Latest Patents

One of Rostan's latest patents is a method for fabricating a solar module of rear contact solar cells using linear ribbon-type connector strips. This innovative approach describes a solar module that comprises a plurality of rear contact solar cells, which are designed with a large size of approximately 156×156 mm. The soldering pad arrangements applied on emitter and base contacts are arranged linearly and asymmetrically with respect to a longitudinal axis. Each solar cell is separated into first and second cell portions along a line perpendicular to the longitudinal axis. This unique design allows for the first and second cell portions to be arranged alternately, with each second cell portion oriented at a 180° angle relative to the first. The interconnection of these cell portions is achieved using simple linear ribbon-type connector strips, which are soldered onto the aligned emitter and base soldering pad arrangements. This method not only simplifies the interconnection process but also reduces bowing and series resistance losses.
