Sc. and Ph. D. in inorganic chemistry from Osmania University, Hyderabad, India. He joined as a Lecturer in Deccan College of Engineering and Technology, Osmania University in 1986, and subsequently, moved to Central Salt and Marine Chemicals Research Institute, Bhavnagar, as a Research Associate. After one year postdoctoral stay with Prof. Graetzel at Swiss federal institute of technology Lausanne (EPFL), he joined the same institute as a Senior Scientist.
In 2014, EPFL awarded him the title of Professor. His current research at EPFL focuses on Dye Sensitized Solar Cells, Perovskite Solar Cells, CO2 reduction, Hydrogen production, and Light-emitting diodes. He has published more than 509 peer-reviewed papers, ten book chapters, and he is inventor/co-inventor of over 50 patents. The high impact of his work has been recognized by invitations to speak at over 130 international conferences.
