TSEC modules adopt TSEC high-quality anti-PID solar cell/packaging material
* Improve quality: improve the characteristic of the ARC layer to improve the quality of the cells

Improve the PID effect: the PID (Potential Induced Degradation) effect means that after the cells constitute a solar module or power plant, the potential difference formed by these cell damages the solar cell or module (Leakage path), and then which further results in the decrease of the power generation performance of the cells.
On the contrary, the feature of the product is to improve the characteristics of the ARC layer (SI-rich), which can effectively improve the anti-PID effect and improve the quality of the cells.


* Increase efficiency: repair surface danglingbonds to better the efficiency of cells

The danglingbond on the surface of the wafer is just the electron which has yet to form the bonding. The danglingbond has high activity, which tends to form the trap centers and then results in the reconnection of the electron/hole pair. Accordingly, the life of the carriers will be reduced, so the conversion rate will be decreased.
The feature of the product is to repair the surface danglingbonds by annealing to improve the efficiency of the products.


TSEC modules pass strict TÜV Rheinland dual-85 PID test for 1000 hours.
* TSEC modules pass strict TÜV Rheinland dual-85 PID test for 1000 hours.





TSEC modules pass Taiwan ITRI salt mist corrosion test for 56 days, which proves TSEC modules can adapt to various poor weathers and environments.
* Salt mist test condition: IEC-60068-2-52

The description of one cycle test of one day (test duration: 7 days):
The first day ~ the fourth day: spray mist for 4 times and each time lasts 2 hours; afterward, keep the moisture for 22 hours for each (each for one day, 4 days in total)
The fifth day ~ the seventh day: keep it under common air
In total: 56 days (8 cycles X 7 days)



* The results before and after the salt mist tests

The output attenuation rate is almost unchanged before and after the test. 


TSEC modules pass Taiwan ITRI 10,000pa anti-wind pressure and anti-snow pressure test, which proves TSEC modules can adapt to various poor weathers and environments.
* IEC 61215, Ed. 2(April2005)



* Mechanical load test
TSEC adopts the current classification method to pervert from hot-spot effect.
* Hot-spot inspection method 1



* Hot-spot inspection method 2
TSEC adopts 3–stage EL test
* Example of EL inspection result


The so-called EL inspection is to use the EL (Electroluminescence) phenomenon to perform the inspection, which makes the current flows through the cell and then uses special camera to check whether there is microrack or poor electrode or other defects which cannot be identified by naked eye inside the cell via the light-emitting characteristic of the cell.

The defect or impurity of the cell may show different color in the image, which can be used to check the quality.


TSEC modules provide 25-year linear power warranty and 10-year product warranty to improve the overall output performance of the system.
* Warranty system of TSEC modules



10-year product warranty

When the solar module malfunctions, the repair or replacement of some modules are free within 10 years after the shipping date.


25-year linear power warranty

The Pmax of the solar module should conform to the conditions regulated by JISC8919.  If it is lower than the standard, the repair or replacement of some modules are free within 25 years after the shipping date.  (Please refer to the following figure.)







E-Cell & V-Cell Product Features
* All of TSEC cell products are PID-Free products, which can pass the PID test up to 1,000hrs. (Test conditions:-1000V, Temperature: 85℃, Moisture: 85%)
* TSEC cell products have obtained excellent feedback from customers over the world due to high quality, good performance, great stability and trusty reliability.


E-Cell cell product is a novel structure developed by TSEC development team, and its object is to improve the photon absorption rate, effectively enhance PID effect and conversion efficiency.

V-Cell product also has the various advantages of E-cell product; besides, TSEC R&D team successfully develops the mono crystalline solar cell with high conversion rate by improving advanced manufacturing process and introducing new material, which already can be put into mass production by using the current equipment of TSEC.  V-Cell manufacturing process can further reduce the surface recombination rate (SRV[cm/s]) to increase the open-circuit voltage, the surface reflectivity and the short-circuited current (Isc).

Product Advantage
* High parallel resistance: after the performance test, the products with parallel resistance higher than the standard will be selected; therefore, TSEC solar cell products can keep high output performance under low illuminance environment.
* Low inverse leakage current: the advantage can effectively reduce the risk of hot-spot and better the long-term operation quality and provide the protection function under shadow.
* Appearance with smooth color: the solar energy batteries are classified according to the colors, and their appearances have consistency.
* Excellent weldability: TSEC products adopt the material with good conductivity, which make the bus electrode easy to be soldered.
* Brilliant cell to module ratio: unique technology makes the solar cell have brilliant conversion rate.
* PID-free solar cell product: TSEC adopts the most frequently used method to set up the PID test and acceptance standard for single assembled cell; after optimized parameter adjustment, the solar cell can have good resistance against the PID test.  All of TSEC cell products are PID-free products, which have passed the PID test for 1,000hrs (-1000V, Temperature: 85℃, Moisture: 85%).
* Prevent the cell from being influenced by environment: TSEC solar cell can still have stable performance even if under improper environment (high temperature, high moisture, extremely cold). 
* Conform to RoHS/SVHC standard: RoHS/SVHC standard makes sure the Pb content of the products is within the safe range and conforms to various environmental regulations.
