[Printed Electronics World] The benefits of non-silicon photovoltaic materials are many and varied. Some are transparent, permitting the face of a wristwatch to generate power, the power source having zero footprints. Some, such as Dye Sensitised Solar Cells printed by G24i in the UK, generate electricity at narrow angles of incidence and even with polarised eg reflected light. DSSC designs can use light of all visible frequencies, not just sunlight. G24i’s initial target markets for its DSSC product include mobile phone chargers, particularly in the developing world.
