Indoor photovoltaics (IPV) hold enormous market potential driven by the rising demand for perpetual energy sources to power various small electrical devices and especially Internet of things (IoT) devices. Perovskite solar cells (PSCs) offer exciting prospects this role. This study sets out deepen our knowledge PSC performance under realistic indoor conditions. For purpose, we designed an monitoring system that maintains four at their maximum points simultaneously logs environmental Throughout a 12-month period, monitored behavior three PSCs one crystalline silicon cell (c-Si SC), all with active area approximately 1 cm2. Measured daily yields in conjunction comparative overview minimum requirements different wireless technologies indicate single cm2 should be enough IoT device available short-range, low-power on most days year, fact confirmed prototype device. There are, however, few every year when would not even point tracking, highlighting need least some storage capacity. Solar orientation dependence measurements demonstrated 36% advantage optimal 72% drop worst compared horizontal orientation. A one-year yield results show remarkable three-to-one favor best (148.8 mWh/cm2) over c-Si SC (46.0 mWh/cm2). The also retained its initial throughout simple edge-sealing encapsulation.
