Summary:
Scientists have created and characterized a photovoltaic device based on a combination of titanium oxide and graphene as charge collector and perovskite as sunlight absorber. The device is manufactured at low temperatures and has a high efficiency.

The Group of Photovoltaic and Optoelectronic Devices (DFO) at the Universitat Jaume I in Castelló, led by the professor of Applied Physics Juan Bisquert, together with researchers from the University of Oxford, have created and characterized a photovoltaic device based on a combination of titanium oxide and graphene as charge collector and perovskite as sunlight absorber. The device is manufactured at low temperatures and has a high efficiency.

The results of this study were recently published in Nano Letters. The article is the result of the research work carried out the last year by the Group of Photovoltaic and Optoelectronic Devices on the topic of photovoltaic solar cells based on solid pigments with perovskite structure.

This scientific work has combined new and promising materials based on perovskite structure, which absorb sunlight very effectively, with graphene, a material of great interest today for its properties, versatility and low cost. Graphene is a material consisting of carbon monolayers. Its use has generated high expectations in new advanced technologies, such as high-performance lithium batteries, electronics, video screens and technological applications.

The paper presents a record of efficiency of a solar cell with graphene of 15.6%. This efficiency exceeds that obtained by combining graphene with silicon, which is the photovoltaic material par excellence. This development is a new milestone for the progress of perovskite solar cells.

Researchers Eva Barea, Iván Mora and Juan Bisquert have explained that the new device consists of several layers processed at temperatures below 150°C. They have also highlighted the importance of this study for the field of photovoltaic energy because they have obtained a high degree of efficiency. Besides, the device is manufactured at low temperatures, thus facilitating its large-scale manufacturing in industry. In turn, this fact means lower production costs and the possibility of using it in devices based on flexible plastics.

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) — When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
