[edit] Tesla

The Tesla device used the photoelectric effect, not the photovoltaic effect. — Omegatron 21:56, 22 February 2007 (UTC)

[edit] Efficiencies

Under what conditions are the efficiencies measured? It should be consistent for any quoted efficiency on the same page. — Omegatron 21:56, 22 February 2007 (UTC)

It isn't possible to make them all entirely consistent on an historical timeline. Measurement standards have changed over the years, for one thing: The standard used for terrestrial cells today is based on characterization of the Earth's atmopshere in 1970s and '80s, and was revised slightly in (I think) 2005. Conditions can also differ depending on the cell's intended use. Cells used in space are measured using the solar spectrum as it exists in space, while terrestrial cells are measured under a solar spectrum that accounts for the effects of the Earth's atmosphere (efficiencies measured under space conditions are a bit lower than those measured under terrestrial conditions). Concentrator cells are measured under concentrated light with a spectrum that excludes light scattered by the atmosphere, since the optics on those cells reject all but the direct component of the incident light.--Squirmymcphee 17:05, 18 July 2007 (UTC)

[edit] Merge with Timeline of photovoltaics

Agree, merge. Greenman 14:22, 1 June 2007 (UTC)

Merge was a good idea, but wouldn't Timeline of photovoltaics be a better title? The entries for recent years contain much that is around economics and deployment rather than the science of the cells themselves. Itsmejudith 15:53, 4 December 2007 (UTC)

[edit] PV production 1976-1994

This source [1] doesn't completely agree with numbers here[2], here [3] or [4] but the numbers are close and it lists data for many more years than any of these sources. The yearly production numbers from 81-94 are 5,9,15,17.5,19,21,25,31.5,38,43,48,54,56,61. And the data is given specifically in 1994 dollars which helps. Mrshaba 14:20, 4 November 2007 (UTC)

[edit] PV production and prices

Not sure where to post this message so it's going in several places. The PV articles would be greatly enhanced if we could develope a graph showing the historic prices for PV. The image below shows how the prices should be both real and inflation adjusted. As a companion to the price graph we also need a production graph.
