In our opinion, nano-technology is the second renaissance. With the ability to work on materials a billionth smaller in size, many scientists enjoy significant improvements in their fields. One of the beneficiaries of nano-technology is Photovoltaics.

The group picture above belongs to the Javey Research Group, whose expertise lies in nano-technology. They have been applying this expertise on many topics, including Photovoltaics, since Prof. Ali Javey founded the group in 2006.

The team describes their work in Photovoltaics under High Performance and Flexible Photovoltaics title.

High Performance and Flexible Photovoltaics
Recognizing the vast potential of solar energy and its importance in the upcoming energy crisis, Javey Research Group started working on a 3D solar nanopillar cell, SNOP as they call it, which utilizes anodic alumina membranes as the template for the synthesis of single-crystalline nanostructures.

Even though the Javey Research Group’s efforts belong to the Thin-Film Technologies category in the following efficiency graph, nano-structured solar cells are relatively new and could be considered as a part of Emerging Photovoltaics category. This graph is from National Renewable Energy Laboratory (NREL) and the most recent version can be seen by clicking on this link.

Solar Energy

The first generation solar cells created by the Javey Research Group with nano-structures were able to get to 12% materials conversion efficiency and 6% device conversion efficiency. These are impressive numbers for the first generation solar cells. Aside from efficiency, there’s also a huge cost reduction potential with this approach. Growing single-crystalline structures on aluminium sheets as well as the 3D configuration of the crystalline nanopillars that lower the materials requirements could significantly lower the cost of the solar cell modules.
