Project Summary
Elevator Pitch

Concise Summary: Help us pitch this solution! Provide an explanation within 3-4 short sentences.

The applicant is seeking to join forces with the experimental group of Dr. Maria Vasilopoulou at Demokritos National Lab, Athens, Greece. The aim is to fabricate efficient optoelectronic devices, such as organic solar cells, supported by new theoretical knowledge via materials modeling.

WHAT IF - Inspiration: Write one sentence that describes a way that your project dares to ask, "WHAT IF?"

What if efficient organic solar cell devices could produce free electricity as a direct consequence of the bright Athenian sun and joined scientific efforts?
About Project

Problem: What problem is this project trying to address?

The applicant has already established a collaboration with the group of Dr. Maria Vasilopoulou at Demokritos National Lab, Athens, Greece, but computational resources to model organic optoelectronics devices are limited. Although Demokritos owns experimental facilities to pursue quality research on the above field, a dedicated computer cluster that would boost efforts further, via modelling, is missing.

Solution: What is the proposed solution? Please be specific!

A computer cluster of 256 processors built in Athens would initially be sufficient to solve the problem. The applicant could use these facilities to model optoelectronics devices, such as organic solar cells, to aid the experimental efforts performed at Demokritos National Lab. The applicant has broad experience in materials modeling, in terms of optoelectronic devices, which is proved by his ability to publish scientific articles in high-impact journals like Science, Advanced Functional Materials and Chemical Science.
Impact: How does it Work

Example: Walk us through a specific example(s) of how this solution makes a difference; include its primary activities.

The applicant's methodology is validated via ultraviolet photoelectron spectroscopy as well as X-ray photoelectron spectroscopy on metal and metal-oxide surfaces. The applicant’s work is published in high-impact journals such as Science and Advanced Functional Materials [T. Papadopoulos et al., Science 336, 327 (2012) and T. Papadopoulos et al., Adv. Funct. Mater. 23, 6091 (2013)]. The computational approach that could be implemented on Hipparchus, would make use of a modern modeling technique, which consists of a combination of Density Functional Theory, Monte Carlo and Poisson equation. Modeling at this level would help us evaluate and eventually fine-tune materials properties in order to build efficient optoelectronics devices.

Impact: What is the impact of the work to date? Also describe the projected future impact for the coming years.

The applicant's research aims to generate fundamental knowledge as well as provide the theoretical background to control and fine-tune electronic and optical properties of materials. The applicant expects that this will have positive impact on the competitiveness within Greek academia as new scientific knowledge could be widely shared. The proposed Hipparchus computer cluster would further enhance the ability to publish high-impact scientific articles. This would increase the professional competence of both the applicant and Demokritos National Lab (DNL) improving their overall competitiveness and productivity. Long-term collaboration between the applicant and DNL, via the use of Hipparchus, would provide solid foundation for further collaborative research efforts in partnership with other members of the Greek academic community as well as within the wider industrial sector in Greece.

Spread Strategies: Moving forward, what are the main strategies for scaling impact?

The increasing need for electrical power, depleting fossil fuel reserves and global warming is the driving force behind governments and consumers alike, to move towards solar cell applications. As silicon prices are continuously increasing, the market for organic solar cells is expected to grow steadily. Their lightweight, flexible, ultra-thin and organic nature can prove to be beneficial for a sustainable future. Such trend is expected to boost the organic solar cell market growth in the next years as organic photovoltaics promise integration into a big range of everyday life applications.
Sustainability

Financial Sustainability Plan: What is this solution’s plan to ensure financial sustainability?

The University of Bolton and Demokritos National Lab provide the annual salaries of the applicant and team in order to conduct scientific research. Demokritos National Lab would also be in charge of maintenance costs of the proposed Hipparchus computer cluster built on its premises.

Marketplace: Who else is addressing the problem outlined here? How does the proposed project differ from these approaches?

High-class research is always conducted via joint efforts between experimental and theoretical/computational groups. For example, research funding bodies in the USA and EU always require successful projects to include collaborative efforts by research groups of both experimental and theoretical expertise with links to industry. Quality research cannot be conducted if scientific knowledge and understanding is not enhanced via modelling. It is hence imperative that a National Lab like Demokritos has it's own computer cluster dedicated to materials modeling.
Team

Founding Story

While the applicant was a researcher at Georgia Institute of Technology, Atlanta, USA, he came across, in the literature, the research activities of the group of Dr. Maria Vasilopoulou. He immediately realized that she was conducting impressive research in the field of organic optoelectronics without though much theoretical/computational input. He therefore contacted Dr. Vasilopoulou with a proposal to join efforts towards their common research interests, to which he received very positive response! This is how a joint experimental and theoretical collaboration between Greece and the UK was born.

Team

Dr. Maria Vasilopoulou is a senior researcher at Demokritos National Lab, Athens, Greece. Her main research interests are the fabrication and characterization of organic electronics devices, especially of organic solar cells and organic light emitting diodes for displays and solid state lighting. She is an author of many scientific articles published in high-impact journals such as the Journal of the American Chemical Society.
