6 FAQs about [GaAs photovoltaic panel production enterprises]

What is a GaAs thin-film solar cell?

The GaAs thin-film solar cell is a top contender in the thin-film solar cell market in that it has a high power conversion efficiency (PCE) compared to that of other thin-film solar cells. There are two common structures for the GaAs solar cell: n (emitter)-on-p (base) and p-on-n.

How efficient are GaAs solar cells?

We have measured all the GaAs cells properly fabricated on 2 inch wafer. The efficiency was slightly varied from cell to cell over the whole wafer but the most of cells exhibit efficiencies of more than 21% and the minimum efficiency was at least 20.84%. Thus, these highly efficient GaAs solar cells are reliably demonstrated.

What is N-on-p structure of GaAs solar cell?

The inverted structures of GaAs solar cell grown using MOCVD becomes a conventional n-on-p structure after ELO process. The single-junction GaAs thin-film solar cell on a flexible substrate is made using the standard solar cell fabrication process.

Does a fabricated GaAs thin-film solar cell have N- and P-ohmic metal layers?

Both n- and p-ohmic metal layers as well as the GaAs active region are clearly visible in this cross-sectional SEM image of a fabricated GaAs thin-film solar cell obtained using a focused ion beam (FIB). Figure 2 shows the measured external quantum efficiency (EQE) and reflectance curves of the fabricated GaAs thin-film solar cell.

Could a GaAs-based thin-film solar cell be the leader of the future?

In particular, a GaAs-based thin-film solar cell could be the leader of the future thin-film solar cell market because of its unri v aled high efficiency (28.8%, Alta Devices, Sunnyvale, CA, USA 1), long-term stability, and reasonable cost 2.

What is the structure of a GaAs solar cell?

There are two common structures for the GaAs solar cell: n (emitter)-on-p (base) and p-on-n. The former performs better due to its high collection efficiency because the electron diffusion length of the p-type base region is much longer than the hole diffusion length of the n-type base region.
