1. Introduction The idea of heterojunction silicon solar cells in both amorphous and crystalline configurations was introduced first by Fuhs et al. in 1974 [], and it later came into reality in 1983 when Hamakawa et al. reported a successful amorphous device with more than 9% power conversion efficiency (PCE) [].].

The use of thinner wafers and the …
Analysis of HIT Cells and Improvement | SpringerLink
In addition to heterojunction cells on n-type silicon, due to the relatively mature industry and relatively low price of p-type silicon, heterojunction cells on p-type substrates have also developed well. In 2009, NREL in the United States made heterojunction cells on).
Crystalline Silicon Solar Cells: Heterojunction Cells
The best measure for the quality of the passivation is the open-circuit voltage V oc, which, is in a HJT cell, in general, higher than 740 mV, e.g. V oc is about 15% higher for an HJT cell, than for conventional PERC cell, where we only obtain ~660 mV today.7.2.2 The Basic Structure of a Heterojunction Cell
