PV

Mathematicians at Canada’s University of Waterloo who turned their attention to solar power have developed an algorithm they say offers better control over PV plant output. The researchers estimate the algorithm could improve the output of a 100 MW power plant by almost a million kilowatt-hours per year.

The Uzbek government last week opened a rooftop solar program which provides 30% of the initial costs for buying and installing a PV system, up to around $320 per project. Tax incentives are also available.

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.

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.

International data suggests that fires caused by rooftop solar power systems are rare; however, the United States doesn’t centrally track this information – with the National Fire Data Center classifying them in the “other” category.

According to official statistics produced by the nation’s National Energy Administration, China’s cumulative installed PV generation capacity had reached 185.5 GW at the end of June.

The performance of the company’s Selectively Coated Ribbons was measured for more than a year in a field test. Heraeus says the yield gains are achieved by the device’s optical properties – said to enable improved reflection – even at low angles of incidence and in low-light conditions.

Poland’s second largest power company, Tauron, wants to build a 5 MW ground-mounted facility in Jaworzno and is seeking EPC contractors through a tender. The project is part of the company’s plan to deploy PV on its unused sites.

Meyer Burger’s new chairman has acknowledged that the outlook remains tense for Europe’s largest solar equipment supplier, but he is urging shareholders to support the company’s plan to reposition itself to focus on high-yield technologies and markets beyond China.
