TEL unveils DeltaStream tidal device

First published on the Cleantech Investor website, 7 August 2014

Tidal Energy Ltd (TEL) has unveiled a tidal energy generator at Pembroke Port in Wales. The 400kW DeltaStream demonstration device will be installed in Ramsey Sound, Pembrokeshire and will be connected to the grid. The device was unveiled by The First Minister of Wales, the Rt. Hon. Carwyn Jones, who commented that:

“This is a landmark project for Wales, which will not only help us to meet our sustainable energy ambitions, but will also provide significant opportunities for local people and businesses.”

The China CleanTech Index recorded a 1.4% loss in July 2014 but still outperformed all but one of its four benchmarks for the month. The best performing sub-indices for the month were the China Hydro Index with a 6.7% gain and the China Efficiency Index with a 1.0% gain. The two weakest sub-indices through July were the China Storage Index which recorded a loss of 7.5% and the China Solar Index recording a loss of 7.3%.


Perovskite solar cell breakthrough at University of Sheffield

First published on the Cleantech Investor website, August 2014

The University of Sheffield has announced that scientists from the Departments of Physics and Astronomy and Chemical and Biological Engineering are the first to fabricate perovskite solar cells using a spray-painting process – a discovery that could help cut the cost of solar power generation.

Efficient organometal halide perovskite based photovoltaics were first demonstrated in 2012. Perovskite combines high efficiency with low materials costs and combined with spray-painting - which has previously been used to produce solar cells using organic semiconductors - a process has been developed to use peroskites in high volume manufacturing.

The Perovskite spray-painting techniques waste very little of the perovskite material and can be scaled to high volume manufacturing – similar to applying paint to cars and graphic printing. According to lead researcher, Professor David Lidzey:

“This class of material offers the potential to combine the high performance of mature solar cell technologies with the low embedded energy costs of production of organic photovoltaics.”

BYD enters Brazil

BYD Company Ltd is set to become the first Chinese battery manufacturer to open a plant in Brazil, in a clear indication that the country (historically a leader in ethanol biofuel) aims to adopt electric vehicles. BYD signed a contract in the presence of both China's President Xi Jinping and Brazil's President Dilma Rousseff, during the BRIC Summit in Brasilia. According to Apex-Brasil President, Mr. Mauricio Borges, Brazil is at a critical point in its history when it must adopt renewable energy technologies (Apex-Brasil, the Brazilian Trade and Investment Promotion Agency, structured the deal with BYD).


Strategic investor GAF joins KPCB in $31m Series D funding for Solexel

First published on the Cleantech Investor website, July 2014

California based Solexel has raised US$31 million in equity for the commercialisation of its thin‐crystalline silicon solar modules. Investors included GAF, the largest roofing materials manufacturer in North America, alongside existing shareholders, who include Kleiner Perkins Caufield & Byers, Technology Partners, DAG Ventures, Northgate Capital, GSV Capital Corp, Gentry Venture Partners and Jasper Ridge Partners. Solexel has also received investment from Sunpower. Solexel was incorporated in 2007, and has a fully operational pilot fab in Milpitas, California. It is building a 1 MW capacity manufacturing plant in Malaysia.

Solexel developed a BIPV solar roofing shingle with Owens-Corning, with support from a $13m US DoE grant. Its PV modules for the residential, commercial and utility-scale market segments are based on its ultra-thin silicon solar cell technology, which offers the performance, quality and reliability of the industry’s best-performing cells, at significantly lower cost.
