Warum berichtet keiner?
Lade dir die news von 30.05.15 ( pdf Data ) runter, "dollarhunter": ). Darüber wurde in der Konferenz gesprochen und unsere Fragen wurden beantwortet .
Gibt es eine Zusammenfassung der Fragen und Antworten?
Was habt ihr für einen Eindruck, nach der Webkonferenz?
Nach der Konferenz habe ich ... ( kann man noch nicht sagen, du musst auf die Narichten aus der Türkei( Mersin) warten und ob noch mehr Investoren einsteigen ). ABWARTEN !!!!!
Oder wie findet ihr das ?

Perovskite-based mesoscopic and other hybrid solar cells have attracted enormous attention from academic and industrial researchers due to their high power conversion efficiency, low cost, and high performance under diffuse and non-ideal light conditions. However, despite these promising aspects, there are still a number of challenges which need to be resolved, such as process scale-up, in order to achieve commercial viability of perovskite solar cells.
Most academic laboratory cells use ALD, spray pyrolysis, spin coating or vacuum evaporation as the deposition techniques, which would be cumbersome or expensive at the industrial level. Dyesol has developed a series of scalable processes and techniques for scale-up of perovskite solar cells, including screen printing compact TiO2 blocking layers, screen printing meso-porous TiO2 scaffold films (~350 nm), slot die deposition of methylammonium lead iodide and slot die deposition of hole transport material. All these techniques gave uniform and consistent devices with promising performance. Scale-up to larger area modules will be discussed and performance data presented.
Dyesol investigated the factors that influence the stability of standard perovskite solar cells and carbon/perovskite solar cells, including: storage environment, temperature, light soaking spectrum, and encapsulation. Preliminary results will be presented and discussed in terms of degradation mechanisms.

Abstract
Lack of proven stability has become a major obstacle on the path of metal halide perovskite solar cells (PSCs), in particular methylammonium lead triiodide (MAPbI3), towards commercial viability. This correlates with the intrinsic affinity of MAPbI3 towards moisture and ambient air in particular, leading to its degradation in ambient conditions. We performed extensive stability tests to prove the durability of hole-conductor-free PSCs based on a triple-layer architecture employing carbon as a back contact, including outdoor tests in the hot desert climate and indoor long-term light soaking as well as heat exposure during 3 months at 80–85 °C. These results show no evidence for device degradation under the test conditions, confirming that the triple-layer device architecture provides a promising path towards realizing efficient and stable perovskite photovoltaics.

Market Release: Perovskite Stability Demonstrated Dyesol Ltd: Global Leaders in Dye Solar Cell Technology Page 1 of 2 MEDIA RELEASE DYESOL LTD | ASX: DYE | FWB: D5I Perovskite Stability Demonstrated Queanbeyan, 11 May 2015 – Dyesol Limited (ASX: DYE) is pleased to report that a research team headed by Professor Michael Grätzel has achieved 1000 hours of stability under light soaking and more than 2000 hours under temperatures of 80 ºC – 85 ºC. Further, the team has demonstrated outdoor durability of perovskite solar cells in real-world conditions. Professor Michael Grätzel is chairman of Dyesol’s Technology Advisory Board. In the scientific publication in the journal Energy Technology, in an article titled, “Outdoor Performance and Stability under Elevated Temperatures and Long-Term Light Soaking of Triple-Layer Mesoporous Perovskite Photovoltaics”, a team researching at the Center of Nanotechnology, King Abdulaziz University in Jeddah, Saudi Arabia, reported no material loss of power conversion efficiency (PCE) after imposing three critical stability tests. These are tests derived from international standards such as IEC 61646 where cells are subjected to a constant elevated temperature, light soaking, or real-world testing. Outdoor testing, as in these experiments, where very harsh conditions are encountered in the Saudi Arabian desert, is considered to be technologically robust. Stability is critical in establishing the suitability of a technology for warrantable long-life PV products. The team used a cell architecture which matches one of the systems being developed by Dyesol for commercialisation evaluation. Importantly, this architecture eliminates the use of expensive back contact conductors and also eliminates the use of a conventional organic hole-transport-material, such as spiro- OMeTAD. In addition to perovskite, the active materials are TiO 2 and ZrO 2 . Dyesol is working with Cristal in further development of these materials. Dyesol believes the technology applied in these experimental conditions is protected by patents that Dyesol enjoys access to by virtue of its licence conditions with the École Polytechnique Fédérale de Lausanne (EPFL). No competitive technology in the field of perovskites has yet to demonstrate such promising stability results. Dyesol has a commercialisation model focussed on the exploitation of solid-state DSC or Perovskite Solar Cells (PSC). Its principal substrates of choice are glass and steel for building-applied (BAPV) and building-integrated (BIPV) photovoltaic applications. Dyesol has established commercial collaborations in the UK and Turkey, and expects to announce further collaborations in key markets during 2015.
Ein erster Schritt --- aber bis selbst zum Prototyp sind noch viele Schritte zu gehen
Und schade auch, dass das alles im EPFl stattfindet und man dazu noch auf einen Beitrag zu einer arabischen Uni verweist. Ich dachte Dyesol hat 50 Mitarbeiter, die auch mal was veröffentlichen würden über ihre eigenen Erfolge.
Und der Test ist zwar ganz nett und auch wichtig, doch sicherlich wieder mit Fingernagel großen Chips durchgeführt (Darüber fehlen leider immer Angaben!). Ich würde diese Test zumindest einmal mit einer Fläche durchgeführt sehen, die man auch als Solarmodul - ohne Brille - erkennt.
Und zudem ist der Test nur ein Test von vielen die erfolgreich durchgeführt werden müssen, damit man Solarmodule für den Outdoor-Bereich mit einer Haltbarkeit und Stabilität von bis zu 25 Jahren ohne größeren Effizienzverluste am Markt positionieren kann.

Das dauert noch --- und selbst 2018 ist ein enger Terminplan dafür. Und der Aktienkurs zeigt es auch: Die frühere Euphorie bei derartigen Ankündigungen ist verflogen.
Abwarten und mal schaun wer der Glaspartner ist/wird --- denn die TKB-Bank hat einen langen Atm und wartet auch noch lange bis zu einer Entscheidung! Dazu siehe:
Auszug aus dem LOI mit der TKB-Bank
The pre-conditions to forming a binding [/b]funding agreement include the establishment of a 50/50 joint stock company (JSC) with Nesli DSC, [b]satisfactory complition of the US$ 1.9 million prototyp facility in Mersin and submission of a detailed business plan to TKB.Und damit fällt die Entscheidung wohl frühestens Ende 2016 --- bis dahin kann noch viel geschehen --- aber Nesli wird Dyesol schon im Nacken sitze.
Und warum erst Ende 2016?
Dazu hat Dyesol ja im letzten Quartalsbericht genauere Angaben gemacht. Der prototyp soll in 12 - 18 Monaten kommen. Aus der Erfahrung heruas sind dann eher 18 Monate anzunehmen, also Ende 2016.
Ich denke es wird wohl erst 2020 was wirklich funktionierendes geben wird. :(
