Case Studies

DEPICT

Multi-junction CPV cells offer significantly higher photon-to-electricity conversion efficiency compared to silicon-based PV cells. However, they face challenges such as mechanical fatigue and performance degradation at high operational temperatures due to variations in the coefficients of thermal expansion among their sub-cells. 

 

Aims: The DEPICT project is dedicated to addressing the issues through efficient thermal management and active, instantaneous temperature control using thermoelectric technology. This approach is expected to result in elevated voltage output from compound semiconductor multi-junction concentrator photovoltaic (CPV) cells and substantially improved power generation performance. 

Additional goals of the project include: 

  1. Reducing the CPV device’s geometry, thereby increasing device density per wafer and reducing device costs. 
  1. Enhancing module efficiency by at least 10% compared to the closest state-of-the-art technology. 
  1. Extending the lifetime and reliability of CPV systems. 
  1. Developing cost-effective, easy-to-manufacture modules through simulation and fabrication. 

This project offers a modular and scalable market application capable of harnessing solar energy for a range of purposes, from domestic kW-scale applications to commercial MW-scale power plants. 

 

Results:  

The project partners actively participated in the 9th International Conference on Applied Energy (ICAE2017), held from 21st to 24th August 2017 in Cardiff, UK. During the conference, a presentation titled “Experimental Characterization and Multi-physics Simulation of a Triple-junction Cell in a Novel Hybrid III:V Concentrator Photovoltaic–Thermoelectric Receiver Design with Secondary Optical Element,” was delivered by Tracy Sweet. This presentation showcased the progress and innovations achieved within the DEPICT project.

Innovteg

The primary objective of the INNOVTEG project is to design and fabricate nano-structured thermoelectric materials using readily available and cost-effective sulphur, while carefully controlling their structure and properties. Through this initiative, our consortium seeks to revolutionize the implementation of thermoelectric technologies in large-scale solar renewable applications across the European Union, substantially reducing the cost to just €5.20 per kilogram. 

Objectives: 

  • Develop an extremely cost-efficient thermoelectric system suitable for integration into buildings, capable of generating an output of 30 watts per square meter and achieving a power generation cost of €533 per kilowatt peak (kWp). 
  • Foster €200 million in business growth for participating SMEs within a 5-year timeframe, leading to the creation of more than 171 jobs. 
  • Mitigate carbon dioxide (CO2) emissions by 208,000 tonnes annually during the 5-year post-project period. 

Results:

The INNOVTEG project successfully concluded with all partners participating in a final review meeting in Brussels on Tuesday, 21st October 2014. 

The European Commission commended the project, particularly highlighting the achievements in materials research, exceptional collaboration among partners, and the benefits accruing to each partner through their involvement. In terms of dissemination, the project contributed 5 papers to peer-reviewed journals, delivered 17 presentations, and presented 6 posters, one of which received the Best Poster Award. Furthermore, 4 additional papers are currently in preparation. 

The project yielded significant advancements in the performance of thermoelectric materials based on sulphur and established scalable commercial production of these materials. The project’s prototype underwent testing, and both technological and economic validations were conducted. There is potential for a follow-up project to further investigate materials and system design.
