Isn't it ironic that it took so long for the PV market to reach the high volumes needed to drive down cost-per-watt, the solar power holy grail, and the next step is oversupply? But actually, that's the way of semiconductor-based technologies, and the majority of PV solar cells are based on polycrystalline wafers. It will be interesting to see how different the curves may be for thin-film or some of the more exotic competing technologies.

Great point, Chuck, about overcapacity, which presages an expected shakeout in the PV market, particularly insofar as high-flying startups are concerned. For a relevant article on this, take a look at Loring Wirbel's recent post, Solyndra Seeds Doubts About Photovoltaic Manufacturability.

Given the PV market's current level of overcapacity, every cost-reduced component -- connectors and cables included -- is important.

Connectors and cables are often one of those overlooked areas in a system design, or at least looked at last when there's no more budget left to do them right. In consumer electronics, it seems that the cheapest parts are spec'd in as the "afterthought" components. I agree, Alex, interconnects are vital, all the way from the chip's internal connections to the panel's external ones.

One interesting point that this post speaks to is that fact that core electronics functionality is worth nothing if you can't interface it to the outside world. Here we read about the importance of connectors for photovoltaics, particularly robust connectors for the harsh environments in which PVs cells are typically used. But this also applies to the internal construction of the PVs themselves, in terms of the bus-bar foils and the adhesives used in assembling the different layers of the PV cell. Interesting stuff!

Practically all electronic devices today contain metals that may be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Conformal coatings present themselves as space-saving alternatives to enclosures for protecting the circuit boards of automotive electronics. They can also provide electrical insulation.
Design for manufacturing (DFM) in mold production means that mold designers evaluate the manufacturability of their molds in the early stage of mold development by collecting all relevant information and applying it to their designs. They also have to consider many other factors, including flow balance, structural stress, and assembly tolerance, in order to ensure successful molding production.
Some adhesives provide strong structural bonds but take hours to fixture and attain handling strength. The technologies that offer the fastest cure do not bear loads or withstand stresses. A new class of adhesives aims to make both stick.
The continued growth of wireless health is a near-certainty. And engineers will be the key to developing and advancing technology solutions.
