Solar cell technology development

Researchers from RTI international, and independent R&D institute, have recently developed new solar technology that could make solar energy much more affordable. The solar cells developed by RTI used low cost materials called colloidal quantum dots and processing techniques and could cost up to 75 per cent less than traditional solar cells. Currently, these cells have a conversion efficiency of 5 per cent as a result of the limitations to absorb sunlight, however, further developments are being made to the cells.
