Abstract

A model to predict the thermal and electrical performance of the PV mini-dish is proposed. The proposed model is expected to enable the PV mini-dish to perform sensitivity analyses of different solar cell model assumptions, environmental effects, heat sink and geometry, and thermal contact resistance. The model is also expected to optimize the heat sink geometric dimensions for a given volume. It is revealed that heat sink yields designs essentially similar to that which minimizes solar cell temperature. It is also determined that the diameter of the fin has a broad optimum (from 130-180 mm).
