• Sommario/riassunto: Photovoltaic technology - or the direct conversion of light into electricity - is the fastest growing means of electricity generation today, however it is generally used outdoors. Relatively little attention has been focused on the many obstacles to overcome when designing efficient indoor products. As a result, indoor products are more often than not limited to low power. Designing Indoor Solar Products bridges this gap by showing where AES (Ambient Energy Systems) based on photovoltaic cells may be used for higher power devices. Motivated by both financial and ecological arguments,
