Why are crystalline silicon solar cells becoming more efficient?

Trends in photoelectric conversion efficiency of crystalline silicon solar cells over the past few years. Subsequent developments also require lower costs reduced from material costs and processing costs. First, the thickness of the silicon wafer is reduced, i.e., the development of a thin silicon process.

What are crystalline silicon solar cells?

During the past few decades, crystalline silicon solar cells are mainly applied on the utilization of solar energy in large scale, which are mainly classified into three types, i.e., mono-crystalline silicon, multi-crystalline silicon and thin film, respectively .

Why do screen-printed crystalline silicon solar cells need to be co-firing?

Besides, in terms of screen-printed crystalline silicon solar cells, the last step of co-firing causes the metal gate lines on the front surface to form good ohmic contact coupled with the silicon body. For the overly shallow junction depth, the metal will diffuse into the n-type area of the cell, thereby reducing the quality of the PN junction.

What is the thickness of crystalline silicon wafers for solar cells?

The existing thickness of crystalline silicon wafers for solar cells is nearly 180 μm, which will decrease in the future. However, for the existence of shallow junctions, the thin silicon process increases the surface recombination rates, so good surface passivation and other related processes are essential.

What are the assumptions of crystalline silicon solar cells?

Schematic diagram of crystalline silicon solar cells. For ideal solar cells, four main assumptions are proposed: there exists no transport loss, and the body recombination is minimal. Under the mentioned assumptions, the minimum Auger recombination and good free carrier collection can be obtained with the intrinsic substrate material.

Why does a thin silicon wafer affect the yield of a solar cell?

For instance, for the thermal expansion coefficient of the material and the difference in the composition of the slurry, the warping problem of the solar cell is caused, and the thinner silicon wafer exhibits even higher thinness, which is easy to cause debris, and therefore, to affect the yield.

Silicon Solar Cell

A traditional silicon solar cell is fabricated from a p-type silicon wafer a few hundred micrometers thick and approximately 100 cm 2 in area. The wafer is lightly doped (e.g., approximately 10 16 cm − 3) and forms what is known as the "base" of the cell. It may be multicrystalline silicon or single-crystal silicon.
