Swiss researchers develop new process for back contact cell production

A team of researchers from École polytechnique fédérale de Lausanne (EPFL) and the Swiss center for Electronics and Microtechnology (CSEM) has developed a new process for fabricating cells with all electrical contacts at the rear. According to EPFL, the process has already achieved lab efficiencies in excess of 23%.

EPFL researchers investigate effect of light in perovskite cell formation

Scientists at Swiss research center École polytechnique fédérale de Lausanne have published research showing how the presence of light can affect perovskite film formation. The study could result in higher efficiencies and better reproducibility in perovskite cell production.

Video: Solar Superheroes return to SNEC

The Solar Superheroes made their live action debut at the SNEC show in 2016, and this year they returned, once again drawing huge crowds wherever they prowled or performed.

Japanese scientists seek to develop solar cell able to absorb spectral components of longer wavelengths

The new technology is designed to capture the spectral components of longer wavelengths that are usually lost during transmission through the solar cell. The Japanese scientists are using up-conversion of below-gap photons to reduce power losses and increase the cell efficiency.

Getting ready for terawatts of solar (with charts)

Researchers from NREL, Fraunhofer ISE and Japan’s AIST have released a new paper which looks at the barriers to deploying multiple terawatts of solar PV and what can be done to overcome them.

4JET launches CIGS processing tool

German equipment supplier 4JET microtech has launched its new MPCT solution which it says will enable laser edge deletion, bus bar exposure and via drilling operations in CIGS glass substrates.

Imec’s perovskite-based PV module reaches 12.4% efficiency

The Belgian research institute has improved the efficiency of its 4x4cm² perovskite module by 1.1%.

Schmid and MacDermid 2017 Technology Highlights award winners

Schmid Group and MacDermid Enthone have been selected as pv magazine’s 2017 Technology Highlights award winners. In late March, the prize jury of industry experts met to select the winners, from a shortlist of eight innovative new PV production equipment and materials. Dozens of entries to the award were received from suppliers worldwide. Alongside the two winners, the jury selected Sinton Instruments as worthy of special commendation as having provided the ‘Technology to Watch’ in 2017.

First Solar seeking sale of its share in yieldco 8point3 Energy

The Arizona-headquartered solar power company wants to strategically align its resources to support its new Series 6 module, and thus seeks sale of its stake in the joint SunPower yieldco. SunPower reaffirms belief that the yieldco can deliver long-term assets and growth.

ANU develops 26% efficient cell using perovskites

Researchers at the Australian National University (ANU) have achieved 26.4% efficiency using a stacked configuration of silicon and perovskite solar cells. The perovskite cell is semi-transparent and, according to ANU, could bring down the cost of generating solar power.
