NOVELTY - Energy conversion module comprising solar cells comprises: transparent substrate (100); transparent electrode interconnection (200) disposed on transparent substrate; and several solar cells (300) disposed on transparent electrode interconnection, where each solar cell has at least one protrusion (310) formed on one surface of solar cell, and protrusion is bonded to transparent electrode interconnection.    USE - As energy conversion module comprising solar cells, for converting light energy into electrical energy (claimed). The solar cell module is useful as auxiliary power supply for portable information devices such as mobile phones or personal digital assistants (PDAs).    ADVANTAGE - The solar cell module has reduced thickness by eliminating printed circuit board (PCB) substrate, and can be manufactured by connection approach that does not include wire bonding, so that obtained solar cell module is lightweight, and ultra-thin. The transparent substrate protects underlying solar cell while providing for attachment of solar cell directly to transparent electrode interconnection without need for wire bonding. The solar cell has protrusions on one surface. The protrusions electrically conduct with first and second electrodes in solar cell and are bonded to transparent electrode interconnection such that solar cell is fixed onto transparent substrate. Also, recesses are formed at locations on transparent electrode interconnection corresponding to locations of protrusions, which mate with protrusions. Thus, protrusions on solar cell adhere to recesses in transparent electrode interconnection, and achieve flip-chip bonding.    DETAILED DESCRIPTION - Energy conversion module comprising solar cells comprises: transparent substrate (100); transparent electrode interconnection (200) disposed on transparent substrate; and several solar cells (300) disposed on transparent electrode interconnection, where each solar cell has at least one protrusion (310) formed on one surface of solar cell, and protrusion is bonded to transparent electrode interconnection. Recesses are formed at locations on transparent electrode interconnection in correspondence with locations of protrusions, and recesses mate with protrusions. Anisotropic conductive film (ACF) is interposed between transparent electrode interconnection and protrusion. The solar cells are electrically connected by transparent electrode interconnection. Two ends of transparent electrode interconnection act as first and second electrodes that allow contact with exterior of module, and first and second electrodes are disposed adjacent to one edge of transparent substrate. The module further comprises transparent resin surrounding solar cells.
