Two techniques used to improve the efficiency of existing PV panels: Thermal management & PERC technology

Abstract

Current solar panels can be improved using several techniques that boost the efficiency and cell performance. Looking in the latest studies currently on-going in the laboratories, two main fields were mostly taking a considerable success: PERC technology and passive thermal management. PERC technology involves the addition of a dielectric passivation layer to the already existing layers in the p-type crystalline wafers. This helps trap more sunlight and generate more electricity, thus improving the crystalline silicon panel. In addition, proper thermal management of photovoltaics leads to better heat dissipation, which improves the conversion of sunlight to electricity and maintains a stable panel performance in the long run.
