New metallization tech to reduce microcracks in solar cells
A U.S. research group has developed a metal-carbon-nanotube composite – MetZilla – which can be embedded in commercial, screen-printable silver pastes and is said to reduce the formation of hotspots in solar modules and to prolong panel lifespan. The composite metal contacts are also ‘self-healing’ as they are able to regain electrical continuity after cycles of complete electrical failure caused by extreme strain.

Solar cells made of fully inorganic perovskite materials show higher durability
As William Marsh Rice research university scientists say, PSC can be manufactured under outdoor conditions, remain intact during months and have an efficiency exceeding 12 per cent, in case we use In instead of part of plumbum. Such an alteration will as well diminish defects that give negative impact to the solar panel bandgap.

Novel Solar Cells Arrive at International Space Station for Testing
Five different types of solar cells fabricated by research teams at the Georgia Institute of Technology have arrived at the International Space Station (ISS) to be tested for their power conversion rate and ability to operate in the harsh space environment as part of the MISSE-12 mission. One type of cell, made of low-cost organic materials, has not been extensively tested in space before.

The French association creates a hybrid energy storage and cogeneration solution
Smart Energy Hub system can work both as an electrolyser and as a fuel cell. In the first case, it stores energy in the form of biogas. In the second case, it converts gas into heat and electricity. The system has been developed by Sylfen and French Alternative Energies and Atomic Energy Commission.

Straining to fix perovskite cells
A technique based on optical imaging has been used by an international research team to illuminate strains in lead halide perovskite solar cells without harming them. The scientists claim the approach helped them discover misorientation between microscopic perovskite crystals was the main cause of the strains.
