Influence of laser power on POCl3 diffused back surface field on n-type PERT silicon solar cells with local back contact

Autor: Junsin Yi, Hoongjoo Lee, Jae Woo Choi, Kyuwan Song, Minkyu Ju, Cheolmin Park, Nagarajan Balaji

Publikováno v: Current Applied Physics. 13:1397-1400

We report n-type passivated emitter rear totally diffused (PERT) silicon solar cells with local back contacts (LBC) formed by laser process. With passivated back surface field (BSF), the PERT cell design shows an improved open circuit voltage ( V oc

Boron Oxygen Pair Effect in p+ Emitter and Nanosized Boron Rich Layer by Fold Coordination Analysis for Crystalline Silicon Solar Cell Applications

Autor: Youn-Jung Lee, Nagarajan Balaji, Bonggi Kim, Junsin Yi, Cheolmin Park, Hoongjoo Lee, Minkyu Ju

Publikováno v: Journal of nanoscience and nanotechnology. 16(5)

N-type substrates possess better material characteristics than p-type substrates for high efficiency mass producible Si solar cells with HIT, IBC structures. The major drawbacks of these structures are a complicated fabrication process and an expensi

Front-side metal electrode optimization using fine line double screen printing and nickel plating for large area crystalline silicon solar cells

Autor: Junsin Yi, Hoongjoo Lee, Minkyu Ju, Shihyun Ahn, Nagarajan Balaji, Jonghwan Lee, Bonggi Kim, Taeyoung Kwon, Cheolmin Park

Publikováno v: Materials Research Bulletin. 47:3027-3031

Industrial applicable fine-line double printing and nickel plating method was applied to single crystalline silicon (c-Si) solar cells. As the finger widths decreased, the efficiency and short circuit current density (JSC) linearly increased. Althoug

Simultaneous suppression of overlap errors and side-lobes in attenuated PSM lithography by rule-based OPC

Autor: Jun-Ha Lee, Hoongjoo Lee

Publikováno v: Microelectronic Engineering. 77:217-222

Problems of overlap errors and side-lobe printing by the design rule reduction in the lithography process using attenuated phase-shifting masks (attPSM) have been serious. Overlap errors and side-lobes can be simultaneously solved by the rule-based c
