Metallic nanoparticles can direct light better into the solar cell and prevent light from escaping. In conventional 'thick-film' solar cells, the nanoparticles would have little effect because all the light is absorbed by the film due to its thickness. For thin films, however, the nanoparticles can make a big difference.

Egbe has achieved an efficiency of four percent and is trying to find out how to improve the efficiency in general. Not only for his system, but also for other systems researchers are working on. "The efficiency of organic solar cells has already reached eight percent and commercial products are on the market," he said.

The size, shape and organization of light-harvesting complexes such as chlorosomes are critical factors in electron transfer to semiconductor electrodes in solar devices. Understanding how chlorosomes function in nature could help scientists mimic the chlorosome's efficiency to create robust biohybrid or bio-inspired solar cells.

Solaroad is a road that also works as a solar panel. The combination of these two functions is special, and makes it possible within the space we still got to road use even solar energy to capture and converting it into electrical energy, which then can be used for street lighting, traffic systems, but also households.

The Solar Impulse is the brain child of Bertrand Piccard, a Swiss adventurer and environmentalist, who launched the project back in 2003 with the aim of promoting the use of renewable energy sources. Now, in 2009, he is closing in on that dream. His plane has a 200-foot wingspan which is lined with 12,000 photovoltaic solar cells that will draw energy from the sun to power its four engines.

In this initial project, it will be important to demonstrate the possibility of manufacturing high-purity silicon from desert sand and constructing a high-temperature superconducting, long-distance, DC power supply system. The aim is to achieve a solar plant with annual capacity of at least 100 GW, which would truly help to solve the world's energy problem.

Mildura Solar Power Station is a concentrating photovoltaic (CPV) project being built in Carwrap, south of Mildura in the state of Victoria, Australia. The project will use high performance solar cells used to power satellites. The plant was proposed to have an installed capacity of 100MW initially to reduce the annual greenhouse gas emissions by 396,000t.

Green is the most efficient "semi-transparent" colour for producing electricity, although red and purple also work well. Oxford PV predicts that manufacturing costs of its product will be around 50% less than the current lowest-cost thin film technology and expects its new mechanism will eventually match the unsubsidised cost of electricity generated from fossil fuels.
