Abstract:
A method for manufacturing a solar battery having at least two semiconductor thin-films and at least one conductive film, each of the semiconductor thin-films differing from the other in at least one of impurity concentration thereof and type of semiconductor, comprising steps of:a) forming at least one of the semiconductor thin-films, said step comprising: a sub-step of coating a liquid coating composition containing a silicon compound so as to form a coating film; and a sub-step of converting the coating film into a silicon film by at least one of heat treatment and light treatment b) forming at least one conductive film, said step comprising: a sub-step of forming a coating film on a substrate by coating a liquid material; and a sub-step of heating the coating film to convert it into a solid conductive film.
