Solar cell key performance indicators Solar cell KPI allow quantitative monitoring of the most significant production parameters. In this work, the selected KPI is the Laminated Unit Power (Lam-UP) which represents the average power produced by cells that can be laminated (power higher than 3.650 W and without any aesthetic defect).
Yield, availability and performance ratio (PR) are the most common perfor mance indicators for solar power parks. Performance ratio is particularly interesting since it relates the theoretical power output of the system design to the power actually produced.
The Lam-UP parameter analysis along a year shows the impact of the serigraphy design change over the silicon solar cell production, taking in main that in such type of factories the implementation of new developments is a continuous task which can cause slight oscillations.
Laminated unit power and cell to module ratio are the selected key performance indicators for cell and module devices respectively. Laminated unit power shows a power increase from 3.95 W to 4.20 W directly related with frontal serigraphy design. Cell to module ratio for [4.30–4.35) W cell range indicates a decrease from 7.7% to 6.5%.
International Standard IEC 61724-1:2017 Photovoltaic system performance monitoring recognises that this is crucial and specifies the requirements for the measurement of global horizontal irradiance (GHI) and irradiance in the plane of array (POA, the same orientation and tilt as the solar panels).

Abstract — The highest efficiency solar cells provide both excellent voltage and current. Of these, the open-circuit voltage (Voc) is more frequently viewed as an indicator of the material quality. However, since the Voc also depends on the band gap of the material, the difference between the band gap and the Voc is a
