Nano Solar Cells Efficiency

Nextgen nano s vision is to replace existing solutions with earth friendly biopolymers.

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. 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. 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. Various advances have incorporated nanotechnology into solar panels to simultaneously improve efficiency while also reducing associated manufacturing and installation costs.

Nanocrystal solar cells are solar cells based on a substrate with a coating of nanocrystals the nanocrystals are typically based on silicon cdte or cigs and the substrates are generally silicon or various organic conductors. While the power conversion efficiency of perovskite solar cells pvscs a future of solar cells has already greatly improved in the past decade the problems of instability and potential. Making solar electricity cost efficient mass produced and available in many versatile forms by reducing the cost to under 1 watt. Polypower combines advanced nanotechnology and biopolymer materials to produce an efficient solar cell.

Quantum dot solar cells are a variant of this approach but take advantage of quantum mechanical effects to extract further performance. Currently available nanotechnology solar cells are not as efficient as traditional ones however their lower cost offsets this. Developed proprietary process technology that makes it possible to produce 100x thinner solar cells 100x faster. 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.
