Abstract

An unavoidable consequence of growing adoption of solar PV is an increase in PV systems deployed in non-optimal situations. This is particularly true with regard to irradiance. It is very likely that in a PV-powered future many systems will be set up such that they receive a substantial fraction of insolation in lowirradiance conditions. In this work, we present performance modeling of modules deployed in various climatic locales and orientations. We fabricate crystalline silicon heterojunction solar cells on wafers of different base resistivities and study their low illumination performance. We also calculate the energy yield gains from the performance improvements obtained from the cells with higher base resistivity.
