In a pv magazine interview, Trina Solar’s vice president and chief scientist Pierre Verlinden talks about the latest development in the improvement of solar cells and modules.
Questions:
00:10 – How many people work at Trina Solar’s State Key research lab?
00:35 – How deep are your investigations onsite? E.g. the deposition methods?
01:37 – You once said production costs decrease by 7 % and relative efficiency increase by 2 % annually. Do you still achieve this?
01:51 – How much of the cost reduction is related to cell improvements and how much to module improvements?
02:35 – Is this cost reduction because of the relative efficiency increase of around 2 % per year?
03:11 – How did you achieve this increase in productivity?
03:35 – Should customers care about which technology is used? E.g. Perc or standard modules
04:28 – What do you do to further increase the yield of the modules?
05:09 – And project investors are willing to pay extra for the premium glass-glass-modules?
05:58 – Can PID effects occur even if modules are labeled “no PID”?
06:22 – New technologies tend to come with new risks. Do investors have to be aware of these, when applying PERC modules, for example?
07:33 – For mono PERC the LID problem seems to have been solved. What about LID and multi PERC (LID = Light Induced Degradation)
08:24 – Due to a recent price drop, mono wafers are more attractive then multi wafers, aren’t they?
10:37 – So there is no reason to switch to n-type anymore?
