For PCE measurment, I attacched Si cells at one side of LSC ( please see at the attached pictures), I got some PCE around 1.5% but i wonder whether or not the PCE achieved from LSC device ? Im going to measure Si cell without LSC by simulated illumination from the back side of Si cell as show at picture 5.
If you are working on LSC, please give a tip how could we confirm that? also how to avoid light absorption of Si cell, how to optimize LSC?
Thank you very much.
wish your research the best
I would propose to cover the side of the solar cell which is not subjected to the collected radiation by a a black adhesive film. This will prevent exposing the back side of the solar cell. You can also do the same with the collector.
I think the purpose of the experiment is to show the gain in the solar cell efficiency by using such collector. That is one wants to get the solar cell efficiency with and without the collector. In the normal construction the back of the cell is opaque but with the collector it is subjected to collector increasing the harvested energy.
wish you success
Actually I am not working on LSC, and perhaps for this reason the photos are not clear to me. However I have made experiments /measurements of power and efficiency of modules made of silicon outdoors under real conditions. I supose that if you could make the figure showing the entire set up someone could answer to the points you ask.
good luck to your research
