Scientists from Purdue University claim to have created a new material that incorporates both organic and inorganic materials. Its hybrid structure is said to improve the thermal stability of perovskite PV cells without the need to use lead.

Ofgem passed its long-awaited, controversial plan for network charges last week, despite earlier warnings against the move. The UK electricity market regulator’s Targeted Charging Review has provoked a backlash in the renewables sector, as many believe that the plan will damage the economics of distributed energy resources and unsubsidized onshore wind and solar development.

JinkoSolar has announced that it will supply 300 MW of its Tiger solar panels for what it describes as an ultra-high voltage demonstration plant in China’s Qinghai’s province. The project will be connected to an ultra-high voltage power line that State Grid Corp. of China is building to connect the far northwestern part of the country to the more heavily populated eastern provinces.

A recent study shows that PV costs have declined faster than any other energy technology over the past two decades. The researcher behind the study said this would not have been possible without the “butterfly effect,” which is based on the idea that a small change in one part of a complex system can have a large impact elsewhere. The researcher also attributed the the rapidly declining cost of PV to Chinese manufacturing and strong US investor support.

A research group in Okinawa, Japan has been able to observe and characterize structural defects in an organic-inorganic perovskite solar cell. Their findings could help to inform future approaches to optimizing and improving perovskite stability.

A new paper published by the U.S. National Renewable Energy Laboratory delves into the potential of hybrid power plants combining wind and solar generation. Development of such plants, according to the lab, is driven by the need to increase profitability and consider metrics beyond levelized cost of electricity, taking into account time varying revenues and better managing these renewables inherent variability.

Researchers at the Massachusetts Institute of Technology have developed a transparent coating they successfully incorporated into a perovskite solar cell, increasing efficiency and stability. The group says with further improvements the material could be used as a simpler, less expensive alternative to widely used indium tin oxide as a transparent conductive material for a range of applications.

Three energy associations, including Holland Solar, have asked the Dutch parliament to take action amid worsening grid connection problems for renewable energy projects in the Netherlands. According to the energy groups, around 700 MW of solar and wind projects allocated under the SDE+ incentive program could lose their payments if they miss connection deadlines.

The project was realized by the i-DE distribution company of the Spanish electric utility. The large scale storage battery is intended to improve the quality of electricity supply with a focus on solar projects located nearby.

The European Bank for Reconstruction and Development is offering the funds to Egypt’s transmission system operator to strengthen the country’s grid to host more renewable energy in anticipation of rising power demand over the coming decade.
