Damp Heat Induced Degradation of Silicon Heterojunction Solar Cells With Cu-Plated Contacts. Check:

In the figure we show lifetimes for unmetallized SHJ precursor wafer (top) and a Cu-plated SHJ cell ((bottom) for diffrent DH test time. Unmetallized wafer lifetime is measured via QSSPC, while cell lifetime is measured via Suns-VOC. Both samples are encapsulated with glass-backsheet.

Latest results on thin silicon solar cells research developed at Solar Power Laboratory was presented by André Augusto at EU PVSEC 2019 in Marseille, France. Implied-Voltages over 770 mV were experimental demonstrated. This research has contributions from the PhD students Pradeep Balaji and Joseph Karas.

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.

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.

photovoltaic module efficiency records

A new publication highlights the progress in photovoltaic module efficiency. Previously, efficiency has focused on the smaller solar cell but a practical product requires combing the solar cells into a larger module. The publication includes the most recent photovoltaic module records as well as the historical context.
