The 11th edition of the German document which tracks solar price falls and efficiency improvements has considered the role bigger wafers are playing in cost reduction.

Russian researchers have improved the efficiency of a thin-fim GaAs‐based solar cell by 0.9% by applying single‐walled carbon nanotubes as the topmost layer. The cell also showed a slight increase in the short circuit current density, from 16.9 to 17.9 mA/cm2.

French organic PV module manufacturer Armor said it began manufacturing free-form PV modules in early April. The new technology will allow the company’s ASCA PV film to be produced in a range of different shapes.

Atamostec, a private-public initiative supported by Chile’s government-run Production Development Corp. and several industrial partners, has developed a new module. The team claims that the bifacial panel offers an additional annual average gain of 11% compared to monofacial PERC modules with the same cell technology.

A group of researchers from India is trying to apply a special phase change material to regulate temperature in copper, indium and selenium solar panels. Phase change materials are substances that are capable of storing thermal energy, allowing for the stabilization of temperature.

Hungarian tech company Platio has developed solar pavement for outdoor applications in urban environments, homes, office buildings, shopping malls, and public infrastructure projects. The pavement consists of solar tiles that may cost between €50 and €80, depending on the size and characteristics of projects.

Researchers from Finland’s Lappeenranta University of Technology have assessed the economic advantages of a fully interconnected global network. They found that an international grid could contribute to a global LCOE of €52.50/MWh. The higher complexity of such a system, however, would only be marginally compensated by additional economic benefits.

The installation will be located in the Changbin Lunwei East district. A NT$7.2 billion loan was secured from a consortium of seven banks and the solar facility is expected to be grid-connected this year.

A U.K. study has identified 13 soiling agents with differing effects on light transmittance. Researchers found some dust particles were able to degrade photovoltaic performance by as much as 98%.

Solaria says that it will start selling its new all-black panel for residential PV applications in the U.S. market within the current quarter. The monocrystalline module is equipped with a microinverter from Enphase and has an efficiency rating of 20.2%.
