The efficiency of photovoltaic technology is advancing by leaps and bounds, the latest innovation has been presented this 2023 with the TOPCon photovoltaic modules.
We could say that TOPCON is, an advanced N-type silicon cell technology, which means (Tunnel Oxide Passivated Contact), it combines an oxide layer with a PERC solar cell to further reduce recombination losses and increase the efficiency of the solar cell, It is therefore not surprising that this technology is causing a stir within the renewable energy sector.
Some of the advantages of TOPcon technology
- Continued efficiency improvement over previous technologies through increased light absorption leads to LCOE and shorter payback periods
- The structure of the oxide layer further minimizes electron recombination, greatly improving cell conversion efficiency, with an upper limit of 28.2% to 28.7% (cell efficiency, not panel efficiency).
- Improved temperature coefficient
Customizable manufacturing process
TOPCon N-type high-efficiency components, using 182mm large-size silicon wafers, can meet the needs of different scenarios, such as distributed residential rooftops, industrial and commercial rooftops, and centralized power station projects. In terms of efficiency advantages, N-type TOPCon modules are higher than P-type monocrystalline PERC modules, which means that more non-silicon materials and manufacturing costs can be saved on the module side. On the other hand, thanks to the higher efficiency and power of the module, the use of TOPCon N-type modules can use less components, grounds, columns, supports, cables and inverters, save system BOS costs, and achieve higher installed capacity under the same facility. area, thus increasing the profitability of the plant.
As stated above, TOPCon looks a lot like a modified version of PERC cells. Therefore, TOPCon solar cells can be easily manufactured by adding some additional processes to the well-developed PERC manufacturing processes and product lines. This compatibility between the two technologies means that adopting TOPCon technology is more accessible to those who already use PERC cells.
TAMESOL will start production with an output power up to 580W
At TAMESOL we have incorporated into our family of products the N-ype TOPCon technology, which offers a combination of unmatched efficiency, relatively low cost, and the ability to easily adapt to existing module design parameters.
TAMESOL’s TOP series range includes photovoltaic modules with power ranges ranging from (410W-430W) based on 166 mm cells, with an efficiency increase to 21.99%, and (560W-580W) based on 166 mm cells. of 182 mm, with an increase in efficiency to 22.44%. Modules with TOPCon technology will start mass production this second quarter of 2023. It is planned to gradually increase the power ranges.
TOPCon modules will consolidate technology and product leadership at TAMESOL, while further increasing customers’ return on investment:
- TAMESOL’s temperature coefficients are as low as -0.30%/℃ and therefore TOPCon modules will have better performance in hot environments compared to mainstream products on the market.
- There is no LID (Light Induced Degradation) related to Boron and Oxygen, therefore TOPCon modules will have less power degradation.
- 30-year performance guarantee
TOPCon technology is a breakthrough in photovoltaic efficiency. Several solar module companies have already upgraded their production lines, with more planning to do so soon. Therefore, the renewable energy industry can expect TOPCon to grow and become as universal as PERC technology.
