Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Perovskite solar cells (PSC) demonstrate good performance in an indoor environment and this feature can be used for powering indoor sensors. Since indoor light is not always available, the sensor should have backup energy storages. The charger circuit model allows performance optimization for batteries and photovoltaic (PV) cells so that a cost-effective condition can be achieved for powering practical devices. This paper presents the performance evaluation of fractional open-circuit voltage (FOCV) maximum power point tracking (MPPT) charging circuit under indoor conditions. Simulations were done for 0.03, 0.07, 0.15, 0.25, 0.40, 0.70 and 1.00 sun irradiance as a preliminary study.
