New Energy Technologies, Inc., developer of see-through solar cells for generating electricity on glass windows, recently announced that researchers have successfully achieved faster fabrication time, improved transparency, and a two-fold increase in power conversion efficiency. Researchers achieved the advances by way of a novel, patent-pending breakthrough, which enables fabrication of large-scale mini-module SolarWindow devices, important to commercial deployment of the world's first-of-its-kind glass window capable of generating electricity.

Generating electricity on glass windows is possible when New Energy researchers spray ultra-small, see-through solar cells on to glass surfaces. These novel spray-on techniques have been pioneered, advanced, and unveiled in operating prototypes by scientists who initiated early research efforts with New Energy Technologies under a Sponsored Research Agreement at the University of South Florida (USF). The Company's SolarWindow technology has since progressed significantly beyond early research, and is now in advanced product development.

Meanwhile, these announcement are the outcome of spray-related improvements achieved during the completion phase of New Energy's early Sponsored Research at USF, led by Dr. Xiaomei Jiang. Researchers report that these latest spray-on techniques have successfully:

· Boosted power conversion efficiency of each individual cell by two-fold compared to previous fabrication methods, leading to overall power output improvement of SolarWindow;

· Reduced fabrication time from several days down to only a few hours, or 1/6th of the time normally required;

· Improved the transparency or visual light transmission of SolarWindow modules, creating a widow tint effect; and

· Achieved an aesthetically attractive, uniform coating on to glass important to consumer appeal.

Specifically, these performance improvements result from spray advancements which control fabrication of various layers of coatings on glass; collectively, these layers make up the architecture of SolarWindow modules. Among other functions, the various layers allow the glass to absorb the sun's energy, generate electricity, and direct the electricity for collection and use.

Researchers are hopeful that this breakthrough in mini-module spray-on device fabrication leads to improved spray-on techniques for large-scale devices, a precursor to the Company's product for commercial launch.

This latest breakthrough is an exciting testament to our ongoing efforts as we continuously work to improve the quality and performance of our SolarWindow mini-modules, explained Mr. John A. Conklin, President and CEO of New Energy Technologies, Inc. Moving forward, we remain devoutly focused on producing large surface area prototypes which are compatible with high-speed production methods, important to commercialization of SolarWindow.

Currently under development for eventual commercial deployment in the estimated 85 million commercial buildings and homes in America, SolarWindow technology is the subject of fourteen (14) patent filings and is the world's first-of-its-kind technology capable of generating electricity on see-through glass windows.

SolarWindow is a building integrated photovoltaic (BIPV) technology. BIPV products are expected to achieve compound annualized growth of 41%-plus through 2016, according to Pike Research.

About New Energy Technologies, Inc.

New Energy Technologies, Inc., together with its wholly owned subsidiaries, is a developer of next generation alternative and renewable energy technologies. Among the Company's technologies under development are:

MotionPower roadway systems for generating electricity by capturing the kinetic energy produced by moving vehicles a patent-pending technology, the subject of 45 US and International patent applications. An estimated 250 million registered vehicles drive more than six billion miles on America's roadways, every day; and

SolarWindow technologies, which enable see-through windows to generate electricity by spraying their glass surfaces with New Energy's electricity-generating coatings the subject of 14 patent applications. These solar coatings are less than 1/10th the thickness of thin films and make use of the world's smallest functional solar cells, shown to successfully produce electricity in a published peer-reviewed study in the Journal of Renewable and Sustainable Energy of the American Institute of Physics.

Through established relationships with universities, research institutions, and commercial partners, we strive to identify technologies and business opportunities on the leading edge of renewable energy innovation. Unique to our business model is the use of established research infrastructure owned by the various institutions we deal with, saving us significant capital which would otherwise be required for such costs as land and building acquisition, equipment and capital equipment purchases, and other start-up expenses. As a result, we are able to benefit from leading edge research while employing significantly less capital than conventional organizations.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
