WELCOME TO APV2025

“About SIMPOSIUM APV 2025”

A photovoltaic device, or more commonly known as a solar cell, is a technology that directly converts light into electricity through absorption of photon energy via the band energy gap of semiconductor materials. It is promising as an alternative future energy source because of its renewable nature, environmentally friendly attributes, low cost, and ability to provide independent energy resources. Recently, the development of photovoltaic (PV) technology has been progressing significantly from lab to fab. The first crystalline silicon with power conversion energy of 6% was envisioned by Bell Lab in 1954 and now it has exceeded 27% for silicon based solar cells. Meanwhile, Indonesia has huge natural resources as feedstock to third generation PV technologies such as titanium, tin, lead, and copper. At the same time, Indonesia as a tropical country faces challenging environmental conditions for photovoltaic device fabrication which requires controlled environment such as low humidity and cool temperatures. In this regard, lessons learned from studies reported from universities and research institutions abroad need to be adapted to local environments. Nevertheless, connecting to key researchers globally are needed to allow knowledge exchange as much as fostering networks among Indonesian photovoltaic researchers to raise the quality of advanced PV research in Indonesia collectively.

Before 2023, there was no domain-specific forum of researchers dedicated to advanced photovoltaic technologies. We then initiated a symposium on advanced photovoltaics sponsored by National Research and Innovation Agency Republic of Indonesia or Badan Riset dan Inovasi (BRIN) Indonesia in 2023. The first symposium was conducted hybrid and attracted 170+ registered participants from 5 countries including Indonesia with about 50 participants attended offline at BRIN. During the first symposium, there are 3 keynote speakers, 6 invited speakers and 8 young scientist presenters. The 2023 symposium was concluded with the launching of Indonesian Solar Cell Research Society, an Indonesian scientific community dedicated for solar cell enthusiast. Reflecting on the huge enthusiasm and acceptance of our first conference two years ago, Research Center for Electronics, BRIN & Indonesian Solar Energy Research Society (ISERS) will organize the 2nd symposium on advanced photovoltaics in full online format to accommodate more participants both locally and globally. We foresee this symposium as a flagship platform of knowledge exchange for advanced PV materials and device researchers. Objectives

The objectives of the 2nd Symposium on Advanced Photovoltaics 2025 are as follows.

1.To open a global network of Indonesian researchers who actively engage in photovoltaic research either among domestic or overseas researchers;

2.To provide a platform for knowledge sharing, synergy and collaboration to advance the photovoltaic research in Indonesia; and

3.To facilitate technical discussion related to advanced photovoltaics, such as emerging technologies, novel materials, performance improvement, and reliability enhancement.
