1：Experimental Design and Method Selection:

The study employed a bottom-up approach to create silicon solar cells using a line-shaped laser. The methodology included the deposition of amorphous/nanocrystalline silicon on glass, crystallization with a laser, and the implementation of heterojunction interdigitated back contact (HJ-IBC) architecture.

2：Sample Selection and Data Sources:

Samples consisted of polycrystalline silicon on glass substrates with varying thicknesses of amorphous silicon layers.

3：List of Experimental Equipment and Materials:

Equipment included a continuous wave diode laser for crystallization, plasma enhanced chemical vapor deposition (PECVD) for layer deposition, and a solar simulator for J-V measurements. Materials included Corning? Eagle XG? glass substrates and various silicon layers.

4：Experimental Procedures and Operational Workflow:

The process involved cleaning glass substrates, depositing silicon layers, laser crystallization, deposition of passivation and contact layers, and laser firing to reduce contact resistance.

5：Data Analysis Methods:

Data analysis included transmission electron microscopy (TEM) for layer thickness assessment, J-V measurements for electrical characterization, and quantum efficiency measurements.
