With the absorption of ‘hot’ charges, which lose their energy faster than it can be absorbed by any convention technology, solar cells could become massively more efficient. An international group of scientists has developed a method to examine the bond between a perovskite and charge extraction layer, and determine the most suitable materials for hot charge extraction in a solar cell.

Manufacturers and research institutes from across Europe have announced plans to collaborate on creating improved processes for CIGS module production. Optimistically named SUCCESS, the project targets production line efficiencies of better than 20% for 30x30cm modules.

Chinese-German JV Nice Solar Energy has set a new world record of 17.6% efficiency for a CIGS module with a 0.72m² surface. The achievement has been confirmed by German testing organization TÜV Rheinland.

Researchers at the U.S. Argonne National Laboratory have applied a combination of machine learning and artificial intelligence to help narrow down a list of 166 billion molecules that could be used to form the basis of a battery electrolyte. The technique, say the researchers, offers a way to greatly reduce the cost of narrowing down such an enormous data set, while still providing a precise understanding of each molecule and its likely suitability.

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.

In our recent webinar, held in partnership with JinkoSolar, on the impact of bifacial modules and modelling their yield under varying environmental conditions and system setups, JinkoSolar’s Andrea Viaro discussed innovations in bifacial module design, and implementing these into a system to positively impact the return on investment. Teun Burgers, a Senior Researcher at ECN.TNO also delved into the simulation of bifacial PV systems, and treated us to a closer look at ECN’s BIGEYE simulation model. Here, the two presenters answer some more of the questions posed by the audience during the webinar.

German headquartered PV manufacturer Aleo Solar has announced plans to introduce the module in the new year. Like many of its rivals, the company is moving to a larger cell size for the new product, which it says will offer up to 333 W output from a 60-cell format.

Scientists at the University of Houston in the United States have developed a new catalyst which they say can efficiently produce hydrogen from seawater. The group says that its discovery significantly advances the development of seawater electrolysis for large-scale hydrogen production.
