Fabrication of a 22.8% Efficient Back Contact Solar Cell With Localized Laser‐Doping

Abstract: Interdigitated back contact (IBC) solar cells offer one of the most promising routes towards highest device efficiencies but require finding of industrially feasible low cost production sequences. In this paper, the fabrication of a 22.8% efficient all-laser-doped IBC solar cell with localized boron and phosphorus doped contacts is reported. The laser-based approach with localized emitter and back-surface field regions reported here avoids costly patterning steps of the localized contacts. By means of numerica… Show more

“…[34,37,38] Furthermore, techniques such as localized laser doping process on the rear surface, the incorporation of bifacial structures, and advanced metallization techniques have also been employed to enhance the efficiency of PERC-type cells. [39][40][41] However, addressing challenges such as light-induced degradation (LID) and thermally-assisted degradation (LeTID), especially under elevated temperatures, is crucial for ensuring the long-term stability of p-PERC cells. [42][43][44][45][46][47] Therefore, exploring measures to prevent various degradation issues in p-PERC solar cells remains critical for their future practical application and sustained success.…”

“…Transferring such technologies to industry requires substituting complex photolithographic patterning with low-cost, high-throughput processes for local contact formation. Laser-based processing has emerged as the preferred solution for this problem [3,4].…”

“…T HE NEED to align locally applied processes to each other has become a major challenge in solar cell fabrication, since the trend goes to high-efficiency solar cell concepts [1], such as the passivated emitter and rear cell (PERC) with selective emitter [2]- [4], or, e.g., the interdigitated back contact cell [5], [6]. Especially laser-based approaches, such as the laser-doped selective emitter (LDSE) [7]- [9], the PassDop [10]- [12], and the FoilMet-Connect [13] approach, might lead to a boost in solar cell efficiency, but come along with the challenge to align two patterning processes to each other.…”
