Abstract
A PV module includes a transparent substrate, a first solar cell unit, a crystalline silicon solar cell, and a spacer. The first solar cell unit is between the transparent substrate and the crystalline silicon solar cell, and the first solar cell unit includes a first electrode, a second electrode, and a I-III-VI semiconductor layer between the first electrode and the second electrode. The I-III-VI semiconductor layer includes at least gallium (Ga) and sulfur (S), and the energy gap thereof is more than that of crystalline silicon. Moreover, the crystalline silicon solar cell and the first solar cell unit are separated by the spacer.

A PV module, comprising:
- a transparent substrate;
- a crystalline silicon solar cell;
- a first solar cell unit located between the transparent substrate and the crystalline silicon solar cell, and the first solar cell unit comprises a first electrode, a second electrode, and a I-III-VI semiconductor layer between the first electrode and the second electrode, wherein the I-III-VI semiconductor layer comprises at least gallium (Ga) and sulfur (S) and an energy gap thereof is more than that of crystalline silicon;
- and
- a spacer, is configured to separate the crystalline silicon solar cell and the first solar cell unit, wherein the crystalline silicon solar cell is partially covered with the spacer so that a space is formed between the crystalline silicon solar cell and the first solar cell unit.
