Comprehensive assessment of performance and reliability of PERC
Tunnel Oxide Passivated Contact (TOPCon) and Silicon Heterojunction (SHJ) solar cells are key technologies in the photovoltaic (PV) market, replacing Passivated Emitter and
We understood that HJT is technically superior amongst all the available technologies. However it is also important to compare HJT to the on-going passivated emitter and rear contact (PERC) technology. We simulated a 1 MW power plant in the state of Gujarat (refer Figure 2).
The PR of HJT based plant is 4.7%abs greater than the PERC based plant which clearly shows the advantages of utilizing HJT technology. With such advantages, HJT stands out tall when compared to its competitors in almost all the fields. Figure 2: Comparison between HJT & PERC Things to take care while making HJT
Heterojunction – The technological way ahead for solar PV! Solar cell for almost a decade had been stable with its size as M2 which was also the choice of end customer. However with the drive for enhanced power output alongside reduction in solar PV's levelized cost of electricity (LCOE), the need for change was inevitable.
A Heterojunction IBC cell is often abbreviated to HBC. A HBC structure has several advantages over conventional SHJ cells; the major advantage is the elimination of shading from the front grid, which improves light capture and hence short circuit current density .
