Abstract
Photoelectrochemical cells with short term stability (at least) have been constructed from fracture surfaces of n‐type polycrystalline boules of CuInSe2. The recently developed electrolyte of Menezes [Appl. Phys. Lett. 4 5, 148 (1984)] appeared to have a passivating effect on grain boundaries. Samples with hundreds of boundaries easily attained half the best (12%) single crystal efficiency without any optimization. Microprobe analyses of the treated surfaces showed strong depletion of Cu and incorporation of I but the latter distribution appeared to be nonuniform. Poor fill factors were found on randomly fractured surfaces larger than 1 cm2. Only n‐type samples were successful.Keywords
