Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps.
In the case of front grids, the grid geometry is optimised such to provide a low resistance contact to all areas of the solar cell surface without excessively shading it from sunlight. Heterojunction solar cells are typically metallised (ie. fabrication of the metal contacts) in two distinct methods.
They are a hybrid technology, combining aspects of conventional crystalline solar cells with thin-film solar cells. Silicon heterojunction-based solar panels are commercially mass-produced for residential and utility markets.
In the case of the heterojunction cell, the metal layer is completely omitted, so that thinner wafers can be used for cell production. This leads to two opposite effects: A thinner wafer means that more light passes through the solar cell without being absorbed, so less light contributes to carrier generation.
The reference temperature is 25 °C according to STC (Standard Test Conditions). In contrast, the temperature coefficients of heterojunction solar cells are ~−0.3%/°C and the power decreases less with higher module temperatures.
In contrast, the temperature coefficients of heterojunction solar cells are ~−0.3%/°C and the power decreases less with higher module temperatures. Haschke et al. shows that solar modules with high Voc and lower Jsc perform better in hot environments than modules with the same power but lower Voc and higher Jsc.
