Technology and R&D

A new test design from the University of Central Florida has challenged modules with different cell technologies. The results show advantages for the heterojunction modules tested. Here we discuss the new method with its designer.

As solar comes to represent a larger proportion of the global energy mix, direct comparisons with conventional energy sources, and even with other renewables, are becoming more and more important. This is reflected in a bid by the United Nations Economic Commission for Europe’s (UNECE) Expert Group to standardize reporting on solar energy potential. Long Seng To, Royal Academy of Engineering research fellow at Loughborough University, and part of the UNECE solar energy subgroup, discusses the draft standards.

Tara Doyle started her career in the solar energy industry more than 15 years ago, and today serves as the chief commercial officer at PVEL, which claims to be one of the first testing laboratories to focus on bankability for the downstream PV buyer community. The lab serves developers, financiers, O&M companies, asset owners, and insurers.

An international team of researchers led by the University of Tokyo has discovered a new material which, when rolled into a nanotube, generates an electric current if exposed to light. If magnified and scaled up, say the scientists, the technology could be used in future high-efficiency solar devices.

Scientists at Germany’s Fraunhofer Institute for Solar Energy Systems have broken two of their own records for cell efficiency, working with silicon and III-V material tandem cells. The institute hit 34.1% on a triple junction cell using wafer bonding technology and 24.3% by directly depositing III-V layers onto a silicon solar cell.

With the benefits solar panels can bring to cropland being considered in Europe, PV and aquaculture are working in tandem in Vietnam. Shrimp and fish farming requires land and lots of water but solar panels are helping mitigate those demands.

Scientists at the Royal Melbourne Institute of Technology have developed a method for producing a ‘smart fabric’ with a supercapacitor energy storage device embedded in it. Its developers say it can be readily integrated with a solar cell or used to power wearable technology.

While based in Munich in Germany’s south, renewable asset management software provider 3megawatt’s first major clients were in the United States. However, as the European markets have transitioned beyond feed-in tariffs to the complexity of subsidy-free solar and wind arrays, the understanding of the need for asset management tools is rapidly increasing, says 3megawatt founder and CEO Edmee Kelsey.

X-ray analysis is said to have solved the mystery of how to preserve optical absorption in perovskite layers. Researchers say the discovery could help stabilize the material and speed up the launch of a new ingredient for PV research.

Two reports have described how the world’s largest renewable energy market is moving towards maturity. According to the Brookings Institution, the Chinese clean energy market could become more open to Western investors and tech. A report by Fitch claims projects are moving back to inland provinces from coastal regions.
