The P-type solar cell (mainly the PERC solar cell), which has a simple manufacturing process and lower cost, is popular in the PV sector.

SHANGHAI, Apr 23 (SMM) - The P-type solar cell (mainly the PERC solar cell), which has a simple manufacturing process and lower cost, is popular in the PV sector. The average mass production efficiency of PERC solar cells is 23.2%, approaching the theoretical conversion efficiency limit of 24.5%, which means that it is difficult to greatly improve the efficiency of PERC solar cells.

Compared with the traditional P-type solar cell, the N-type solar cell has high conversion efficiency, high bifaciality rate, low-temperature coefficient, almost no light decay, etc. The mainstream N-type solar cell includes TOPCon solar cells, HJT solar cells, IBC solar cells, etc. The TOPCon solar cell has high limit efficiency and low cost of production line transformation; HJT solar cell has high mass production efficiency and a clear cost reduction route; IBC solar cell has higher conversion upper limit but low cost efficiency.

[SMM PV News] US Wind and Solar Hit Record 17% of 2025 Power Mix

Combined US utility-scale wind and solar generation reached a record 17% of the electricity mix in 2025, producing 760,000 GWh. Utility-scale solar drove this surge, jumping 34% year-over-year. Including small-scale solar pushes the combined 'wind and solar' share to 19%. As electricity demand rises—fueled by data centers and electrification—the grid is preparing for a historic 86 GW of new capacity in 2026, with solar and battery storage making up 79% of these planned additions.

[SMM PV News] UK Tightens Rules as Smart Meter Rollout Slows Ahead of 2030 Target

Smart meter deployment in the UK has hit a slump, prompting the government to introduce stricter regulations for energy retailers to ensure full domestic coverage by the end of 2030. While 21.8 million smart electricity meters were operating by the end of 2025, 7.8 million traditional meters still need replacing. To meet the 'Clean Power 2030' target, suppliers must submit binding annual deployment plans to Ofgem, replace outdated 2G and 3G meters before the 2033 network switch-off, and adhere to a strict 90-day window to repair faulty units or face penalties. This regulatory push aligns with the UK's broader efforts to integrate residential batteries and EVs into grid flexibility markets.
