Solar Cell Power To Weight Ratio

In this can project we propose to improve the space solar cell power to weight ratio by orders of magnitude using a novel technological approach.

Solar cell power to weight ratio.

This technique is usually restricted to aerospace applications where performance and a favorable power to weight ratio outweighs cost. In addition the power to weight ratio of the new devices is among the highest ever achieved for solar cells. Asti announced the company has achieved a major breakthrough in power to weight ratio for its superlight solar module delivering over 1700 watts of power. Solar cells technically known as photovoltaic cells.

Panel with 30 single junction gaas thin film cells was tested for application as battery charging device for the military 44. While there is some variation from brand to brand most panels weigh somewhere in the neighborhood of 40 pounds. However this success was possible because in the space application power system costs could be high because space users had few other power. Though flexible solar cells are hardly a new innovation even being produced experimentally in everything from continuously printed rolls to spray on panels the power to weight ratio is where.

Ascent solar technologies inc. Thin film tandem junction solar cells on thin plastic substrates which are capable of ultimately achieving conversion efficiencies of 30 yielding 35 40 mw cm 2 of power thereby. The expense can be mitigated to some extent by using low efficiency materials to build moderate efficiency three junction amorphous silicon solar cells. The cells flexibility and low weight in combination with a high cell efficiency can also be used for terrestrial applications especially if portable power is required.
