Nano Solar Cells Efficiency

Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.

Nano solar cells efficiency.

Various advances have incorporated nanotechnology into solar panels to simultaneously improve efficiency while also reducing associated manufacturing and installation costs. Efficiencies for current production panels are said to be 8 9 with plans to submit panels with 10 11 efficiency for iec certification in the fall of 2010. Despite this promise various challenges still exist in manufacturing nano based solar panels as a result of the current limitations in manufacturing nanomaterials at an. Making solar electricity cost efficient mass produced and available in many versatile forms by reducing the cost to under 1 watt.

Nextgen nano s vision is to replace existing solutions with earth friendly biopolymers. The efficiency of the solar cells used in a photovoltaic system in combination with latitude and climate determines the annual energy output of the system for example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200. Developed proprietary process technology that makes it possible to produce 100x thinner solar cells 100x faster. Polypower combines advanced nanotechnology and biopolymer materials to produce an efficient solar cell.

In the long term nanotechnology versions should both be lower cost and using quantum dots should be able to reach higher efficiency levels than conventional ones. Quantum dot solar cells are a variant of this approach but take advantage of quantum mechanical effects to extract further performance. To create solar cells nextgen nano uses biopolymers which are organically grown materials with polymer properties such as a crystalline structure and covalent bonds in a pattern. Nanosolar s solar cells have been verified by nrel to be as efficient as 14 6 in 2006 15 3 in 2009 and 17 1 in 2011.

Breakthroughs achieved by nextgen nano s polypower team could prove a critical step in producing a new generation of solar cells with unrivalled efficiency at significantly lower cost than traditional solar panels.
