Table 1. Photovoltaic Parameters of Champion PSCs Based on Dopant-Free Polymeric HTMs and Doped Spiro-OMeTAD^a.

HTMs	JSCEQE [mA cm–2]	JSC [mA cm–2]	VOC [V]	FF [%]	PCE [%]
PC1	21.1	21.3	0.85	49.1	8.8
PC2	22.6	22.7	1.06	76.2	18.3
PC3	23.5	23.5	1.11	80.0	20.8
Spiro-OMeTAD	23.2	23.3	1.10	78.8	20.3 (doped)

^aJ_SC^EQE was calculated via wavelength integration of the standard AM1.5G emission spectrum.
