Organic dopants for a stable perovskite
Researchers at Saudi Arabia’s King Abdullah University of Science and Technology have demonstrated a method they say could improve the stability of perovskite structures. The group found adding an organic dopant served to increase the strength of chemical bonds between organic and inorganic elements of a perovskite.

What is wrong with Fe photovoltaic cells
Scientists at Swedish Lund University are exploring the process due to which about a third of Fe-based solar cells’ energy is wasted. Identifying the way charge loss happens, they insist, is going to be the initial move toward solving the problem and creating high-efficiency photovoltaic cells of cheap and available material.

Newly developed material for radiative cooling of photovoltaics
The researchers from Spain have developed a material claimed to provide radiative cooling as well as self-purification of e-devices which are subject to critical heating when operating, such as photovoltaic cells. The heat emitter allows decreasing the day-hours temp of the silicon substrate by about 14 degrees C.

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.
