In the past few years solar photo-voltaics have undergone rapid changes in efficiency and cost. Currently the research being conducted by competing companies is improving the efficiencies and reducing the production cost. The industry itself is growing quickly and due to large scale manufacture prices are decreasing.

One of the ways to reduce the cost of solar cell production is to improve the efficiency of the cells as this enables them to convert more energy from the sun. New efficiency records are constantly being set by the leading companies in solar cell research. Some new developments are listed below (for more see our briefing note): Read more…
