Alternatives To Silicon In Solar Panels

Another metric in evaluating alternative solar photovoltaic materials is their commercial status.

Alternatives to silicon in solar panels. Previous tests of bismuth oxyiodide indicated that its efficiency may be too low for solar and it was also easily degraded in liquid electrolytes. Department of energy began to fund alternatives to silicon. The most common solar cells use silicon as a semiconductor which can transmit only one third of the energy because of the band gap which is the amount of energy needed to boost an electron from. Do you want to save energy and cut down on your electricity bills without fussing about solar panels.

Solar cells that are cheaper and easier to manufacture could challenge the dominance of silicon with new research showing an alternative material called perovskite is more efficient and adaptable. The alternate materials cdte and cigs are direct bandgap semiconductors and as a result have much high absorbtion for a given thickness than indirect bandgap silicon. Because of these complications researchers have been searching for less expensive alternatives to silicon solar cells that can be processed more quickly. Bismuth a silicon alternative for solar cells source.

Although alternatives such as dye sensitized cells and organic photovoltaics have good performance and commercial status silicon cells still outperform them. Figure 2 shows the commercial status and performance of alternative materials against silicon. If the hurdles of scale and stability can be overcome perovskite solar cells have the potential to change the economics of solar power as they are much cheaper to produce than silicon cells.
