Eight19 may have come to the same conclusion but for now it expects Azuri to provide a route to maret for its printed plastic solar cells. We shall see.

Serious solar technology deployment requires heavy government involvement against very cheap natural gas that is even killing coal now, not to mention solar, wind, and other renewable sources of energy...therefore Africa is the last place on earth where you would deploy solar on a massive scale despite the fact they get lots of sun activity there...Kris

@Peter Clarke: the printed plastic solar cells are quite low in efficiency (most in single digits!) and is not the best choice for indoor lighting. I have seen many solar lanterns being sold in India that use crystalline solar technology that seem to do the job for 2 to 3 hours. Given volume production, these have better chances of seeing success than low cost printed solar. MP Divakar

This sounds like an adaptation of the ubiquitous solar landscaping lights. I think they are even less than $50. I've had some running for 7 years. Not bright enough to illuminate a table, for instance, but with today's technology they would be better and do more.

Worldwide, there is high pressure on solar subsidies, but in Africa, the price point of solar is below market rates. That said, this article is not about large scale solar but small scale solar for lighting primarily which is not subsidy driven. We are talking $50 (or less) lanterns that are leased. The cost of the lantern is covered by what would have been spent in kerosene.

Generally, it is not looking good for the solar marketh. With the debt crises, help is not coming from govts.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
