The UN General Assembly designated 2015 as the International Year of Light. A global initiative to highlight the importance of light and lighting technologies to societal development.
It provides an opportunity to inspire, educate, and connect people on a global scale. It is anticipated that the International Year of Light will inspire people to think of new ideas, new solutions and new products for the future.
Which brings me rather neatly to a solar project that caught my eye recently.
Richard Lunt, an assistant professor from the Department of Chemical Engineering and Materials Science at Michigan State University, US, and his team have developed the world’s first fully transparent solar cell.

In theory, there’s enough light from the sun to provide all of the world’s energy needs. Clean, limitless and renewable it is a very attractive proposition.
Of course, it is not as simple as that. It doesn’t work at night and seasonality, atmospheric conditions and variable climate conditions (mostly clouds) mean it is less viable in some parts of the world.
There are other practical challenges too. Solar farms need to cover large surface areas to be commercially viable. This demand for space is also reflected for home-based solar power generation. Large solar panels are dotted on house roofs and buildings – not pretty and certainly not integrated into house design the way architects would prefer.
