Recent work published at IEEE Journal of Photovoltaics. Lifetimes of (top) unmetallized SHJ precursor; and (bottom) Cu-plated SHJ cell. https://ieeexplore.ieee.org/abstract/document/8878168
Experimental and modelled emissivity results for (a) the complete SHJ cell and (b) the SHJ cell without the front ITO. The contributions to the emissivity of the different part of the cells (front, bulk, back and Ag) are shown, in addition to the total reflected power and the power reflected during the first interaction of normally incident light with the front surface (R0).

One of the biggest challenges holding back our spacefaring activities — from satellites and in-orbit manufacturing to bases on Mars and asteroid mining — is the lack of affordable space solar panels to power them.
By 2050 we’re going to have global broadband internet satellite networks, in-orbit manufacturing, space tourism, asteroid mining, and lunar and Mars bases.
More than a gigawatt of solar energy will be needed to power these activities, or the equivalent of 3.125 million photovoltaic panels. However, because it is currently the most expensive component on a satellite, scientists are looking for ways to make solar energy in space affordable — and to keep solar power systems from degrading so quickly in the extremely harsh environment of space.
Arizona. Where you don’t have to shovel sunshine, as the old tourism ads chortled. At Arizona State University, students and alumni are Sun Devils. The sun is in the university logo. Solar panels cover almost every structure.
Have you ever wondered how to make a solar cell in a research lab? We have put together a video for an in depth peek into the Solar Power Lab and shows how we make our record breaking solar cells. We describe the process from the bare silicon wafer to the final solar cell for our heterojunction cells, which have a record high open circuit voltage over 750 mV. Most cells made in indutry have a much lower voltage at 640-650 mV and use a process called phosphorus diffusion with rear aluminum back surface field (we have a pilot line for that too).

The US Energy Information Agency keeps detailed statistics on all forms of energy including solar power. The recently released data for 2017 shows that solar powers almost 2% of the US national electricity grid. What is remarkable is the high growth of solar with the amount of power produced doubling every two years. In 2015 solar electricity was less than 1% of the total electricity generated in the US. Two years before that (2013) the EIA did not even keep detailed statistics on solar, since the amount produced was so small.
