1Sun Ltd. is aimed at the successful transfer of extensive R&D efforts in identifying innovative Renewable Energy sources, to their large scale industrial production. Founded by Dr. Sumeet Kumar, Engineer and PhD, 1SUN aspires to partner with top Research institutes and industries particularly in Italy, India and various other Solar prominent regions of the World.
To furnish its innovative and cost effective solutions, 1SUN plans to deploy its patent-filed technology, principally towards developing novel and cost effective, Quasi1D panels, through the incorporation of the proprietary, hybrid nanomaterials, which already have proven records (laboratory scale) showing the potential to enhance Photovoltaic performance of the current PV panels by > 10 %, when applied merely as Light Energy Down converter, via. a product currently sold (on demand at c.a. 50 euro/kWp of Si-PV to be covered*);
The pure nanomaterials (production cost of c.a. 1.08 euro/gm) are also available for independent selling OR to be inserted at the EVA (existing PV encapsulate) level, while the recipe can be given under Licensing , under the name Hybrid Nano Materials (hNMs);
The hNMs incorporated into UV transparent PLEXI renders a product coined by us as: Wavelength Conversion Film (WCF) which comprises of a commercially available UV transparent polymeric matrix, encapsulating inside the UV to Vis. conversion Hybrid Nanomaterials (hNMs).
These hNMs, are proven to sustain a temperature of 350º C, under pure oxygen environment, and are found to have a constant sharp (with a small FWHM) SINGLE Wavelength, RED (614 nm) laser like emission, on the advent of excitations from 290-370 nm (UV excitation**). The hNMs are transparent to Visible light, and having the lanthanide element, europium, in doped quantity, as the core Continuous Wave; Single Wavelength-RED emitter, via. hopping of UV energy through TWO organic molecules (intercalated/Stabilized inside the layered structure of the nanocomposite), having Energy transfer rates in the order of nanoseconds (ns), emits the PROLONGED (Due to Decay lifetime of the RED/Eu3+ emission of the order of microseconds), RED emission with a continuous PUMPING (Inter State Coupling-ISC) to the europium atom, stabilized via self assembly along wih the TWO organic chelates, into the 2D layer of the Layered Double Hydroxide like hNMs.
Green cylinder = Organic intercalates/Chelating molecules. Blue 2D layers = M(II), M(III) ions, +ve charge is created onto 2D layers via. mole imbalance compensated via. organic groups. Orange pyramids = M(III) sites replaced in real time, via. Lanthanide (EUROPIUM), RED pyramids.
Towards RetroFiTTING the existing and under performing “incentivized” PV plants, 1SUN is deploying its first production plant at PILOT scale, covering a maximum of 200 kWp NEW Modules, intervening at external film level and EVA level and installing them as ‘mixed’ Strings, doped with the hNMS/WCF technology along with certifications from recognized institutes like
Fraunhofer ISE and TUV from Germany, especially of the EVA level interventions, which requires a Re-Certification of the whole module.
As a part of its Industrialization and hence as an expansion process, 1SUN has now access to the Founders’ Italian Patent, Granted on 19-06-2015 and lately conferred by Dr. Kumar into 1SUN via Capital raise, which is being used as ‘entry’ criteria into various markets of interest to 1SUN, having extended the Italian Patent in TEN countries since 01-09-2015, benefiting with an excellent 100% POSITIVE European Patent Office (EPO) International Search Report, on its International filing (25-02-2014).
Dr. Kumar’s Patent
entitled “HYBRID COMPOSITE NANOMATERIALS
” is now published
with the following number: WO14/132183
The innovative StartUp also offers expert consultancy to its clients, thereby helping them meet their goals and maximize the gain from the hNMs derived WCF over existing PV panels, while extending it, on successful prototyping completion of Quasi1D panels, through intelligent Energy management systems, including micro inverters, circuited while weaving of Quasi1D panels.
*With the hNMs dispersed at the rate of 10% wt/wt into the UV transparent PLEXI polymer; Price estimated including c.a. 2 euro/m2 of PLEXI for obtaining a c.a. 0.05 mm/50 micron thickness of final WCF, with hNMs production cost at 1.08 euro/gm.
**While UNDER PROTOTYPING, is the planned rendering of the hNMs (thanks to their versatility and ease of preparation), such that they are capable to convert also the IR into Visible along with having an Anti Reflection phase, generated insitu, during the ONE-POT, hence cheaper and industrially viable, hydrothermal (least environmental polluting) synthesis.
