Maximum demonstrated efficiency in monocrystalline silicon cells[edit]

I think Monocrystalline silicon factors meeting dificulty now.

I'd like to point out that this page erroneously states that monocrystalline silicon solar cells have a maximum efficiency of 17%. This is clearly not true, as advances prior to the 2006 article were numerous, and many of them with over 20% efficiency. 2A00:C440:20:2E1:7145:11FA:52B5:4EBE (talk) 11:48, 3 December 2012 (UTC)[reply]

Chinese solar engineers at Jinko Solar achieved record 22.61&% PV efficiency in mono-PERC-cells with Passivated Emitter and Rear Cell (PERC) technology at its State Key Laboratory of PV Science and Technology of China ^[1] That is approximately one-third improvement in the record through merely four years of laborious PV research in China - 22.61/17 = 1.33 (a one-third improvement).

Solar charger segment[edit]

The mention of the use of mono-crystalline panels in "solarJOOS" phone chargers seems erroneous / out of place and possibly an example of commercial interference on wikipedia. I will leave this message up for one week, If there is no objection in the mean time I will remove the offending segment. I will try to bulk out the page with more relevant facts at the same time to make it slightly more useful. — Preceding unsigned comment added by 58.105.234.127 (talk) 14:55, 7 February 2013 (UTC)[reply]

Commercial use of Wikipedia[edit]

I don't agree that some people use wikipedia for commercial uses. I'll delete the mention of Solar Joos. — Preceding unsigned comment added by 190.160.211.195 (talk) 13:20, 5 March 2013 (UTC)[reply]

solar cells section[edit]

The solar cell section is way out of date. Crystalline Si is over 20%, and thin films are nearing 20%. I suggest a "more info" instead of a paragraph. — Preceding unsigned comment added by 158.12.18.125 (talk) 13:57, 1 May 2013 (UTC)[reply]

300mm to 450mm[edit]

I updated the "up to" cylinder size to 45cm; it's certainly not a common size yet, but it is in production and enough of it is currently made into 450mm wafers to qualify it as a genuine industrial product and not a custom, one-at-a-time size. Scutigera (talk) 18:28, 15 June 2013 (UTC) and also remember the main use of monocrystaline, we can use it as reflector also.. on the basis of that, make a "KHATARNAK" project. 27.251.235.194 (talk) 09:02, 29 September 2015 (UTC)[reply]

Missing advantages/disadvantages[edit]

So what are the advantages / disadvantages vs competing technology? Performance under full-sun/cloudy/shadow conditions? 132.160.49.90 (talk) 04:22, 9 February 2016 (UTC)[reply]

Efficiency record to-date[edit]

How much mono-Si has been produced each year[edit]

How much mono-Si has been produced each year ? Is it going down because of less demand for mono-Si from PV ? Silicon seems to say annual production for semiconductors (are they including PV ?) is about 200,000 tonnes pa. - Rod57 (talk) 12:31, 11 September 2021 (UTC)[reply]

Mono-Si is no longer going down; in fact, it has almost replaced poly-Si.
