Abstract
A solar battery is provided having a structure in which at least two semiconductor thin-films are disposed one over the other between a pair of electrodes, each semiconductor thin-film differing from the other in the impurity concentration thereof and/or the type of semiconductor. Formation of at least one of the semiconductor thin-films consists of coating a liquid coating composition containing a silicon compound so as to form a coating film and a step of converting the coating film into a silicon film by heat treatment and/or light treatment.
