6 FAQs about [Cross section of n-type solar cell]

How efficient are n-type solar cells with boron-doped emitter and full-area passivating rear contact?

Fig. 1. Schematic cross-section of the n -type Si solar cell with diffused front boron-doped emitter and full-area passivating rear contact (TOPCon). In this work, we studied the efficiency of these cells experimentally as a function of wafer thickness W and resistivity ρb (i.e. the base doping) on a 25% efficiency level.

What are the different types of silicon solar cells?

In the past, exceptionally high silicon device performances have been realized with different cell designs (Figs. 1 and 2), which can be classified into FBC cells with a front junction (FJ) or back junction (BJ), and IBC cells with both contacts at the back side. Fig. 1: Overview of notable silicon solar cells.

How much JSC does a single junction c-Si solar cell have?

The observed efficiency increase with increasing thickness is, however, dominated by the strong increase in JSC from 42.2 mA/cm 2 for the 150 µm thick cells to over 43.0 mA/cm 2 for the 400 µm thick cells, with a peak value of 43.3 mA/cm 2 (cf. Table 1), which represents the highest JSC reported so far for single junction c-Si solar cells.

Do n-type C-Si solar cells benefit from a full-area passivating contact?

To benefit from both, a full-area passivating contact and a transparent dielectric surface passivation, we developed n-type c-Si solar cells with a B-diffused emitter at the front and a full-area TOPCon at the back 16 (Fig. 2d).

Which optical model is used to describe solar cells?

The optical model used to describe the solar cells is based on a lumped parameter approach, i.e. a front surface transmission T, calculated from the measured reflectance data excluding escape, and a pathlength enhancement Z, which was parameterized based on experimental EQE and R data as described in Ref. .

What are the characteristics of n-Fj solar cells?

The front side of the solar cells featured an alkaline-etched random-pyramid textured surface. The front surface of the n-FJ cells exhibited a boron-doped p + emitter, which was formed by BBr 3 diffusion at 870 °C in a tube furnace (centrotherm) followed by a drive-in oxidation at 1,050 °C.
