Meaning of anomalous photovoltaic effect?[edit]

What is meaning of anomalous photovoltaic effect?Will it allow to build highly efficient solar cells or what? Does materials only sometimes produce very high voltages or constantly? How greatly efficiency of solar cells could be improved? —Preceding unsigned comment added by 70.73.149.123 (talk) 03:03, 15 May 2009 (UTC)[reply]

Currently, as far as I know, the currents achieved in all these materials are very small and therefore a highly efficient solar cell cannot be achieved at the moment. However, understanding the mechanisms that allow such high voltages to be created in these materials, may allow the implementation of those mechanisms in a lower-resistance materials.

The type of anomalous photovoltaic effect discussed in this article is basically a series sum of an enormous number of microscopic solar cells. This will always, in principle, have lower efficiency than an one big solar cell, because current-matching will not be perfect, i.e. each mini-solar cell has a different "maximum power point" and it is almost impossible that all of them can simultaneously operate at their own maximum power point. In practice, that's what happens, it's much much lower efficiency, i.e. the current lowering overwhelms the voltage gain. So you would never use these things to generate a lot of electrical power. They may be useful in some niche application where very high voltage is important but only a very low current is necessary...one example of an application like that is pyroelectric fusion. --Steve (talk) 01:13, 8 January 2011 (UTC)[reply]

Assessment request[edit]

My wife created this article, because she couldn't find any related information in Wikipedia.

I helped her with Wikipedia technicalities, but i don't know anything about physics, so i can't help her improve it more.

It needs assessment - is it acceptable per "no original research"? The article is based on her master's thesis, but it is referenced.

It may also need better context. We tried to create an opening paragraph that fits the Wikipedia style, but i feel that it can be better.

Thanks in advance. --Amir E. Aharoni (talk) 15:54, 30 January 2008 (UTC)[reply]

I think this article needs some graphs, charts, pictures to substantiate itself. The article also basically starts off with a rather remote concept that the average layman won't understand...

The 2nd part on the existing model is still pretty complex...

The link on the Dember effect also needs some more explanation, more context and material.

Actually, I still dont get what these models mean, because the only photovoltaic effec I know is the Solar cell.

Perhaps some kindoff graphical explanation might spice up this article alot more.
