Main tasks attributed in the project

Tasks of EPFL:

EPFL will be involved mainly in WP2, of which it is WP leader, WP3, WP4 and WP5. Main activities foreseen are the following:

  • Profiting from the high open circuit photo-voltage output of the PSC (Voc > 1.2 V) we aim at reaching a PCE of 6 % from 80% transparent PSC top layer alone.

  • Development of new perovskite compositions to reach 5 % PCE with near UV absorbing PSC device that produces a Voc of at least 1.8 V

  • Fabrication of high efficiency DSC devices using NIR dyes and monitoring their stability.

  • Development of new metal oxide scaffolds for PSCs and DSCs.

Development of new transparent redox electrolytes.

Profile of EPFL:

EPFL is an established world leader for dye- and perovskite-sensitized solar cells having pioneered both solar cells concepts. This is documented by high-impact publications throughout the years as well as a dedicated effort towards certifying device performances on a regular basis (which make EPFL the only European lab to certify perovskite solar cells). Based on this expertise, EPFL has an ideal profile to fulfil the above tasks:

  • EPFL demonstrated that the small and oxidation-stable Rb+ cation can be embedded into a “cation cascade” to create a perovskite material capable of achieving efficiencies up to 21.6% with a record open– circuit voltages of 1.24 V. Importantly, these materials passed the stringent endurance tests being exposed simultaneously to full sun light and 85 °C for 500 h while operating at their maximum power point. EPFL has not optimized these compounds fully

  • It is currently very challenging to increase the perovskite thickness without losing film quality. EPFL has developed expertise to handle the perovskite material including thickness variations. Already some if the highest currents are reported at EPFL at therefore it is reasonable that this can be pushed to the theoretical limit in the future.

  • Similar to the multication approach, EPFL has the expertise to screen, characterize and assess complex material group. This includes especially perovskite materials that are only varied through the metal positions. However, this knowledge can be extended towards perovskite-like materials as well where expertise is required to develop the material and to translate it towards a high throughput of devices

  • EPFL has recently developed a new method for depositing this wide band semiconductor in the form of thin films. EPFL identified the reason for its notorious instability and succeeded in solving the problem by introducing a separation layer between the CuSCN and the back contact. This led to PSCs showing a PCE over 20 % and excellent stability both under long term heat stress at 85 °C and prolonged light soaking. Since the parameter space for sample development is very large, the optimization procedures need to be supported by predictive methods which will allow to focus solar cell test series only on promising preparation formulations.

HGlass (HG) former Glass2EnergySwitzerland

Institution Description

HGlass was founded in 2011 with the vision to develop the Eco-Habitat and become a world leader in sustainable living. HGlass develops, produces and commercialises dye-sensitized solar cell (DSC) panels for generating electricity in architectural applications, i.e. building integrated photovoltaic (BIPV) aiming at the exploitation of glass facades. With its unique hermetic glass sealing technology HGlass surmounted the sealing problem, which had hampered industrialization of the technology for the past 20 years.

HGlass maintains a total staff of 54 employees at its production facilities in Villaz-St-Pierre and at its Research and Development center at EPFL Innovation Park. HGlass received the Watt d’Or 2014 Award from the Swiss Government’s department of Energy generating major interest from both the public and private sectors.

The company has an in-depth know-how of the critical issues regarding device construction and manufacturing processes for this technology. Long-time stability problems of DSC are known to arise from imperfect device/cell encapsulation methods which mostly employ sealing using polymer based adhesives (hot melt/epoxy based), plastic sheets, and/or foil encapsulation techniques. To date, these sealing techniques and materials have not proven to be durable enough to guarantee long-time stability during outdoor operation, and therefore are not suitable for HGlass’ target of BIPV market.

During the start-up phase, HGlass has developed a proprietary technology for rapid hermetic sealing of DSC modules, which is suitable for mass production. This unique glass processing technology provides the most effective barrier against humidity and oxygen, alleviating any concern for module durability. Glass sealing technology and large module sizes enable the company to meet the market demand for large units in high surface area architectural projects. Currently, HGlass is completing a series of tests for IEC 61646 certification. Securing a supply chain to reduce the cost of raw materials, a pipeline of innovative developments has been another major part of activities since the inception of HGlass. Specifically, the most expensive raw materials (dye, electrolyte, and TiO2 nano-particles) are produced in-house, delivered by sister companies or produced by HGlass


Main tasks attributed in the project

Tasks of HGlass:

HGlass will be involved mainly in up scaling of DSC modules, WP6, of which it is WP leader. Main activities foreseen are the following:

  • Fabrication of a large surface single cell, 10 x 150 mm, using NIR dyes and transparent redox electrolytes developed by WP3.
  • Fabrication of 150 x 150 mm high efficiency DSC module using the same NIR dyes and transparent redox electrolytes.
  • Fabrication of large area modules, 745 x 745 mm, using NIR dyes and transparent redox electrolyte developed by WP3.
  • HGlass will monitor the outdoor and indoor electrical performance and stability of samples by proposing appropriate electrical connection and BOS (Balance of System)

HGlass USP’s and industrial strengths are:

  • Unique and proprietary glass encapsulation: providing the only sure way to avoid both unwanted water ingress into the cell and leakage of the liquid electrolyte components from the cell. HGlass is the only company with this know-how.
  • Large size modules for façade application: HGlass manufactures modules of up to 800 x 1000 mm size. This is critically important for the BIPV market – from both practical and aesthetic standpoints. In Q4 of 2018 an even larger size product measuring 1000 x 1000 mm will be launched. This will further increase HGlass’ lead over potential competitors.
  • HGlass modules combine high transparency with high efficiency: With 4% solar to electric power conversion efficiency (PCE), on total area, and 35% transparency, HGlass produces DSC modules with the highest performance and transparency.
  • HGlass’ industrial production line is fully operational: . It is now running at its peak capacity of 20,000 modules per year in 3 shifts. 
HGlass see through panels have distinct advantages over conventional silicon-based solar cells in Building Integrated Photovoltaic (BIPV) applications. Importantly, HGlass panels offer a large flexibility in tailoring their light-harvesting spectrum by judicious selection of the sensitizer as well as the film thickness. Importantly HGlass panels come naturally as a bifacial photovoltaic, capturing light from the front and backside. These features render the DSC particularly efficient in harvesting in ambient light, (e.g. albedo, diffuse sunlight, cloudy conditions, and at dusk and dawn, where it outperforms all PV competitors including GaAs. Also, DSCs do not exhibit the 20% decline in the PCE with increasing temperature from 25°C to 65°C (normal operating temperature) which is typical for silicon. Finally, the angle of incidence of incoming light has a low impact on its photovoltaic performance. The entire building envelope (NESW façade orientations, roof) as well as indoor space can thus be dedicated to power generation. The HGlass technology features transparent glass elements that can be produced in a palette of colors and shapes, opening new and esthetically attractive design possibilities for architects. Thus, DSCs open up new markets that are not accessible to conventional photovoltaic. These highly attractive products come as an addition to state-of-the-art photovoltaic power generation systems with added value in architectural design and a proven stable efficient power production even under ambient lower intensity light.
