Solar Power Lab is engaged in research activities on different aspects of Photovoltaics.
A good surprise: Our SolMat paper on 40 µm-thick screen-printed heterojunction solar cells with 20.48% efficiency was news in PV-magazine!
Just published: Thin silicon and J0s 10x smaller than the sate-of-the-art are required to increase efficiency. Check: https://pubs.rsc.org/en/content/articlehtml/2020/ta/d0ta04575f
Just published: Great work of Joe Karas on reliability of Cu-plated solar cells and modules. Check: https://onlinelibrary.wiley.com/doi/full/10.1002/pip.3331
Just published: Great work of Pradeep Balaji on surface passivation of very thin silicon heterojunction solar cells.

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.
