The improvement in efficiency is based on the optimisation of the buffer layer with respect to InxSy bandgap, band matching, and in particular transmission in a short wavelength range. In addition, the transmittance and the sheet resistance of the sputtered ZnO:Al front contact was optimized and the dead area between the series-connected cells was reduced by the use of picosecond laser process
POET Technologies closes $5 million private placement
The proceeds will fund the company’s internal and third party development efforts necessary to complete the milestones required to enable the monetisation of the POET Technology
POET Technologies Inc. has announced the closing of its non-brokered private placement financing of 7,692,307 Units at a price of Canadian $0.65 per unit for proceeds of Canadian $5 million.
Each unit consists of one common share and one common share purchase warrant. Each warrant allows the holder to acquire one additional common share of POET for a period of two years at an exercise price of Canadian $1.00 per share.
All of the securities issued pursuant to the private placement are subject to a hold period which expires on June 13th, 2014. No commission was payable with respect to this financing.
The proceeds will be used to fund the company’s internal and third party development efforts necessary to complete the milestones required to enable the monetisation of the POET Technology.
The proceeds will also be used to cover general and administrative expenses, and working capital. The Canadian $5 million dollar placement strengthens POET’s balance sheet to enable it to continue implementing its monetisation strategy to increase shareholder value.
Following the closing of the private placement there are currently 142,800,040 shares issued and outstanding.
UK universities awarded £2 million for solar cell research
The project aims to replace gallium, indium, cadmium and tellurium used in the manufacture of photovoltaic solar cells, while also implementing processes compatible with large-scale manufacturing
A University of Bristol-led research project which aims to develop new active materials for photovoltaic solar cells based on abundant and low cost elements has been awarded £2 million funding by the Engineering and Physical Sciences Research Council (EPSRC).
The study ‘Photovoltaic Technology based on Earth Abundant Materials (PVTEAM)’, led by David Fermin, a professor in Bristol’s School of Chemistry, is one of four research projects to be awarded a total of £10.3 million by the EPSRC.
Each project aims to find safer, more sustainable alternatives to many of the raw materials used by manufacturing industries.
The Bristol-led research aims to replace key elements - such as gallium, indium, cadmium and tellurium - used in the manufacture of photovoltaic solar cells, while also implementing processes compatible with large-scale manufacturing. As these elements have low abundance, high costs and high toxicity, finding alternatives to them represents an extraordinary opportunity.
Fermin saiys, “The aim of this programme is to lay the foundations of sustainable thin-film photovoltaic technology based on Earth-abundant materials and scalable manufacturing
processes.This will be achieved by developing processes and production technologies for materials and material systems to a level they can be taken up by manufacturing industries.
“PVTEAM will specify a carefully selected range of chemical compounds (chalcogenides and oxides) as substitutes to proven commercial materials. Using a multi-level screening approach, we will incorporate the
