What is the unit area mass of a solar cell?

The solar cell comprises a device stack of CPI/ITO/SnO 2 /Perovskite/Spiro-OMeTAD/Au, with a total thickness of less than 3 μm. 1.5 × 1.5 cm UTPSCs were fabricated and weighted to determine the unit area mass of the UTPSCs (Figure S20, Supporting Information). The unit area mass of the UTPSCs is as light as 4.3 g/m 2.

What is the power-law DOS in organic solar cells?

The linear dependence of the disorder on energy reveals the power-law DOS in organic solar cells. The density of states in organic disordered semiconductors is shown to follow a power-law distribution over a broad range of energies.
